ROGER™ GPS repeater installation instructions
Product description
ROGER™ GPS repeater is a device that is used to relay GPS signals to
places where they cannot normally be. The GPS repeater operates by
receiving GPS satellite signals with an antenna located outside f the building
and re-radiating them to the indoor or covered space. The GPS received can
then ‘see’ the satellites indoors. The use of re-radiated signals mean that the
GPS receiver is tracking the current GPS status. This means that when the
receiver is moved from the indoors to outside, the GPS receiver is instantly
tracking the location, instead of time consuming acquisition of current GPS
state.
Please note that ROGER GPS repeater can be used for indoor navigation
but you have to take into consideration that the receiver will always give the
position of the outdoor antenna instead of the real position
Operating license note
Note: GPS repeaters may require a license or they may not be used in your
country. Check licensing conditions with the local (radio)authorities before
operating the GPS repeater product. In some countries the ROGER™
package contains instructions.

Components
The ROGER™ GPS repeater system consists of the following
components:
1. GPS Repeater
2. Outside antenna for receiving GPS signals
3. Power supply
4. RF Cable
1. GPS Repeater
The GPS repeater works by receiving GPS signals from satellites with an
outdoor antenna. The signals are then transported to indoors via cable and
re-radiated by the GPS repeater. The GPS Repeater is powered from mains
by the power supply.
In addition, it is possible to use custom length cables and line ampliers to
extend the cable length and signal splitters with additional transmitters to
extend the coverage area.
Since the GPS signals are very low level, the repeater incorporates special
circuitry to limit the output level to a maximum value within the requirements to
conform with the CE requirements.

2. Outside antenna
The outside antenna is used to receive GPS satellite signals. The antenna has
a female TNC connector and requires +5VDC power through the center pin.
The power is usually supplied by the repeater, but if there is a DC block in the
cable used, the power must be supplied from an another source.
Please note that a good quality antenna and a good location are essential
for effective operation of the GPS repeater system. The standard antenna
supplied in the kit has +35dB gain and <2dB noise gure
In some cases a small patch antenna may be used. Typically this kind of
solution is used in research labs where the receive antenna can be easily
installed so that it gets the line of site from outside GPS satellites. The indoor
coverage is typically greatly reduced in this case and feedback may present a
problem (indicated by RED led indication), but is typically sufcient to bench
test handheld GPS equipment
Hint: the location of the outside antenna can be easily located by using a GPS
receiver to read the coordinates through the repeater.
3. Power supply
The GPS Repeater system is powered by a AC wall adapter supplied in the
installation kit.
4. Cable
The standard cable supplied with the repeater is of RG58 type, which can be
used for cable runs of up to 20 meters. Cable runs up to 40 meters can be
realized with RG214 and up to 90m with ECOFLEX. Longer cable runs may
require a separate line amplierto compensate the power loss in the cable.

GPS Repeater transmitter
The GPS Repeater transmitter is the main component of the system. The GPS
Repeater transmitter contains ltering, ampliers and power control circuits.
The GPS Repeater also supplies power (+5VDC, max 100mA) to the outdoor
antenna through the antenna cable.

1. Gain control knob
The gain control knob is used to control the output power of the
GPS repeater.
2. DC power connector
The repeater power is supplied through the DC input connector. The
connection is reverse polarity protected. (+12VDC 300mA in)

Installation, tools required
When installing the GPS repeater, you should have:
• a suitable tools to tighten the SMA connector
• handheld GPS receiver (*)
• Multimeter
• Suitable xing tools and accessories
(*The GPS receiver must be able to show the satellite signal levels.)
Receiving antenna installation
The receiving antenna should be placed in a place where it can ‘see’ as
much of the sky as possible. It should be also located as far as possible from
any RF interference sources, like any transmitting antennas. Before xing
the antenna, check that the cableis long enough and it can be run from the
antenna to the required indoor location.
It is also recommended that the system is rst tested by running the cable
througha convenient route to the indoor installation place and checking that
the indoor GPS coverage is suited to the use.
GPS repeater installation
Install the GPS repeater transmitter by xing it to ceiling, wall or a suitable
mount.The repeater has an integrated antenna, which is located next to the
status LED. The transmitter radiates mostly towards to the same direction as
the LED. Ideally the transmitter should be located so that any desired GPS
receiving location (like an antenna on top of a van in a garage) has a direct
line-of-sight to the repeater antenna.
Also note the AC/DC adapter´s cable lenght when planning the installation
location.

The cables should be installed so that there is no constant strong force to any
direction at the connector.
After having installed the outside antenna, cable and repeater, plug in the
AC/DC adapter cable and plug the adapter to a power outlet. The LED of the
repeater should ash a few times at startup and then turn constant red or
green
The indications of the status LED are:
• GREEN:Transmitter operating normally
• YELLOWorconstantRED/GREEN:Transmitter operating normally,
output power has been limited to maximum allowed value.
• RED: Transmitter has detected an error or interfering signal. Typical
reason is that the input antenna is located so that it can pick up
the signal from the t ransmitter and a feedback oscillation occures.
Other common reason is that there is an interference source close to
the receiving antenna.
Adjusting and testing
To adjust the repeater for optimal coverage and minimal interference, perform
the following tests and adjustments:
• Go next to the outside antenna and use the GPS receiver to record
the antena location.
• Keep the GPS receiver on and go to the GPS Repeater
• Turn the gain setting fully counter clockwise for minimum gain.
• Turn the gain setting knob clockwise until the GPS receiver shows that
it can receive satellite signals.
• By adjusting the gain knob and measuring from different places with
the GPS receiver, nd out the minimum gain setting that reliably
allows for GPS reception in the area planned. Turn the knob carefully,
it is very sensitive in some positions.
• When the LED indicator turns GREEN/RED or YELLOW, you have
reached the maximum gain setting and no more gain can be added by
turning the knob.

Troubleshooting
GPS receiver cannot receive signals next to the repeater.
• Check that +5VDC is present in the antenna end of the cable and in
the antenna connector of the repeater. Broken or short-circuited
cable?
• Check that repeater power is on and LED is on.
NoLEDindicationonGPSRepeater
• Check that +12VDC is present in the DC power cable connector
• Check that AC power is available at the power cord where the AC/DC
adapter is connected.
LED turns RED and GPS coverage is lost.
• Check that outdoor receiving antenna is in a location where it cannot
receive signals from the repeater
• Try turning down the gain setting
• Check that there are no interference signals close to the receiving
antenna. The system is very sensitive to interference at the GPS L1
frequencies (1575.42+/-20 MHz)
Small indoor coverage radius
• Check that outside antenna is correctly positioned
• Check that there are no interference sources close to the receiving
antenna
• Check gain setting
• Check the repeater positioning
• Are there obstacles that could limit signal coverage?
• Shorter cable run or a line amplier can improve signal level slightly
• Signal splitter and additional repeater units may be required to cover
a larger or obstructed areas

is typically better than –60dB. Graph indicates lower attenuation due to
measurement setup (spectrum analyzer noise oor).
