Technology Overview
To provide precise positioning accuracy, a GNSS receiver needs to compensate for inaccuracies by satellite constellations, receiver hardware, and atmospheric conditions. These inaccuracies can be calculated by a network of fixed reference stations that constantly receive GNSS data.
This correction information is then broadcast to GNSS receivers as a correction service. Topnet Live is Topcon's GNSS correction service and consists of the reference station network, the correction calculation software, and the correction broadcast service.
