Description
The GNSSRK serial GPS Repeater kit is a far forward gps signal amplifier unit.
The GNSSRK-M-DV system receiving GNSS band signal, include: GPS/GLONASS/Beidou/Galieo/RNSS/QZSS/SBASNAIC/OmniStar are led indoors or other places thatcannot be reached by satelite signals. Various tests that should be done outdoors can be completed indoors GNSSRK--DV is a set of mulf-system and ful-bandsatelite model transponder kts, that is, a transmiting antenna to fonward sateite signals. This solution can provide adjustable test sionals for the receiver.If users need to expand on this system they can use muli-system eceiving antemnas and transmiting antennas to support mult-system and muli-band satelite signareception and forwarding to achieve indoor satellite sinal coverage.

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.
