摘要： A method of and computer-readable medium containing instructions for high accuracy, reliable position determination. A high precision GPS-RTK system using the present novel techniques is initialized instantaneously or near instantaneously. To improve the computational efficiency and to improve the reliability of the procedure, advances in data functional and stochastic modeling, validation criteria, adaptation and system design were achieved. A position estimate using an integrated method is determined. Ambiguity resolution of the position estimate is enhanced by applying a quality control procedure using derived validation criteria. A second position estimate based on the enhanced ambiguity resolution is derived.

摘要： 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.
