I. GIR-2005 Overview
Globalstar using the LEO-satellites provides high quality communication services. But,
the services are not available in the NLOS (Non Line-Of-Sight) environments such as indoors,
tunnel and etc. GIR-2005 (Globalstar Indoor Repeater) can assist to provide the seamless
Globalstar Services in the NLOS environments.
1. GIR-2005 Service Network
At the indoor environment where the LOS environment is not constructed between the
satellite and the terminal, we can provide the Globalstar Service to the terminal that is located
on the indoor by connecting the outdoor unit and external antenna for the link with the
satellite, indoor unit and indoor Tx/Rx patch antennas for the link with the terminal.
2. GIR-2005 Overview
Place the GIR-2005 ODU (Outdoor Unit) and the external antenna on the building roof,
and put IDU (Indoor Unit) and its patch antennas inside the building. These two units receive,
amplify, and retransmit each downlink signal of the satellite and uplink signal of the terminal
to expanded signal arrival area. Thus the service is possible in the interior.
Unlike a general ground mobile communication repeater, signal level of GIR-2005
received from the satellite is feeble differently and the fluctuation over time varies hourly.
Therefore a high gain amplifier is necessary, but the possibility of oscillation may increase
due to the high gain amplifier. To prevent the oscillation, the isolation between ODU and IDU
antenna must be over 80dB.
3. GIR-2005 Configuration
GIR-2005 Repeater is composed with one Indoor Unit, one Outdoor Unit and Indoor
Antenna Set(Tx/Rx Patch antennas).

II. Preparation to install the GIR-2005
1. Safety
1. 1. Before you begin, refer to the local Safety standard for the power source,
grounding, and other safety information.

III. GIR-2005 Installation
First turn off the power, and install IDU inside of building, and ODU outside of building
where has clear visibility with no obstacle facing. “On top of the roof” is recommended place
to put. After installing IDU and ODU, connect IDU and ODU with appropriate cable. Then
turn on the power. Using control panel of IDU, set up the parameters of IDU & ODU to work
properly. While doing this procedure, must take a note below for considerations of installation.
 To avoid oscillation, the indoor and outdoor antenna must be get 80dB of
minimum Isolation.
 For the installation place of the repeater in indoors, secure the visibility range
as possible, and separate from the outdoor antenna as far as possible.
Follow the instruction below to install IDU & ODU to the appropriate place.
1. IDU (Indoor Unit) Installation
IDU can be placed on the supporting structure like a desk or installed on the interior
wall. If choose to install on the wall, fallow instruction below. Then connect cables
from each of TX, RX patch antennas to IDU as described in this manual. Please note
that all the procedure must take while power is off.
1.1 Fixing
At first, using the M12 Anchor bolts, install GIR-2005 Chassis bracket into the wall
Bracket that is fixed to the wall in Figure 3-1. And then, using M4 bolt, assemble GIR-
2005 with Chassis bracket and wall-bracket.

1.2 Grounding
After GIR-2005 Indoor Unit is fixed to the wall, using 14 Square Cable put the ground
post of GIR-2005 chassis to the earth where has good conductivity. Refer to the figure
below.

1.3 Connecting Internal antenna with cables
Place GIR – 2005 indoor antenna close to the ceiling and far from the window of inside
the building. Antenna direction is recommended to face to wall side not to window side
to minimize coupling between Indoor and outdoor antenna. Install the each of indoor
patch antennas at the right and left side of the Indoor Unit. Do not exceed 3 meter for the
distance between IDU and indoor patch antenna each. Connect TX/RX cables from
antenna to IDU.
2. ODU (Outdoor Unit) Installation
Place ODU outside of building with no visible obstacle in front of ODU. Follow the
instruction below to install ODU on the proper place, install external antenna, and
connect cables between antenna and ODU as well. Refer to the figure 3-3 below.

2.1 Fixing
Outdoor Unit either can be installed to the wall or mast Pipe. If you select a wall to fix,
do same as what you did with Indoor Unit. If you select a mast pipe to fix, first find
the solid structure and fix the 20~30mm diameter pipe to it, and assemble ODU to the
pipe using a wall and pipe bracket.
Fig 3-4 Outdoor Unit Fixing to the wall
2.2 Grounding
After GIR-2005 Outdoor Unit is fixed, should ground it using 14 Square Cable
connected to the grounding post of GIR-2005 chassis and earth where has good
connectivity.
2.3 Connecting Internal antenna with cables
Connect cables with TX/RX making to relevant place of ODU using specified cables
like figure from each of TX RX patch antennas to IDU like figure 3-5. Please note that all
the procedure must take while power is off.
