ABSTRACT:
A method of, apparatus for, and computer-readable medium for rapid, real time kinematics determination requiring lowered information transmission for position updates than traditional RTK systems. Position signals are received from a base station and roving system and a compressed position signal is received from the base station. A position estimate using an integrated method is determined using the received position signals from the base station and the roving system and the compressed position signal from the base station. Ambiguity resolution of the position estimate is enhanced by applying a quality control procedure using derived validation criteria. A second position estimate is derived based on the enhanced ambiguity resolution. Because of the use of the compressed position signal smaller transmissions may be performed at a more rapid rate providing a higher position update rate.
