摘要
载体轨迹仿真是卫星导航信号模拟器的主要功能之一。针对载体轨迹仿真的特点,通过分析载体相对地球的运动方程,建立了依据载体预设运动方案,获取运动过程中任一时刻载体的位置、速度、加速度和加加速度等信息的仿真模型。实验结果与Spirent公司SimGEN卫星导航信号模拟系统产生的载体轨迹仿真数据有很好的一致性。
The simulation of carrier track is an important function of satellite navigation signal simulator. Based on the char-acteristics of track simulation, the motion equations of carrier with respect to the earth are analyzed, and the simulation model is established. With this model, position, velocity, acceleration and jerk at anytime from the prearranged motion can be obtained. The result agree with the simulation data of Spiren SimGEM simulator.
