Functional Description
GNSSRK-M-RDV4 series of GNSS full-band repeater system, leading the outdoor full-band navigation satellite signals to the indoor, tunnels, subways, mines, or other places where satellite signals cannot be reached, to finish all the positioning and timing tasks and tests indoors instead of outdoors.
GNSSRK-M-RDV4 is a four point GNSS Repeater, re-adiating GNSS signal. This solution offer adjusiable test signal to receiver. If need extend the system, you can add assemblies and sending antennas. so as to cover satelite sional indoor aroe area and more rooms or buidinos
The GNSSRK serial is one of the indoor GPS coverage solutions from GEMS-Navigation.

Typical Faults and Solutions
Typical faults and solutions
GNSS repeater/GPS booster/GPS signal amplifier GNSSRK-M-RDV fault location and remove:
First: To determine whether the RGA30-DV power supply connected, through the RGA30-DV digital display can be observed to lose whether there is voltage output, such as digital display shows a voltage of about 5V, indicating normal power supply, RGA30-DV work properly. Otherwise, check the power outlet for good contact.
Second: If the digital stepper is adjustable, the input port of the amplifier has a voltage of 5V, you need to check whether the fixing is steady between GRA10 and the cable.
Third: If the below two step were ok, please check the outdoor antenna S440 .You can, check the voltage between axis of the cable connector and the outer shielding layer to make sure it’s 5V.If no voltage, the circuit has fault, please contact our technical support. If 5V,the antenna S440 can be suspected.(In fact, this case hasn’t appear in our engineering projects.
