ABSTRACT:
A method and system for variable data rate transmission in a real-time kinematic (RTK) positioning system. An RTK positioning system having a reference station and a rover utilizes wireless communications for data transfer. The data transmission rate between the reference station and the rover is dynamically controlled by a programmable transmission controller. The transmission rate is determined on the basis of specific parameters. Parameters that may be used to determine the data transmission rate include rover demand, required rover accuracy, satellite positioning system (SATPS) events, the required data for ambiguities, and the type and content of the data transmitted.
