The invention discloses a
simulation method for high dynamic multi-mode
satellite navigation
signal source and a device thereof, wherein, the high dynamic multi-
modal satellite navigation
signal source can simulate
satellite signals of the following three systems: Global Position
Satellite system, global navigation
satellite system and second-generation Beidou
satellite navigation system in space, and the satellite signals are received by a dynamic navigation
receiver; the
signal resource can simulate the moving state of a user
receiver, imitate the error of satellite signals caused in the course of transmission and produce three-mode satellite signals in real time. In the embodiment, the device consists of a
user interface module, a control module, a satellite parameter calculation module, a satellite signal producing module, an
output device and a data receiving and analysis module. The device simulates simultaneously three-mode satellite signals to accelerate the research of multi-mode navigation
receiver. By using an inner fumitoshi interpolation method, the device saves calculation resources and improves interpolation accuracy. By using a parametric design, the device can improve the reusable ability of modules and aim at different
satellite navigation systems to implement convenient transformation.
