Integration of a regional GPS network within ITRF using precise point positioning
GPS precise point positioning (PPP) can provide high precision 3-D coordinates. Combined pseudorange and carrier phase observables, precise ephemeris and satellite clock corrections, together with data from dual frequency ...
Posicionamento por ponto de alta precisão utilizando o GPS: Uma solução para a geodinâmica
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 ...
Accuracy assessment of Precise Point Positioning with multi-constellation GNSS data under ionospheric scintillation effects
GPS and GLONASS are currently the Global Navigation Satellite Systems (GNSS) with full operational capacity. The integration of GPS, GLONASS and future GNSS constellations can provide better accuracy and more reliability ...
CIGALA: Challenging the solar maximum in Brazil with PolaRxS
The upcoming solar maximum, which is expected to reach its peak around May 2013, occurs at a time when our reliance on high-precision GNSS has reached unprecedented proportions. The perturbations of the ionosphere caused ...
Mitigating systematic errors for single frequency GPS receivers employing a penalized least squares methodology
Among the positioning systems that compose GNSS (Global Navigation Satellite System), GPS has the capability of providing low, medium and high precision positioning data. However, GPS observables may be subject to many ...
High precision GPS network with precise ephemerides and earth body tide model
(Sociedade Brasileira de Geofísica, 1997-07-01)
A rede GPS do IGS (International GPS Service for Geodynamics) proporciona uma série de dados GPS global preciso, os quais são de grande valor para o desenvolvimento de algoritmos e programas computacionais para posicionamento ...
