Our purpose is to calibrate the Javad receiver.
We have the GNSS receivers that use Javad chip inside. We don't know the Javad chip series inside receiver because the original prohibits us to open them.
Our Javad receivers can receive GPS L1/L2, GLONASS.
We would like to test them in lab by simulating the signal with vector signal generator. The signal of simulation can be easily acquired by ordinary handheld Garmin .
While the Javad only viewed but not acquired or locked the satellites. The Javad still works well in all conditions except in simulation lab.
If someone in this forum faced the problem like us, please let us know about the requirement of Javad´s receiver chip. The difference between the ordinary handheld GPS receiver and Javad receiver which we can config the vector signal generator to send the proper signal that Javad receiver can acquire not only view.
Thanks
