High dynamic global positioning system receiver

摘要: A GPS receiver having a number of channels, one for each plurality satellites, receives an aggregate pseudorange code time division modulated signals from some or all satellites and converts the to baseband then digital form separate processing in which includes complex mixer adjustment signal smooth estimate frequency, ω, next measurement interval, N-lag cross correlator replica adjusted smoothed (delay), τ. fast Fourier transform processor computes energy as function Doppler frequency correlation lag, range estimator estimates pseudorange, τ, ω. These raw channels are used position, velocity, clock offset rate conventional navigation control unit, based on total solution, that unit estimates, τ interval. The thus not just without use any phase-locked loop.
