GPS Trimble R8 GNSS prietaiso tikslumo įvertinimas / The Analysis Of GPS Instrument Trimble R8 GNSS Measuring Accuracy

Žvironas, Andrius 14 January 2009 (has links)
Nagrinėjama GPS prietaiso Trimble R8 GNSS tikslumas. Tirta sudaryto geodezinio pagrindo tikslumo charakteristikos, remiantis atliktais GPS (globalinės padėties taškų nustatymo sistema) matavimais ir išskaičiuotomis geodezinio pagrindo punktų koordinatėmis. Atlikta analizė rodo, kad anksčiau sudarytas trianguliacijos tinklas yra aukšto tikslumo ir pilnai tenkina bei ateityje tenkins Kauno miesto geodezinio pagrindo reikalavimus, todėl punktų koordinates keisti būtų netikslinga. Apskaičiuotąsias GPS matavimais punktų koordinates vietinėje sistemoje tikslinga būtų taikyti, vykdant tik aukšto tikslumo geodezinius darbus. / The analysis GPS instrument Trimble R8 GNSS accuracy. Precision characteristics of performed geodesic basis were examined according to GPS (global location point determination) measurement and calculated coordinates of points of geodesic basis. The analysis showed, that triangulation net that was made earlier is of high precision and meets completely and will meet in the future the needs of city geodesic basis, therefore it is not expedient to change the coordinates of the points. The application of point coordinates calculated according to GPS (global location point determination) measurement in local system would be expedient when prosecuting geodesic works of high precision only in the city and coordinates of old planimetric net should be used for performance of gross scale topographical photos, for land cadastral works and other works of applied geodesy.
