Functional Description

GRK‐1 is a repeater operates by receiving GPS 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.
GRK‐1 is a single point GPS repeater, one transmitting antenna transmit GPS L1 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

☆ For GPS products testing
     For testing the cell‐ phone with GPS, PND, car navigators, tracker, survey products, etc.
☆ For the purpose of GPS signal covering
     Car parks, lab, aviation manufacturing hangar, trade shows, Emergency‐, safety vehicles, public
     transportation etc.

Step Adjustable Amplifier RGA30-SV

Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine Bottle Moulding Machine
PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.

Function:

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.
①②are input/output, connect to cable assembly, N female(Can be customized).
③ For power control switch. system power-on when allocated to upward, opposite, system stops working.
④Toggle 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).

Specification

Electrical Specifications, Operating Temperature -40 to 85°c

GPS antenna（Receiving antenna）: TIMING 4000

Transmiting antenna:GRA10

Cable Assembly

We apply two cable assembly,RG8,30M and KSR240,10M. Please log in , enter RG8 or KSR240,then you can see the two cable’s technical specification.

 1 RG8(KSR 400)

RG8,30M is usually used for connecting GPS antenna
TIMING4000 and lighting‐protector. You can calculate the length according to your actual environment, also 60m or 90 be selected.
Connector N Male‐N Male.
The attenuation value is 0.2 dB/m; Thus, you can assess the system, or contact with our sales to select proper configuration.

   2 KSR 240

KSR240,10M is usually used to connect RGA30‐SV and GRA10.

The attenuation value 0.4dB/M.
Connector: N Male‐SMA Male.

Typical faults and solutions

GPS repeater GRK‐1 fault location and remove:

First: Check the adapter of RGA30‐SV, whether it connects to the power supply and power‐up to
RGA30‐SV . You can test the voltage between input axis and shell, if it’s about 5V,power supply was ok,
RGA30‐SV 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 TIMING4000 .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 TIMING4000 can be
suspected.(In fact, this case hasn’t appear in our engineering projects.
