The GNSSRK-D-RDV system guides outdoor GPS and Beidou signals to places where indoors or other satellite signals cannot bereached. Various tests that should be done outdoors can be completed indoors. GNSSRK-D-RDV is a multi-point GPS and Beidou signal forwarding system, that is, multiple transmitting antennas forward GPS and Beidou signal signals. This solution can provide adjustable test signals for the receiver. If users need to expand on this system, they can use multi-system receiving antennas and transmitting antennas, which can support multi-system multi-band satellite signal reception and forwarding to achieve the purpose of indoor satellite signal coverage. System multi-band satellite signal reception and forwarding, To achieve the purpose of indoor satellite signal coverage.
