The GPS signal simulator is a signal generator for GPS satellite navigation timing simulation, simulating the navigation signal of the GPS satellite navigation and positioning system, and exporting the satellite reference information through the radio frequency simulation signal of the standard GPS L1 frequency.

In this paper, we mainly introduce the SYN5203 GPS signal simulator, a GPS signal transmitter based on GPS signal benchmark, which meets the needs of basic and timing user equipment. It can complete the Beijing Opera accuracy test, navigation message test, lock out re capture test, location accuracy test, speed accuracy test, channel delay test, conformance test, bit error rate test and so on.

GPS signal generator in the simulation of GPS signal, with real-time ephemeris and external ephemeris parameter input, different time length of the trajectory output to meet the GPS navigation receiving terminal test requirements, its main application function selection design is divided into four kinds: real-time trajectory recording, static trajectory production, dynamic trajectory production, track signal transmission.

The real-time track record of this GPS signal generator is similar to the real time recording function of the signal generator in the market. Under dynamic operation, the display track of the device is exactly the same as the actual operation trajectory in the satellite positioning selection, and the operation position is related to the set longitude and latitude.

GPS signal generator static trajectory production is in static state of operation can choose to input the longitude and latitude information, time and other information to form specific information simulation, generate corresponding files to complete. This kind of static trajectory production is more convenient and faster than the signal simulator in the market.

GPS signal generator generator dynamic trajectory production, through map selection path, edit dynamic trajectory and so on to complete the dynamic trajectory production link. Compared to the signal generator on the market, it has GA navigation file conversion, ECEF coordinate file conversion, GGAtxt conversion to ECEF conversion, and KML or txt files can be selected on the text presentation. It is a relatively complete simulation path preservation function in the market, and is suitable for a variety of needs.

The signal transmission of the GPS signal generator is to transmit the saved or original track production document, and receive the link signal through the form of mobile phone or PC. The operation is convenient, and the high frequency analog signal source can be generated.

The GPS signal generator can meet the testing requirements of all kinds of GPS navigation time service receiving terminals, and is suitable for the research and development of related products that rely on satellite navigation and positioning functions, such as sharing bicycles, sharing cars, navigation positioning equipment, electronic fence equipment and other application environments. It can greatly improve efficiency and avoid frequent field testing, greatly improving the speed of product development and testing deployment.

The design of the GPS signal generator is based on the PC system, the design of the panel external screen, the coexistence of the power supply and the built-in power of the device. The display is clear and complete, and can replace the high GPS simulator abroad. If there is a demand for this equipment, you can consult our company's business people!
