With the development of science and technology in recent years, satellite navigation technology is developing and maturing, and has been widely applied in different fields. Especially in the development and testing phase of the navigation and positioning receiver, GPS signal simulator is needed to simulate different environments and quantitative evaluation, and the GPS simulator must be precise enough to ensure the accuracy of the numerical value. Therefore, the success of the simulator is of great significance.

The GPS signal simulator can simulate the trajectory of satellite signals and simulate the navigation signals of GPS satellite navigation system. It can simulate the movement state of the navigation terminal at any time and any position, and can also conduct navigation terminal test in static, low dynamic and high dynamic environments. The SYN5203GPS signal simulator can provide high efficiency and high stability testing methods for GPS receivers and equipment using GPS system. SYN5203GPS signal simulator is used to provide models for related products, such as vehicle navigation, testing, satellite motion, navigation and positioning equipment, electronic fence equipment, vehicle mounted equipment and other equipment requiring GPS satellite signals.

The GPS signal simulator can simulate real GPS satellite signals and provide batch automatic testing and testing for satellite navigation user equipment. The SYN5203GPS signal simulator receives the satellite signal and location through receiving the machine. Then the SYN5203GPS signal simulator carries out the track recording. After recording, the file is saved, and the satellite navigation equipment is connected with the signal sent by the GPS signal simulator. At this time, the satellite navigation equipment works according to the track and location information of the GPS signal simulator. The SYN5203GPS signal simulator can record the trajectory in real time and record the track in real time according to the current time and environment, and can modify the date and time. Dynamic trajectory production can modify maximum longitudinal acceleration, maximum additional speed, maximum lateral acceleration, maximum acceleration, start stop time and end residence time. The transmission of track signals can play track, cycle track, static track production and so on.

The GPS signal simulator can simulate the satellite signal received by the carrier according to the motion state of the carrier, and is used to measure the acquisition, tracking and positioning accuracy of the receiver, providing the conditions for the development of the GPS receiver and the application of the new technology of the GPS navigation equipment. The GPS signal simulator can be used to measure the receiver's accuracy. At present, the traditional GPS hardware signal simulator function is not easy to expand, and the SYN5203GPS signal simulator produced by Xi'an synchronous Electronic Technology Co., Ltd. can meet the testing needs of all kinds of GPS navigation receiving and receiving terminal. It can replace the foreign high GPS simulator, and it can be widely used in satellite navigation equipment, shared vehicle, navigation and positioning equipment, electronic fence equipment, vehicle, testing, etc. Industry.
