Influência do acréscimo de satélites glonass sobre a qualidade de coordenadas estimadas com satélites GPS em local de difícil rastreio
Nobre, Tiago de Carvalho
From estimate coordinates point through the use of GPS satellites constellation, located in difficult tracing GPS signs place, by means of using coordinated procedures of transport with the use of receiving devices with double frequency signals satellites, referring to the Brazilian Geodetic System (SGB), it was evaluated the influence of the addition of GLONASS constellation on these coordinates, with signals caught for the same receivers and treated in afterprocessing specific software. The addition of GLONASS´s data indicated an improvement in the accuracy’s quality and the reduction of the values of PDOP of these observations.
