The signal channel is a circuit combining hardware and software, and it is the core part of the receiver. Its function is to search, pull and track satellites, despread and demodulate the broadcast message signal into a broadcast message, perform pseudorange measurement, carrier phase measurement and other functions. Puller frequency shift measurement. The memory is used to store the satellite ephemeris, satellite almanac, code phase pseudorange observations collected by the receiver, carrier phase observations and Doppler frequency shift once an hour.
