The GPS trajectory simulator should have complete civil signal support capability, suitable for the development, production, testing and verification of all kinds of civil navigation terminals.

The GPS trajectory simulator is equipped with an inertial navigation simulation module, which simulates satellite navigation signals and inertial navigation simulation signals at the same time, and is used for R & D, generation and verification of integrated navigation receiving.

The GPS trajectory simulator can also be equipped with a test and evaluation software system, which can real-time test and report generation for the positioning, testing, timing, sensitivity and first positioning time of the receiver, so as to realize the automatic test of unattended.

The GPS simulator can simulate the timing signal of GPS positioning at the same time, which is used for R & D, generation and verification of integrated navigation receiving. At the same time, the test and evaluation software system is also selected to carry out real-time test and report generation for positioning, testing, time service, sensitivity and movement track of the receiver of ship navigation, so as to realize automatic test without person on duty.

The SYN5203 GPS signal simulator is a radio frequency simulation signal output that supports GPS L1 frequency points, supports various trajectory outputs of different time lengths, supports real-time ephemeris and external ephemeris parameter input, and can meet the test requirements of all kinds of GPS navigation time service receiving terminal, and can replace the foreign high GPS simulator.

Ten advantages of using GPS trajectory simulator are:

1, by using the GPS simulator, there is no error in the satellite clock. Unless you want it to exist, and whether it exists or not, you can accurately understand them and implement them at a known time.

2. Using the GPS simulator, we can eliminate all the orbital errors, and use the "perfect" star group, or we can achieve fully quantifiable errors in a controlled way.

3. It is impossible to have navigation data errors when using the GPS simulator, unless it is deliberately applied.

4, the use of GPS simulator can completely avoid the impact of the atmosphere, thereby eliminating these errors. On the contrary, we can apply these errors to the known models and record them comprehensively.

The GPS simulator can use multipath models to multipath signals.

The GPS track simulator itself does not have any wireless signal interference, but it can also simulate interference if necessary.

7. Using the GPS trajectory simulator, the signals generated each time are the same. The scene will start at the same time at the same date, and the position of the satellite will be the same, even the relative phase shift between different signals is the same.

8, when using real GPS satellite test, there is no preset factor. In addition to testing the physical location and height of the positioning antenna, other factors are not within the control area. It is impossible to let time roll back, disable the atmosphere, adjust satellite signals, errors, data and tracks - all of which are exactly what you need to control completely.
