4.5 INSTALLATION CONSIDERATIONS
Before you start to install the terminal, read the following sections carefully:
 Terminal location and mounting considerations
 Structural modifications, painting and sealing
 Wiring Diagram
 Grounding
 Alignment and installation limitations
4.5.1 Terminal Mass and CG
The mass of the AVIATOR UAV 200 is approximately 1.45 kg with a Centre of Gravity (CG) as shown in the
mechanical outline drawing, 677-A0219_OD [2]. The mass and CG will need to be used in the CG calculation
of the aircraft after installation.
4.5.2 Terminal Cooling Considerations
Install the terminal so that the flanges can dissipate heat into the mounting/airframe structure, or the
surrounding air. The aircraft structure can be used to dissipate the heat into the air stream during flight.
During standby mode (receive only) the terminal dissipates approximately 8 W of power. This increases up
to 25 W while transmitting.
The terminal is capable of operating over the temperature range of -40 °C to +55 °C [-40 °F to +131 °F].
Operating the terminal outside of the operating temperature range may be degrade its performance as part
of self-protection mechanisms.
When operating the terminal on the ground where no or minimal airflow is available, additional cooling may
be required for long test runs.
4.5.3 Terminal Location
The terminal must be installed under a radome/dust cover or RF transparent fuselage section with the
greatest possible clear view of the sky.
Ensure that UAV 200 is installed such that aircraft components don’t cause RF beam blockage. The installer
must ensure the equipment is mounted so as to ensure minimal RF blockage.
