NS8350 Series Navigation Signal Source

The NS8350 series navigation signal source supports signal simulation of four satellite navigation systems, BDS/GPS/GLONASS/GALILEO, providing users with stable, reliable, accurate, and controllable GNSS simulation signals. It is a dedicated testing equipment for satellite navigation product development, testing, and certification. After selecting the relevant components, the NS8350 series navigation signal source can support signal simulation for special applications such as INS/GNSS combination, multiple antennas, and multiple users.
