The SYN5203 GPS simulator can accurately and accurately simulate the timing information of GPS satellite navigation. It can send location timing information to support real-time ephemeris and external ephemeris parameter input, and it can meet the testing requirements of all kinds of GPS navigator terminals.

The GPS signal generator can simulate the number of satellites to 16, normally 10-12. The GPS signal simulator outputs the real GPS signal, and all the statements received by the receiver can output. In the application, the receiver can not distinguish our signals from real signals.

There are 4 main functions: static (fixed point) trajectory making, dynamic trajectory making, track signal sending and real-time track recording. In real time, track record is recorded in the place where the simulated trajectory is needed. It can also be understood as the recording and playback process.

After careful analysis, the recording function of the GPS signal generator is as follows: realizing the map function of the page, including simple map scaling, translation, drag and drop, 2D/3D map switching, satellite map marking, and marking and querying of a certain location within the scope. Realize the bus navigation, input the starting point position, display the navigation line on the display, display the transfer plan, realize a query function of a line, input a certain line, inquire about the site information of the line, wait for the vehicle and jam and information, display the running track of the vehicle, query the GPS data of a bus, and show the state and dynamics of the vehicle. To track the current location information of a bus and display it on the map; to inquire about the running track of a certain vehicle, enter the license plate number, and dynamically display the track of the vehicle in a certain time period on the map.

The SYN5203 GPS signal generator indicates that the coverage range is 10 thousand square meters, and the radius is within 100 meters. It can connect all GPS receivers in the range he sends. If you need to narrow the analog GPS signal radiation range and prevent the signal intensity from being too large to interfere with other peripheral devices, it is recommended that direct connection and direct connection signal be relatively weak, and signal attenuators can be added to the simulator output interface.

The temperature compensation crystal oscillator of the satellite simulator can be externally connected with a constant temperature crystal oscillator. When the built-in temperature compensation crystal oscillator is used, the positioning accuracy of the signal accuracy is less than 5 meters. When the external constant temperature crystal oscillator is positioned, the positioning accuracy is less than 1 meters, and the speed accuracy of the signal accuracy is less than 0.1m/s. When the track is recorded, the vehicle antenna with external SMA interface is required, the positioning accuracy is 2.5 m CEP, and the speed accuracy is 0.1m/s.

The device supports ephemeris input. In practical applications, the receiver of the client is unable to distinguish the signals and real signals provided by the GPS simulator, because all statements received by the receiver can be output.
