Product Description

Functional Description

GBRK-4 is a repeater operates by receiving GPS/Beidou 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.

GBRK-4 is a four point GPS & Beidou repeater, four transmitting antenna transmit GPS L1 & Beidou2 B1
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.

Standard Configurations:

◇ Step Adjustable Amplifier:RGA30-SV4,1 ea;
◇ Receiving Antenna: TIMING4200,1 ea;
◇ Cable Assembly:RG8,30M, 1ea;
◇ Cable Assembly:KSR240,20M,4 ea;
◇ Sending Antenna:GRA10,4 ea.
◇ Ligtingprotector:1 ea;

Typical Application

☆ For GPS/Beidou products testing
     For testing the cell-phone with GPS & Beidou , PND, car navigators, tracker, survey products, etc.

☆ For the purpose of GPS/Beidou signal covering

     Car parks, lab, aviation manufacturing hangar, trade shows, Emergency, safety vehicles, public
     transportation etc.

BGRK-4 System

☆ System signal :
                    GPS L1(1575MHz);
                    Beidou2 B1(1561MHz);
☆ This is four solution, covers 5-20 meters at radius (by increasing the amplifier according to methods and under field conditions, building height and other certain conditions reach a radius of 20 meters).
     Note: Four point means many antenna be used to transmit GPS、Beidou signal.

System Schematic

1. GPS Antenna(TIMING 4200) be installed on roof of the building;
2. Cable assembly RG8 fixed along the out wall, one terminator connects TIMING4200,the another to protector at the appropriate place. In some special environment, select PE or PVC material plastic pipe to protect the cable assembly is quite sensible;
3. Protector and Step Adjustable Amplifier are fixed on ceiling or on the table;
4. Cable assembly KSR240 is fixed along the ceiling of the operating place;
5. Antenna GRA10 be fixed on the ceiling .
     According to the actual environment, you can adjust positions of some parts, which can make you the
     adjust, change and overhaul more easily.

FAQ

Typical faults and solutions

GPS repeater BGRK‐4 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 TIMING4200 .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 TIMING4200 can be
suspected.(In fact, this case hasn’t appear in our engineering projects.
