The GPS signal simulator was successfully put into operation in a shipping company in Zhejiang. It provides an optional inertial navigation simulation module for the shipping company. It can simulate the timing signal of GPS positioning at the same time, and 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 simulator can accurately and accurately simulate the timing information of GPS satellite navigation. It can send location timing information to support real-time ephemeris and external ephemeris parameter input, and it can meet the testing requirements of all kinds of GPS navigator terminals.

Ten advantages of using GPS signal simulator are:

1, by using the satellite 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 simulator can eliminate all the orbital errors, and use the "perfect" star group, or achieve fully quantifiable errors in a controlled way.

3. It is impossible to have navigation data errors in the simulator unless it is deliberately applied.

4, using simulators can completely avoid the effects of the atmosphere and eliminate these errors. On the contrary, we can apply these errors to the known models and record them comprehensively.

The simulator can eliminate the multipath of the GPS satellite signal, or multipath model can be applied to the signal.

The simulator itself does not contain any interference from wireless signals, but it can also simulate interference if necessary.

7, using simulators, 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.

9, the two factor closely related to accuracy is quality and reliability. The precise engineering in the design and construction of the simulator and the quality control process of these technical categories will ensure that the equipment can provide reliable services over the years.

10, the simulator can absolutely control the intensity and time of the satellite signal, and add or delete a single source of injury at will.
