Abstract:

Pemantauan posisi Candi Borobudur bertujuan untuk menjaga warisan dunia. Salah satu caranya adalah dengan pembangunan bench mark (BM) atau titik kontrol untuk pemantauan deformasi menggunakan Global Positioning System (GPS). Pengukuran menggunakan teknologi GPS untuk pemantauan stabilitas Candi Borobudur telah dilakukan pada tahun 2002, 2003, dan 2012, menggunakan Global Kalman Filter VLBI dan analisis GPS dan mengacu pada ITRF2000 untuk menganalisis pergeseran horisontal. ITRF menuntut pemutakhiran data koordinat titik-titik kontrol secara periodik. Perbedaan penggunaan versi ITRF pada pengolahan data GPS berdampak pada perbedaan ketelitian estimasi posisi, besar kecepatan dan arah pergeseran titik-titik kontrol. Tujuan dari penelitian ini adalah untuk mengukur estimasi posisi, kecepatan, dan arah pergerakan dari titik control GPS berdasarkan data 2003 dan 2012 dan mengacu pada ITRF2008. Masing-masing kala melalui tahapan regional processing dan local processing. Koordinat dari hasil local processing GAMIT/GLOBK selanjutnya dibandingkan dengan koordinat hasil olahan mengacu ITRF2000 yang telah ditransformasi menjadi koordinat mengacu ITRF2008. Analisis pergeseran titik berdasarkan koordinat dan hasil dari data 2003 dan 2012. Penelitian ini menghasilkan bahwa perbedaan posisi dan akurasi pada pengolahan regional dan lokal mengindikasikan transformasi dari ITRF2000 ke ITRF2008 berada pada standar deviasi yang dihasilkan GAMIT dan GLOBK yang mengacu pada ITRF2008. Selanjutnya, rata-rata nilai pergeseran horisontal periode 2003 dan 2012 adalah 261 mm arah tenggara (SE) yang serupa dengan penggunaan ITRF2000 pada penelitian sebelumnya. Secara umum, perataan jaring Candi Borobudur yang mengacu pada ITRF 2008 lebih akurat dibandingkan penelitian sebelumnya yang mengacu pada ITRF2000.

Abstract:

Resumo:As transformações de coordenadas e velocidades entre as realizações do ITRS (International Terrestrial Reference System), bem como a atualização de coordenadas, tornar-se-ão tarefas rotineiras em levantamentos geodésicos devido ao emprego de sistemas de referência dinâmicos e ao movimento das placas tectônicas. Neste estudo foram realizadas compatibilizações de sistemas de referência (ITRF2000, ITRF2005 e ITRF2008) das coordenadas e velocidades com suas respectivas estimativas de precisão, via propagação de variância, de 11 estações distribuídas nas placas tectônicas Norte e Sul Americanas e da Eurásia. Foi verificado com base nas coordenadas nos ITRF2008, época 2005 e ITRF2005, época 2000, obtidas pelo IERS (International Earth Rotation and Reference System Service), que 54,55% das discrepâncias planimétricas são centimétricas e 45,45% decimétricas. Comparando as coordenadas no ITRF2008, época 2005,0 e no ITRF2000, época 1997,0 verificou-se discrepâncias planimétricas da ordem do decímetro para todas as estações. Confrontando as coordenadas ITRF2000, época 1997,0 obtidas pelo IERS com as calculadas com base nas transformações entre sistemas de referência e atualizações verifica-se discrepâncias planimétricas da ordem do milímetro em 72,73% dos casos e da ordem do centímetro em 27,27%. As análises realizadas confirmam a necessidade de atualizar e compatibilizar o referencial das coordenadas e velocidades para aumentar a acurácia do posicionamento

Abstract:

Solving Multiple Attribute Group Decision Making (MAGDM) problems has become one of the most important researches in recent days. In situations where the information or the data is of the form of an Intuitionistic Triangular Fuzzy Number (ITrFN) or Intuitionistic Trapezoidal Fuzzy Number (ITzFN), a new distance function is defined for ranking the alternatives in the decision making process. After processing the decision information through a sequence of arithmetic aggregation operators, namely, the Intuitionistic Triangular Fuzzy Weighted Arithmetic Averaging (ITrFWAA), Intuitionistic Triangular Fuzzy Ordered Weighted Averaging (ITrFOWA) operator and the Intuitionistic Triangular Fuzzy Hybrid Aggregation (ITrFHA) operator, the proposed distance function is utilized to rank the best alternative. A model is proposed to solve MAGDM problems using the developed distance formula defined for ITrFNs. Numerical illustration is provided and comparisons are made with some of the existing MAGDM models and ranking procedures.

Abstract:

La oficialización del marco CR-SIRGAS implica la necesidad de transformar la información vinculada al marco anterior a esta nueva referencia nacional. Se presentan los resultados de un análisis efectuado en la determinación de varios conjuntos de parámetros de transformación entre el antiguo marco geodésico CR05 y el marco geodésico CR-SIRGAS. Este proceso contempló el estudio de la transformación directa entre ambos marcos contemplando dos variantes, así como también, una secuencia de transformaciones igualmente en dos variantes considerando las soluciones ITRF que se han dado desde la implementación del CR05. Este proceso denominado transformación en escalera consideró la afectación que produjo el terremoto de Mw 7,6 en la península de Nicoya en agosto de 2012 [1] y [2] sobre los vértices de la red geodésica nacional activa y pasiva del CR05. Considerar los aspectos geométrico y físico es indispensable en una adecuada y correcta georreferenciación. Se usó el modelo de transformación baricéntrico [3] y [4] para seis parámetros: las tres traslaciones entre los orígenes y las tres rotaciones de los ejes [5]. En cada uno de los procesos de cálculo se analizaron los residuales en componentes topocéntricas [N, E, U]. Se ofrece como resultado dos conjuntos de seis parámetros de transformación desde el marco nacional CR05, época de referencia 2005,83, marco ITRF2000 al marco nacional CR-SIRGAS, época de referencia 2014,59, marco ITRF2008. Además, de dos conjuntos de seis parámetros entre CR05 y CR-SIRGAS contemplando diferentes soluciones ITRF y sus respectivas épocas. En cada determinación se expone el comportamiento de los residuales.

Abstract:

O sistema de referência oficial adotado no Brasil é o SIRGAS2000 (densificação do ITRF2000) e foi realizado na época 2000,4. Desde a semana GPS 1709 (07/10/2012), o referencial adotado pelo IGS (International GNSS Service) para as efemérides precisas é o IGb08 (ITRF2008). Desse modo, os serviços que realizam o Posicionamento por Ponto Preciso (PPP) e empregam essas efemérides no processamento fornecem as coordenadas das estações nesse referencial e na época de coleta dos dados. Portanto, torna-se necessário realizar a transformação das coordenadas do IGb08 (ITRF2008, época de coleta dos dados) para o SIRGAS2000 (ITRF2000, época 2000,4). Para realizar essa tarefa existem, pelo menos, 45 possibilidades, pois há pelo menos 3 conjuntos de parâmetros de transformação que podem ser usados em conjunto com pelo menos 15 modelos de velocidade. O objetivo deste trabalho é avaliar essas possibilidades no IBGE-PPP. Foram processados dados de 86 estações da RBMC (Rede Brasileira de Monitoramento Contínuo dos Sistemas GNSS) coletados no dia (15/07/2013). Os resultados mostram que a melhor possibilidade de transformação de referencial e atualização de coordenadas, na média, é aquela que utiliza os parâmetros de transformação disponibilizados por Petit e Luzum (2010), juntamente com o modelo de velocidade MORVEL2010.

Abstract:

From a network of ninety-six (96) Continuously Operating Reference Stations (CORS), the Department of Survey and Mapping Malaysia (DSMM) has developed a reliable real-time data streaming service known as the Malaysia Real-Time Kinematic GNSS Network (MyRTKnet). MyRTKnet is now operating on Leica SpiderNet system that is configured to provide coordinate to users in Geocentric Datum of Malaysia 2000 (GDM2000). As the name implied, GDM2000 is a geocentric datum for Malaysia, developed based upon the International Terrestrial Reference Frame (ITRF) 2000 or ITRF2000. One could argue that the quality of coordinates provided by MyRTKnet are less optimal as the latest realisation of ITRF at present is ITRF2014. This study aims to investigate the accuracy and precision of the resultant coordinates from MyRTKnet real-time services through a comparison with the control-quality coordinates from a network of post-processed data at some independent points for positioning purpose. Meanwhile for mapping purpose, the coordinates from Network Real-Time Kinematic (NRTK) at selected Cadastral Reference Marks (CRM) points were compared with their known values. The results show that the observed points in ITRF2000 move approximately 37 cm away from the points in ITRF2014 due to the constant movement of Sundaland Block. Meanwhile for the assessment of NRTK technique, there is no significant displacement for coordinates in ITRF2000 but ITRF2014 with the values of 4.4 and 39.8 cm at KDOJ point, respectively. The discrepancy in ITRF2014 could be due to the improper datum transformation procedure.

Abstract:

The paper presents the GOP first reprocessing results, which officially contributed to the EPN-repro1 project. It also describes the 15-year GOP cumulative solution providing station coordinates, velocities and their discontinuities over the period of 1996-2011. Repeatabilities estimated from cleaned long-term coordinate time-series reached 1-2 mm and 4-6 mm in horizontal and vertical component, respectively. We then showed the exploitation of GOP reprocessing results in the assessment of the EUREF ITRF2005 densification and the latest ITRS realization, ITRF2008. We identified and confirmed the North-South tilt (≈ 2mas) in the currently available European reference frame based on the EPN cumulative solution updated in GPS week 1600. The study showed a historical development of the tilt and its close relation to a weak velocity datum definition of this realization, which is very important for a long-term datum prediction. Selected EPN station coordinates, velocities and discontinuities of the latest ITRS realization (ITRF2008) were also assessed. Specific problems for some EPN stations were identified in the global reference frame. This emphasized further necessity to check all the stations before their use for datum definition for regional densifications.

Abstract:

ITRFs and ITRF like reference frames have a drawback that limits or makes its wide use difficult while surveying in the Russian Federation. These are significant velocities of changing geodetic stations’ coordinates throughout the entire territory. It leads to necessity of reducing reference geodetic stations and survey points positions from reference epoch to observation ones and vice versa. To avoid this necessity for the most of surveys in the Russian Federation territory, a transformation model [1] of relative behaviour of GSK-2011 and ITRF-2014 reference frames was created. Unfortunately, the model does not work properly in the Far East. That is why in this paper a new, regional transformation model that represent relative behaviour of GSK-2011 and ITRF-2014 reference frames in the territory was described. As it was shown in the paper, the result is equivalent to setting a new, auxiliary version of GSK-2011 reference frame in the Far East territory – GSK-2011-FE, that has no drawbacks of ITRF-like systems. Both frames coincide with each other at the reference epoch t0 and relate by a transformation of angular motion at an epoch t.

Abstract:

AbstractThe PTRF is based on 43 sites with 64 SSC collocation points with the optimum geographic distribution, which were selected from all stations of the ITRF89 according to the criterion of the minimum value of the errors of 7 parameters of transformation. The ITRF89 was computed by the IERS Terrestrial Frame Section in Institut Geographique National - IGN and contains 192 VLBI and SLR stations (points) with 119 collocation ones. The PTRF has been compared with the ITRF89. The errors of the 7 parameters of transformation between the PTRF and 18 individual SSC as well as the mean square errors of station coordinates are of the same order as those for the ITRF89. The transformation parameters between the ITRF89 and the PTRF are negligible and their errors are of the order of 3 mm.

Abstract:

O IBGE-PPP, serviço de Posicionamento por Ponto Preciso (PPP) online, estima coordenadas originalmente referenciadas às materializações do ITRF (IGS) e então as compatibiliza para o SIRGAS2000 com a aplicação da transformação de Helmert e seus respectivos parâmetros de transformação. Em 17 de maio de 2020 o IBGE-PPP passou a utilizar um novo conjunto de parâmetros (P2), descontinuando o conjunto antigo (P1). Nesse contexto, este trabalho se propõe a avaliar os impactos dos novos parâmetros na compatibilização de referenciais e redução de coordenadas utilizados pelo IBGE-PPP, fundamentando-se em análise de séries temporais de dados de duas estações da RBMC, NAUS e AMCO. Analisando as séries temporais SIRGAS2000 compatibilizadas com P1 (SCP1) e P2 (SCP2) para as duas estações, observou-se que as séries de componentes norte (Δn) SCP1 apresentaram mudanças de nível (diferenças) de aproximadamente ±0,017 m e –0,013 m em relação a SCP2, nos períodos referentes às materializações do ITRF2005 (IGS05) e ITRF2014 (IGS14). As séries de componentes leste (Δe) e vertical (Δu) SCP1 também apresentaram diferenças quando comparadas à SCP2, porém com magnitudes entre 0,001 m e 0,006m e 0,004 m e 0,012 m, respectivamente. Considerando os conjuntos de parâmetros de transformação entre as materializações ITRF (IGS) e SIRGAS2000, pôde-se observar que as séries SCP2 apresentaram resultados mais consistentes quando comparadas às séries SCP1, diminuindo os impactos causados pelas trocas de referenciais ocorridas ao longo do tempo. Ademais, as séries SCP2 foram compatíveis com as séries referenciadas ao ITRF2014 (IGS) ao nível menor ou igual a 0,002 m.

Abstract:

According to the Order of the Ministry of Agrarian Policy of Ukraine, published in 2016, about the procedure for using the national coordinate system UCS-2000, this was the first time officially presented parameters of the Helmert transformation from the UCS-2000 system to the ITRF-2000 system. However, all software products are used for communication between various coordinate systems as the main coordinate system, WGS-84. The Helmert transformation parameters between the UCS-2000 and WGS-84 systems are found for the new realization of WGS-84 (G1762) based on GPS data and the old realization of the WGS-84, based on the US Satellite Navigation System, known as DOPPLER Transit. It is shown that the use of the transformation parameters of the old realization WGS-84 for the processing of present GPS measurements will result in a systematic error of the order of 0.6 m. Obtained transformation parameters can be used as the first approximation to obtain accurate Helmert transformations based on GPS measurements at points with known coordinates in the UCS-2000 system. The described procedure for determining the parameters will be especially useful in the case when a more accurate connection will be established between the systems ITRFyy and WGS-84, than the current one.

Este trabalho objetivou estudar a seletividade dos inseticidas carbaril, deltametrina, paratiom metílico, permetrina e triclorfom em relação a Ascia monuste orseis (Godart) (Lepidoptera: Pieridae) e a seus predadores Brachygastra lecheguana Latreille e Protonectarina sylveirae (Saussure) (Hymenoptera: Vespidae). Por meio de curvas de concentração-mortalidade e das concentrações letais para 90% da população (CL90), calcularam-se os índices de seletividade diferencial (ISD90), de toxicidade relativa, e de tolerância relativa (ITRe90). O paratiom metílico e triclorfom apresentaram seletividade em favor de B. lecheguana (ISD90 = 2,83 e 1,75) e P. sylveirae (ISD90 = 2,95 e 3,59) em relação a A. monuste orseis. Deltametrina e permetrina apresentaram seletividade em favor de P. sylveirae (ISD90 = 1,98 e 2,70) em relação a A. monuste orseis, mas não apresentaram seletividade em favor de B. lecheguana (ISD90 = 0,21 e 0,64). B. lecheguana foi menos tolerante a deltametrina, permetrina e triclorfom do que P. sylveirae (ITRe90 = 9,36, 4,23 e 2,05), e mais tolerante ao carbaril (ITRe90 = 0,14). Os predadores apresentaram tolerância semelhante ao paratiom metílico (ITRe90 = 1,04). As curvas de concentração-mortalidade do carbaril, permetrina e triclorfom em ambos os predadores, de deltametrina em B. lecheguana, e de paratiom metílico em P. sylveirae, apresentaram maiores inclinações do que as curvas em A. monuste orseis.

Abstract:

The Southeast Asia region is mostly surrounded by active subduction zones in which the Australian plate, the Indian plate, and the Philippine Sea plate submerges beneath the continental plates and blocks. The Sunda block covers the large part of the Southeast Asia region, which comprises of Indochina, the South China Sea, the northeastern part of Sumatra, Borneo, the northern part of Java, and the shallow seas in between. We collect the GPS data in the whole Southeast Asia region for the period from 1994 to 2016, and process the original carrier phase data of GPS using GAMIT/GLOBK 10.6 to obtain the velocity field in the International Terrestrial Reference Frame, ITRF2008. The velocity field thus obtained is utilized to update the Euler rotation parameters of the Sunda block in ITRF2008, and model the long-term slip rates between the adjacent plate and blocks. In this study, we model the Sunda block and the Sumatra block together with the Australian plate by using TDEFNODE. The estimated Euler pole parameters of the Sumatra and Sunda blocks are estimated as their locations at (37.4°S, 106.8°E) and (46.2°N, 89.4°W), respectively, and their angular velocities of 0.371°/Myr clockwise, and 0.327°/Myr counter clockwise, respectively. These parameters result in the slip rate of the Sumatra fault with magnitude of ~9 mm/yr.

Abstract:

Abstract. At present, ITRS series reference frameworks are widely used in the world. The results of GNSS are mostly based on the ITRF framework. Transform from ITRF to CGCS2000 is not easy, which restricts the promotion and use of CGCS2000. The conversion relationship between CGCS2000 and ITRF framework has imminent practical significance. This paper constructs the epoch reduction and frame conversion two-steps model which estimated the nonlinear model to solve the appeal problem. Effective test show that the nonlinear model accesses an improvement in not only precession but also accuracy relative to the tradition model.

Abstract:

In this paper, we present detail data of Pliocene - present tectonics and strain rate from GPS measurement and seismic interpretation. Using international reference frame ITRF08, we revealed absolute tectonic velocities of GPS sites with the slip rate to the east between 22 to 25 mm/year, to the south between 4 to 8 mm/year. The present strain rate was determined from present tectonic velocities that were consistent with the recent strain rates determined from seismic profiles, thickness of Pliocene - Quaternary sediments. Present day strain rate varying from 10 to 30 nano per year indicated that the region has been deformed weakly, in a stable tectonic regime.

Abstract:

Abstract. A terrestrial reference frame (TRF) is a basis for precise orbit determination of Earth-orbiting satellites, since it defines positions and velocities of stations, the tracking data of which are used to derive satellite positions. In this paper, we investigate the impact of the International Terrestrial Reference Frame realization ITRF2014, as compared to its predecessor ITRF2008, on the quality of orbits, namely, on root-mean-square (rms) fits of observations and orbital arc overlaps of three altimetry satellites (TOPEX/Poseidon, Jason-1, and Jason-2) in the time interval from August 1992 to April 2015 and on altimetry products computed using these orbits, such as single-satellite altimeter crossover differences, radial and geographically correlated mean sea surface height (SSH) errors and regional and global mean sea level trends. The satellite orbits are computed using satellite laser ranging (SLR) and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) observations of a global network of stations. We have found that using ITRF2014 generally improves the orbit quality as compared to using ITRF2008. Thus, the mean values of the rms fits of SLR observations decreased (improved) by 2.4 % and 8.8 % for Jason-1 and Jason-2, respectively, but are almost not impacted for TOPEX/Poseidon when using ITRF2014 instead of ITRF2008. The internal orbit consistency in the radial direction (as derived from arc overlaps) is reduced (improved) by 6.6 %, 2.3 %, and 5.9 % for TOPEX/Poseidon, Jason-1, and Jason-2, respectively. Single-satellite altimetry crossover analyses indicate reduction (improvement) in the absolute mean crossover differences by 0.2 mm (8.1 %) for TOPEX, 0.4 mm (17.7 %) for Jason-1, and 0.6 mm (30.9 %) for Jason-2 with ITRF2014 instead of ITRF2008. The major improvement of the mean values of the rms of crossover differences (0.13 mm; 0.3 %) has been found for Jason-2. Multi-mission crossover analysis shows slight improvements in the standard deviations of radial errors: 0.1 %, 0.2 %, and 1.6 % for TOPEX, Jason-1, and Jason-2, respectively. The standard deviations of geographically correlated mean SSH errors improved by 1.1 % for Jason-1 and 5.4 % for Jason-2 and degraded by 1.3 % for TOPEX. The change from ITRF2008 to ITRF2014 orbits only has minor effects on the estimation of regional and global sea level trends over the 22-year time series from 1993 to 2015. However, on interannual timescales (3–8 years) large-scale coherent trend patterns are observed that seem to be connected to drifts between the origins of the tracking station networks. This leads to the changes in interannual global mean sea level of up to 0.06 mm yr−1 for TOPEX, 0.05 mm yr−1 for Jason-1, and up to 0.12 mm yr−1 for Jason-2, i.e., up to 4 % of the corresponding sea level signal based on altimetry for timescales of 3 to 8 years. The respective changes in the regional sea level trend on these timescales are up to 0.4 mm yr−1 in the time span from April 1993 to July 2008 and up to 1.0 mm yr−1 in the time span from July 2008 to April 2015.

Abstract:

Two coordinate systems used in Turkey, namely the ED50 (European Datum 1950) and ITRF96 (International Terrestrial Reference Frame 1996) coordinate systems. In most cases, it is necessary to conduct transformation from one coordinate system to another. The artificial neural network (ANN) is a new method for coordinate transformation. One of the biggest advantages of the ANN is that it can determine the relationship between two coordinate systems without a mathematical model. The aim of this study was to investigate the performances of three different ANN models (Feed Forward Back Propagation (FFBP), Cascade Forward Back Propagation (CFBP) and Radial Basis Function Neural Network (RBFNN)) with regard to 2D coordinate transformation. To do this, three data sets were used for the same study area, the city of Trabzon. The coordinates of data sets were measured in the ED50 and ITRF96 coordinate systems by using RTK-GPS technique. Performance of each transformation method was investigated by using the coordinate differences between the known and estimated coordinates. The results showed that the ANN algorithms can be used for 2D coordinate transformation in cases where optimum model parameters are selected.

Abstract:

The north-western part of the Hellenic Volcanic Arc was studied by Differential GPS measurements in an attempt to investigate the regional deformation of the area. The GPS network involving stations in Athens, Aegina Island, Methana Peninsula and Soussaki was established in February 2006 and since then it was reoccupied twice. The GPS measurements were primarily referred to Worldfixed reference frame (ITRF2000) and then to Europe and Athens as well. The observed velocities for the overall three-year spanning period according to Athens station showed rates at the order of 7-10 mm/yr, while the directions of the displacements tend towards NNW to NNE. The results of the horizontal velocities with respect to Europe indicate rates of SW directions, exhibiting higher magnitudes (25-26±2mm/yr) in the western and southern part of the Saronikos Gulf than in its central part (20±7 mm/yr). The horizontal velocities with respect to ITRF2000 showed consistent SE directions with higher rates in Aegina (12±7 mm/yr) than in Soussaki and Methana (9±3 mm/yr). A kinematic interpretation based on velocity and strain rates is finally attempted on the basis of the regional tectonics in the Saronikos Gulf.

Abstract:

Zusammenfassung. Die vorliegende Untersuchung überprüft die Konstruktvalidität einer 16 Items umfassenden Kurzversion der Integrated Teacher Report Form (ITRF), einem universellen und unterrichtsrelevanten Verhaltensscreening zur Diagnostik des externalisierenden Verhaltens von Schüler_innen im Klassenraum. 107 Lehrkräfte bearbeiteten für insgesamt 1048 Schülerinnen und Schüler der ersten bis sechsten Klasse die ITRF sowie zusätzlich jeweils eines von drei im deutschsprachigen Raum etablierten Beurteilungsverfahren. Die Analyse der konvergenten und diskriminanten Validität erfolgt anhand einer Multitrait-Multimethod (MT-MM) Korrelationsmatrix sowie einem strukturprüfenden Correlated Trait-Correlated Method minus 1 [CT-C(M-1)] Modell zur separaten Analyse des Einflusses der Konstrukte (lernbezogene / aufmerksame Verhaltensprobleme, oppositionelle / störende Verhaltensprobleme) und der Methoden (ITRF, zusätzliches Beurteilungsverfahren) auf die erzielten Werte der Beurteilungen. Die Ergebnisse zeigen, dass sich die Stärke der theoretisch postulierten Korrelationen mit den empirischen Daten erwartungskonform abbilden lassen, was auf konvergente und diskriminante Validität hinweist. Die Varianz der ITRF-Werte lässt sich zu einem größeren Anteil durch das zu messende Konstrukt als durch methodenspezifische Einflüsse erklären. Somit liefern unsere Befunde Evidenz für eine angemessene Konstruktvalidität des Verfahrens, weshalb sich die Kurzversion der ITRF für den praktischen Schuleinsatz eignet.
