摘要：

The invention belongs to the field of radio navigation location technology and especially relates to a Beidou terminal signal receiving and processing device and method. The device includes an antenna unit, a radio frequency unit, a baseband signal processing unit, an information processing unit, a power unit and a display control unit connected successively. The method includes capturing fake satellites and satellites respectively by adopting a storage-based baseband capturing method; receiving fake satellite signals and real satellite signals for fake satellite and satellite information decoding; performing updating operation on extracted navigation parameters; extracting carrier phase, code phase and Doppler observation information and performing calculation on location, speed measurement and time service. According to the invention, by the design of an integrated antenna receiving the satellite signals and the fake satellite signals and a radio frequency front end and with the adoption of an algorithm realizing seamless positioning depending on independent positioning and compatible positioning for solving a problem of near-far effect of the two kinds of signals, constellation geometric structure is improved and user positioning precision is improved.
