Shows the method for positioning depending on four satellites.

APOS stands for Austrian POsitioning Service and is the Multi-GNSS positioning service of the BEV - Federal Office of Metrology and Surveying. The GNSS signals (GPS, GLONASS and GALILEO) are processed and – to improve the accuracy of the satellite based measurements – the derived parameters are provided.

The cooperation with all neighbouring surveying authorities guarantees the involvement of many international GNSS reference stations close to the Austrian boundary. Thus APOS is the positioning service for Austria because it offers homogeneous 3D-coordinates in ETRS89 nation wide and across boundaries.
