Our GPS signal simulator has been put into the test of sharing the automobile market manufacturers, and has successfully invested in a large number of test application scenarios. This article mainly talks about the function embodiment of GPS signal simulator in sharing automobile market, and makes a brief analysis of the application scenario of GPS signal simulator, hoping to provide a relative reference system for users who have needs in the shared market.

The GPS signal simulator, as the name implies, is a simulation device for GPS satellite signals. It is a real-time navigation path generated by real-time satellite monitoring, or manually set up manually to generate the navigation path signal path under the custom requirement scenario, and to get the satellite simulation navigation path signal through different ways, and send it through the GPS signal simulator itself. The real-time running environment enables the device that needs to be tested in a specific environment to obtain the navigation signal path in the various test environments that are customizable.

The sharing market is a new economic mode rising in China in recent years. It mainly relies on the rapid development of Internet technology as a media system. It is a new economic mode based on strangers and the temporary transfer of the right to the use of goods. The rise of the shared market has enabled more people to enjoy fairly fair social resources, and to pay and benefit in different ways, so as to get the economic dividends they can enjoy. With the sharing market being recognized by more and more young people, car sharing has also become a new way of car use, which can be booked directly by means of mobile phones, which is more convenient than traditional car rental.

Vehicle sharing units need to do a comprehensive test of cars before they put large numbers of vehicles into different parts of the region. Especially, this kind of service leased by self service car has more stringent requirements for vehicle positioning system, navigation path and so on. At the same time, more accurate reliability testing is required in vehicle performance testing. However, when the vehicle performs its performance test in the plant, the real-time satellite environment can not guarantee the accuracy and repeatability of the test. At this point, the GPS signal simulator must be involved before the test of the shared vehicle can be completed.

The GPS signal simulator is mainly applied to the performance test of the automobile factory when testing the shared vehicle. When the vehicle is out of factory, it needs to navigate and test in a certain way. The GPS signal simulator is set up according to the track track of all the cars prefabricated by the automobile manufacturer. After recording, the satellite navigation signal path can be circularly played to achieve the performance test of the vehicle on the fixed line.

The GPS signal simulator simulates the navigation signal path to simulate the real GPS signal, which fully meets the test standard error caused by the real-time satellite's unpredictable condition. The GPS signal simulator can preset a number of tracks. The dynamic trajectory can set parameters such as speed, acceleration and acceleration. It has been widely applied in the shared market.
