VERIPOS, a leading global provider of precise satellite positioning solutions to the international offshore and marine industries, is concluding the upgrade of its entire global network of GNSS reference stations with high performance multi‑frequency GPS/GLONASS/Galileo/BeiDou receivers from Septentrio. VERIPOS owns and operates a network of over 80 reference stations worldwide that is used to determine estimates of the orbit and clock errors of multiple GNSS satellite constellations. VERIPOS uses these estimates to calculate corrections which are then broadcast to end users to significantly improve the accuracy of positioning. At the heart of the network is Septentrio PolaRx4, a fully featured reference receiver that provides high-quality tracking and measurement of all available and upcoming GNSS signals.
