  • Functional Description

    GNSSRK-M-RDV4 is a repeater operaters by receiving ful-band GNSS satelite signal with an antenna located outside the building and re-radiatig the signals into theindoor area or covered space where satellite signal cannot reach.

    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.
