GNSSRK-4 is a repeater operates by receiving GPS/GLONASS/Beidou2/Galileo satellite signals with an antenna located outside the building and re-radiating the signals into the indoor area or covered space where satellite signal cannot reach.
GNSSRK-4 is a four point GPS/GLONASS/Beidou2/Galileo repeater, transmitting GPS /GLONASS /Beidou2/Galileo signal. This solution offer adjustable test signal to receiver.
If need extend the system, you can add assemblies and sending antennas, so as to cover satellite signal indoor large area and more rooms or buildings.
Typical Application:
survey products etc.
Kits include
Used to adjust system gain,0-35 dB adjustable, you can control when needed.
with AC220/9V power adapter, supply power to system and itself.
The 1 and 2 are input/output, connect to cable assembly, N female(Can be customized).
The 3 for power control switch. system power-on when allocated to upward, opposite, system stops working.
The 4 Toggle switch can adjust the gain ; the position(figure) that toggle switch stop represents the total value of gain reduction (on the basis of maximum gain 35dB).

GPS repeater RK4 fault location and remove:
First:Check the adapter of RGA30-SV4 whether it connects to the power supply and power-up to
RGA30-SV4. You can test the voltage between input axis and shell, if it’s about 5V,power supply was ok.RGA30-SV4 was also works ok. Or else, check the power socket to assure the contact was ok.
Second: If it’s 5V at the input of Gain Controller, 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.)
