The purpose of this study was to show reliability of combined and satellite only GGMs. It was an experimental research study that compare with terrestrial data and EGM2008. The GGMs were selected with three different category; tide system, degree/order and year. Gravity anomaly, gravity disturbance and height anomaly were computed from each models within Sri Lankan region by dividing number of grids and compared with same quantities of EGM2008 using ICGEM Calculation Service & Generic Mapping Tool (GMT). The major conclusion to this study was that relatively smaller STDs for height anomaly are…mehr

The purpose of this study was to show reliability of combined and satellite only GGMs. It was an experimental research study that compare with terrestrial data and EGM2008. The GGMs were selected with three different category; tide system, degree/order and year. Gravity anomaly, gravity disturbance and height anomaly were computed from each models within Sri Lankan region by dividing number of grids and compared with same quantities of EGM2008 using ICGEM Calculation Service & Generic Mapping Tool (GMT). The major conclusion to this study was that relatively smaller STDs for height anomaly are obtained from EGM2008 and GGMplus when compared with terrestrial data. And categorized GGMs were compare with EGM2008 finally can say high degree combined GGM was well fit for Sri Lankan region.
Autorenporträt
Vasuthavan Suvetharanyan si è laureato all'Università di Sabaragamuwa in Scienze della misurazione (misurazione e geodesia). Lavora come geometra in un'importante società di costruzioni dello Sri Lanka. Vorrebbe studiare i modelli gravitazionali e le relative missioni satellitari e vorrebbe partecipare alle ricerche sui GGM analizzati per area.
