| Abstract: | For the purpose of testing the performances of Global positioning system(GPS) receivers in movement patterns of a wide range and high-fidelity environments,high dynamic GPS signal simulators are designed based on computing the Doppler frequency of the simulation of carrier and code and the delay of satellite signals by using existing ephemeris and users-set parameters,which are simulated in the environment of FPGA and DSP.The simulated signal is processed by GPS receivers,positioning results compared with t... |
