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

The gps trajectory simulator is equipped with inertial navigation simulation components, which can simulate satellite navigation signals and inertial navigation simulation signals at the same time, which can be used for the development, generation and verification of integrated navigation reception.

The gps trajectory simulator can also be equipped with a test and evaluation software system, which can real-time test and generate reports on 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 GPS positioning timing signal at the same time, which can be used for the development, generation and verification of integrated navigation reception. At the same time, it is also equipped with a test and evaluation software system, which can real-time test and generate reports on the positioning, testing, timing, sensitivity and motion trajectory of the receiver of shipborne navigation, so as to realize the automatic test of unattended.

SYN5203 GPS signal simulator supports RF simulation signal output of GPS L1 frequency point, supports various track outputs of different time lengths, supports real-time ephemeris and external ephemeris parameter input, can meet the test requirements of all kinds of GPS navigation timing receiving terminals, and can replace foreign expensive GPS simulators.

Ten benefits of using the gps trajectory Simulator:

1. By using the gps simulator, satellite clocks are error-free unless you want them to exist, and whether they exist or not, you can accurately understand them and implement them at a known time.

2. Using the gps simulator, you can eliminate all orbital errors that will occur, and use "perfect" star clusters, and completely quantifiable errors can also be achieved in a controlled way.

3. Navigation data errors can not occur when using gps simulator, unless it is imposed on purpose.

4. Using the gps simulator, we can completely avoid the effects of the atmosphere, thus eliminating these errors. On the contrary, we can also impose these errors on known models and fully record them.

5. Gps simulator can use various multipath models to apply multipath to the signal.

6. There is no wireless signal interference in the gps trajectory simulator itself, but it can also be simulated if necessary.

7. Using gps trajectory simulator, the signal generated each time is exactly the same. The scene will start at the same time on the same date, and the position of the satellite will be the same, even the relative phase offset between different signals will be the same.

8. When testing with a real GPS satellite, there is no preset factor. Except for testing the physical position and height of the timing positioning antenna, other factors are not within the control range. It's impossible to roll back time, disable the atmosphere, adjust satellite signals, errors, data, orbits-all of which is exactly what you need complete control over.
