Abstract
Techniques for transmitting global navigation satellite system (GNSS) correction data to a rover. GNSS signals are wirelessly received by a base station from one or more GNSS satellites. GNSS correction data is generated by the base station based on the GNSS signals. A beacon frame is formed by the base station to include a frame header, a frame body, and a frame check sequence (FCS). The frame body is formed to include the GNSS correction data. The beacon frame is wirelessly transmitted by the base station for receipt by the rover. The rover wirelessly receives the beacon frame. The GNSS correction data is extracted by the rover from the beacon frame. A geospatial position of the rover is calculated based on the GNSS correction data.
