Phase Ambiguity Resolution Method for a Satellite Based Positioning System

摘要

The invention relates to a satellite-based positioning system in which a transmitter (2) emits electromagnetic radiation at least at N≧3 carrier frequencies (3, 4, 5). In order to resolve the phase ambiguity for said satellite-based positioning system, the electromagnetic radiation is received by a receiver (1), and K pseudo paths (3a, 4a, 5a, 6a) and L carrier phases (3b, 4b, 5b, 6b), especially at least two pseudo paths (3a, 5a) and at least two carrier phases (3b, 4b), are derived from the received radiation as M pieces of distance data, wherein M=K+L. In order to determine the position, the integer phase ambiguity is derived from the linear combination of a maximum of M≦2N−1 pieces of distance data.
