Research on the Production of the Carrier Moving Trajectory of High Dynamic GPS Signal Simulator
Huanhuan Ma, Yubai Li · 2012
High dynamic GPS signal simulator is an indispensable instrument for the testing of high dynamic GPS receivers. The high dynamic GPS signal simulator consists of hardware, computer and software. The software comprises the error simulation models, the carrier moving trajectory simulation models and the satellite navigation parameters, etc. The carrier moving trajectory simulation models is a key technique that the high dynamic GPS signal simulator must solve. The carriers are divided into satellites, missiles, airplanes, ships and automobiles. The target trajectory simulation models are set up respectively according to their moving rules. In order to get the convenience to users, as long as a user inputs proper parameters, the carrier moving trajectory can be generated automatically by the simulator.
