This paper mainly introduces the performance and function of the satellite simulator, and points out the superiority of the satellite simulator in the future social application. Because of its own characteristics, it will be widely applied in many future scenarios.

Satellite simulator mainly includes simulator of GPS, Beidou, GLONASS and Galilean satellites. The satellite simulator mean GPS satellite simulator described in this paper is a simulation device simulating the navigation signal of GPS navigation and positioning system based on GPS satellite signal.

The satellite signal simulator is based on the real satellite's trajectory and navigation information. It simulates the information path of the satellite signal in real time. The use of satellite simulator in real environment has extremely prominent advantages: it can customize the selection of test scenarios, simulate the conditions of the satellite navigation system at any time and place in the laboratory or under certain conditions; it can control and test the navigation satellite signals, delay, receiving altitude angle, direction angle and other satellite signal navigation characteristics over time, and can be tested. There is no difference in repeatability between the satellite signal simulator and the real satellite signal, that is, all the test scenarios can be tested repeatedly under the same custom scenario environment.

With the growth of the demand for high-precision synchronous applications in all walks of life, a satellite signal simulator satisfying the practical test is more urgent. Under the real satellite environment, the number of navigation satellites depends on the time chosen by the tester, geographical location, environmental occlusion and other conditions which can not be controlled, which can not be controlled by the tester, but not in many similar ways. Under the conditions, it satisfies the test of the real environment, showing the schematic diagram of the real time trajectory recording of the satellite signal simulator.

The satellite signal simulator can simulate any time, place, and visibility of all kinds of navigation satellites under the open sky condition. The navigation satellite test signal environment can be used to meet the environmental requirements of the test scenarios and practical experiments according to the requirements of the use, and can also select and real-time change the satellite environment for more test functions.

As a satellite signal simulation test equipment, the satellite signal simulator can also be used to test the satellite timing receiver. It plays a crucial role in many aspects of production and evaluation, such as test scenarios and test items which can not rely on real satellite environment.

Satellite simulator relies on its practical and convenient characteristics, widely used in sharing bicycle, sharing vehicle, navigation and positioning equipment, electronic fence equipment and other test application environment. It is used for verification test functions under specific conditions, and plays an irreplaceable role in modern society.
