Abstract

The invention relates to a recording-type satellite signal simulation method. According to the method provided by the invention, a navigation technology and a recording technology are combined, and satellite signals are stored in advance and are monitored so as to ensure that the stored satellite signals meet the requirements. When satellite receiving equipment is required to be tested, the recorded satellite signals are played back and are monitored so as to ensure that the radio-frequency transmitted satellite signals meet the testing requirements. A satellite signal simulator realized by adopting the method can play back the stored satellite signals without time limitations. In this way, when the satellite receiving equipment is required to be tested, only the stored satellite signals are played back, the corresponding testing work can be carried out, therefore the convenience and quickness of the testing work and the electromagnetic safety are ensured.

Description

technical field [0001] The invention relates to a method for simulating satellite signals, in particular to a method for simulating satellite signals by combining navigation and recording technologies, and belongs to the technical field of communication. Background technique [0002] The routine testing of traditional satellite receiving equipment (such as GPS / GLONASS / BD receivers) is done by erecting antennas, laying long cables, and adding signal amplifiers between cables. The test work is affected by the weather and satellite reception conditions, so the test work has poor mobility and low efficiency, and the electromagnetic safety of the target cannot be guaranteed. The United States has developed a satellite signal simulator based on satellite modeling methods, but due to confidentiality reasons, the specific principles of this satellite signal simulation method cannot be obtained from open literature. Contents of the invention [0003] The technical problem of the p...
