PPP em tempo real com estimativa das correções dos relógios dos satélites no contexto de rede GNSS
(Universidade Estadual Paulista (UNESP), 2014)
Real time ppp applied to airplane fligtht tests
(2019-01-01)
The availability in real time of GNSS satellites orbits, clock corrections and code and phase biases provided the possibility of application of Real Time Precise Point Positioning (RTPPP). This paper presents the methodology ...
Posicionamento por ponto de alta precisão utilizando o GPS: Uma solução para a geodinâmica
(2000-03-01)
Point positioning from GPS data can provide precision varying from 100 meters to a few millimeters at the level of 95% probability. To reach the best level of accuracy, users need proper equipment and software, as well as ...
PPP em tempo real com estimativa das correções dos relógios dos satélites no contexto de rede GNSS
(Universidade Estadual Paulista (Unesp), 2012-04-26)
Dentre os diversos métodos possíveis de posicionamento GNSS, encontra-se atualmente em evidência aqueles que proporcionam posicionamento em tempo real (ou próximo do tempo real) com acurácia ao nível centimétrico ou ...

Ionospheric tomographic common clock model of undifferenced uncombined GNSS measurements
(Springer, 2021-10-13)
In this manuscript, we introduce the Ionospheric Tomographic Common Clock (ITCC) model of undifferenced uncombined GNSS measurements. It is intended for improving the Wide Area precise positioning in a consistent and simple ...
Postprocessing synchronization of a laser scanning system aboard a UAV
(2019-10-01)
Synchronization of airborne laser scanning devices is a critical process that directly affects data accuracy. This process can be more challenging with low-cost airborne laser scanning (ALS) systems because some device ...
