What is ROGER™ GNSS Repeater?
The ROGER™ GNSS repeater operates by receiving GNSS satellite signals with an externally mounted
antenna and relaying or repeating those signals to the area requiring coverage.
To use GNSS satellite devices inside your building you will need a repeater system to relay the signals from
the outside to inside where there is no coverage. A repeater is a device that receives GNSS signals and re-
transmits them to the area required. This is achieved by connecting the repeater to an externally mounted
antenna via a coaxial cable to its location inside the building.
The GNSS satellite navigation device can now receive the GNSS signal using the relayed signal from the
ROGER™ GNSS repeater. When the satellite navigation device is moved from the repeater covered area to
outdoors, the receiver seamlessly tracks the location, without resorting to the time-consuming acquisition
of GNSS almanac data (its history).
Notes:
1. The ROGER™ GNSS repeater can be used for indoor navigation, however it should be noted that the
receiver gives the position of the outdoor antenna.
2. The ROGER™ GNSS repeater fulfils the EN 302 645 V1.1.1 (2010-03) specification requirements,
meaning that it can be used throughout the EEA and in fact, world-wide.
3. The use (taking into use) of GNSS repeaters (such as ROGER™ GNSS Repeaters) in many markets
requires a radio licence to allow its use. The GNSS repeaters are intended for use by professional
business users, companies and institutes. Check the licensing regulations, conditions and how to
apply for a license from your local regulator authority before operation.
4. If the user of the GNSS repeater is an individual person, a radio license must be applied for before
the GNSS repeater is taken into use, usually available from the local regulation authority.

Description of GNSS Repeater controls and connectors (applies to repeater GNSS-L1G1GA):
1. Gain control knob: The gain control knob is used to control the output signal level (gain variation
when turning the knob is 0-40dB) of the GNSS repeater output power.
2. DC power connector: The repeater power is supplied through the DC input connector. The
connection is reverse polarity protected with 12V DC.
3. Receiving antenna connector: The outdoor antenna is connected to the SMA input on the repeater
front panel with the coaxial cable.
a. ROGER™-GPS has product packages that include the cable.
b. Alternatively, a 50Ω custom cable can be used. On the repeater
panel, the connector is SMA female so the cable end
should terminate with a SMA male. The other end of
the cable should terminate in a TNC male, the antenna
itself being TNC female.
c. The repeater feeds +5VDC 100mA for
active outdoor antenna.
4. Status LED indicator
5. Integrated transmitter (TX) antenna inside the case.
ROGER™-GPS Repeater GNSS-L1G1GA
A single ROGER™ GNSS Repeater is enough to provide a GNSS indoor coverage area up to 1600 square
meters (m2). The modern receivers can detect the signal at very low power levels, so the distance can
reach up to 50-60 meters from the repeater’s center, depending on surrounding structures. Several
ROGER™ GNSS Repeaters can be installed in the same building. Alternatively, the signal coverage
provided by a single package can be extended with ROGER™ GNSS additional products such as line
amplifiers and signal splitters.

ROGER™ GNSS repeater installation for GNSS-L1G1GA
Prior to commencing work on the installation, make a survey of the locations of the individual units,
ensuring that:
1. The antenna has good line of sight to the sky and is not shrouded or shadowed by buildings, trees
etc. and will not cause an obstruction to doors, windows, or ventilators and is located away from
any machinery HVAC, fans etc. Always connect the antenna cable before powering the repeater.
2. The antenna feeder cable can easily be routed indoors and can be properly secured to walls and or
ceilings.
3. The building protection and integrity is not compromised; i.e. breaching of fire stopped
compartments.
4. If possible, install the power supply and antenna feeder cables away from existing cables, pipes etc.
5. There is a nearby power supply to connect the repeater to.
6. The final location of the repeater allows for maximum coverage of the area.
Install the GNSS repeater transmitter by fixing it to the ceiling, wall or other suitable mounting point. The
repeater has an integrated transmitter TX antenna, located internally, on the same side as the status LED.
The transmitter antenna generally radiates in the same direction as the LED. Ideally the transmitter should
be located so that any desired GNSS receiving location, for example an antenna on top of a van in a garage
has a direct line-of-sight to the repeater antenna. After installation, prior to switching on, ensure all
connections are tight.
Switch the power on and the indicator LED will flash
green for between two and three seconds during the
start-up phase.
Turn the control knob in order to set the gain. A higher
gain increases the coverage of the GNSS signal.
Watch for the LED flashing to red and green, this means the
maximum power has been reached.
Turning the knob too far clockwise will result in the LED
turning red, indicating the gain setting is too high.
Constant green light indicates proper gain setting. Turning
the knob too far counterclockwise will result in the green
LED to blink indicating too low gain setting.

The indications of the status LEDs are:
CONSTANT GREEN:
The transmitter is working correctly, no further adjustment is required.
CONSTANT RED/GREEN:
The transmitter is working at its maximum output and the gain should be reduced slightly until a
constant green is achieved.
CONSTANT RED:
The Transmitter has detected an error or interfering signal. One reason may be that the external
antenna is picking up the signal from the transmitter and a feedback oscillation is occurring; it is
strongly advised not to locate the external antenna and repeater too close together.
It may be that the power is set too high; decrease the gain on the repeater slightly.
Another common reason is that there is an interference source close to the receiving antenna.
Locating the antenna, repeater and associated cables as far away from existing wiring, machinery and
pipework will normally avoid this situation.
Troubleshooting guide:
Problem: No LED indication
Solution: Check power supply and connection.
Problem: Red light is on.
Solution: The gain setting is too high. Turn the control knob counterclockwise to decrease the gain
until the green LED is lit.
Problem: Green light flashing around 5 times per second, red light is off.
Solution: Transmitted signal level is too low. Turn the control knob clockwise to increase the gain. In
normal operation, only the green LED is continually on. In all other cases please check the
antenna connections at both ends before making any gain adjustments.

Extending the ROGER™ repeater’s distance
from the outdoor antenna.
ROGER™ GNSS Amplifier (GNSS-A)
ROGER™ GNSS Line Amplifier is used to allow
longer cable runs and/or signal splitting to several
GNSS Repeaters.
It has a gain of +16dB and it includes a filter to
remove unwanted signals that may have entered
the cable at some point. Amplifier is powered
through the output signal cable by the ROGER™
GNSS Repeater and it passes on DC power for the
GNSS receiving antenna or another GNSS line
amplifier.
Extending the number of repeaters by
adding a Splitter 1 to 5.
ROGER™ GNSS Splitter 1 to 5 (GNSS-S)
With the ROGER™ GNSS Signal Splitter, the signal
from one external antenna can be redistributed
to up to five repeater units.
It is advisable to use a separate amplifier with the
signal splitter to ensure adequate transmission
power to all the five repeaters. If the signal is to
be transmitted to fewer than five repeaters, the
unused ports must be terminated with a 50ohm
termination. The splitter is powered through the
output signal cable by the ROGER™ GNSS
Repeater and it passes on DC power for the GNSS
receiving antenna or GNSS line amplifier.

Extending the number of repeaters by
adding an Amplifier/Splitter
ROGER™ GNSS Amplifier& Splitter(GNSS-AS)
ROGER™ GNSS Amplifier & Splitter is a combined
signal splitter and line amplifier with an output of
+12dB (1 port) and +4 dB (2 ports) that can
transmit to up to three separate repeater units.
In order to get the amplification, the ports must
be connected as shown below. The unused ports
must be terminated with a 50ohm termination if
less than 3 repeaters are connected to GNSS-AS.
Extending the number of repeaters by
adding a Splitter 1 to 2
ROGER™ GNSS Splitter 1 to 2 (GNSS-S2)
With the ROGER™ GNSS Signal Splitter 1 to 2, the
signal from one external antenna can be
redistributed to up to two repeater units.
It is advisable to use a separate amplifier with the
signal splitter to ensure adequate transmission
power to all the two repeaters. If the signal is to
be transmitted to only one repeater, the unused
port must be terminated with a 50ohm
termination. Splitter is powered through the
output signal cable by the ROGER™ GNSS
Repeater and it passes on DC power for the GNSS
receiving antenna or GNSS line amplifier.
