Posicionamento por DGPS: experimentos para avaliação das técnicas RDS, NTRIP e DGPS

Results from differential positioning experiments obtained using real-time DGPS method performed in field measurements are the subject of this paper. The ways to transmit differential corrections as well as some results using the DGPS network concept in the post-processed mode are presented and discussed. It was noticed that the positioning accuracy was ca. 15% better using the DGPS-NTRIP technique in comparison to DGPS-RDS. By using DGPS network technique, the positioning accuracy was enhanced from 1,9 up to 5,3 times. Also a precision improvement from 1,5 up to 1,75 times was verified if compared to the single baseline positioning.
