[Product Introduction and Use]
Beidou satellite signal purification and forwarding equipment is mainly used for indoor joint debugging and testing of anti-interference Beidou receivers. Ordinary satellite signal repeaters cannot meet the test requirements when testing anti-interference Beidou receivers indoors.
Beidou satellite signal purification and forwarding equipment has the functions of purification and direct forwarding, and users can switch working modes freely. The equipment realizes the demodulation, message recovery, message re-spreading, signal modulation, frequency conversion transmission and other processes of satellite signals at various frequencies of the Beidou satellite system, and realizes signal forwarding without losing the signal-to-noise ratio.
Beidou satellite signal purification and forwarding equipment can effectively solve the problem of indoor testing of anti-interference receivers, can better match the system use, and ensure system reliability.
