GPS positioning simulator is widely used in the research, development, production and testing of equipment. This article mainly introduces how to use GPS positioning simulator.

The GPS simulator is mainly applied to ranging accuracy test, navigation message test, lost lock reload test, positioning accuracy test, speed accuracy test, channel delay test, conformance test, bit error rate test and so on, which will greatly enhance the work efficiency.

There are 4 main functions: static (fixed point) trajectory making, dynamic trajectory making, track signal sending and real-time track recording. The real-time track recording requires the equipment to track the scene at the scene. Commonly used in the transmission of the trajectory signal in the circular transmission function.

After receiving the location simulator, there is no problem in checking the appearance of the package, so it can be tested and used. After power supply, turn on the device desktop and turn on the GPS signal simulator software. Click on the "track to send" button, then click the "open" button to see the txt test file in the directory, select one of the tracks to "open", click the "single track" button, and wait for a few seconds or more than ten seconds to have 2 black command Windows pop-up, representing the successful launch of analog signal.

When the factory is out of factory, it will have several test trajectories, static and dynamic trajectories, and a single track time with a few minutes of 20 minutes and about one hour for users to test. If you purchase the GPS simulator just to solve the GPS signal problem, let the simulator launch the GPS signal, directly using any built-in track can be completed.

The cycle of sending loops is equivalent to relocation. In actual circular transmission, there will be 1 to 2S neutral periods in every two runs, for example, when the current running track is 60s, when 61S is switched, it will be repositioned.Normal is not felt, according to project needs, such as mind can be directly recordings longer longer track.

Some of the client devices are saved by ephemeris. When receiving the GPS simulator signal, there must be a sequence. It is recommended that the SYN5203 GPS signal simulator run first and then turn on all the receiving devices.

If the signal of the simulator is interfered with the normal work of the surrounding equipment, then the signal radiation range needs to be narrowed. It can also increase the signal attenuator connected to the simulator output interface. This solves the problem that the signal is too strong to interfere with other peripheral work.

When a device with more than one device is required to receive the simulator signal directly, it is recommended to match the signal distributor. The interface of the broadcasting signal of the satellite signal simulator is SMA, and the input interface of the distributor is BNC, and it can be connected with a SMA to BNC cable.

The SYN5203 positioning simulator can output all statements of the receiver, and the receiver in use is unable to distinguish the simulated satellite signal and the real signal. If the receiving device has ephemeris preservation, it must have a priority in receiving the simulator signal. The simulator needs to be run first and then all the receiving devices will be switched on.
