Abstract

The invention provides a method and a device for generating an ephemeris message of a GLONASS satellite signal and belongs to the field of satellite navigation simulation. The method comprises the steps of: obtaining analogue simulation time; determining the position, the speed and the acceleration of a satellite in a GLONASS satellite system according to the analogue simulation time and global positioning system (GPS) ephemeris orbit parameter description method, and converting the analogue simulation time and the position, the speed and the acceleration of the satellite into a GLONASS space-time system from a GPS space-time system to obtain the ephemeris message of the GLONASS satellite signal. By the method, the message of the GLONASS satellite signal can be simulated under the situation that the ephemeris message of the GLONASS satellite system cannot be obtained, so that the data and simulation environments are possibly provided for research development and test of a receiver by simulating the GLONASS satellite signal.
