This test must be conducted outside, as the use of a GPS repeater inside a hangar
may result in a failed test.
1)
Ensure a valid GPS position fix is obtained by monitoring the GPS status.
The following status indications are valid fixes for this test.
• 3D Fix
• 3D Differential
2) Select 121.150 MHz on the COM transceiver.
3)
Transmit for a period of 30 seconds while monitoring the GPS status.
4)
During the transmit period, verify that the GPS status does not lose a valid
GPS position fix.
5)
Repeat steps 2 through 4 for the following frequencies:
• 121.175 MHz
• 121.200 MHz
• 131.250 MHz
• 131.275 MHz
• 131.300 MHz
6)
Repeat steps 2 through 5 for all other installed COM transceivers (if
applicable).
7)
If an installed COM supports 8.33 MHz channel spacing, increase the
transmit period to 35 seconds and repeat steps 3 through 5 for the
following frequencies:
• 121.185 MHz
• 121.190 MHz
• 130.285 MHz
• 131.290 MHz
8)
Repeat step 7 for all other installed COM transceivers supporting 8.33 MHz
channel spacing (if applicable).
NOTE: The signal strength bars at the bottom of the GPS Configuration page
are a real-time representation of GPS signal strength, which may be useful for
troubleshooting a failed COM interference test.
