Rev. 5

Page 7-5

7.1.2.2 Signal Acquisition Check

NOTE

All other avionics should be turned off at the start of this test, with the GTN powered on in 
normal mode. After reinstallation, the initial acquisition of position can take up to 20 
minutes. Subsequent acquisitions will not take as long.

NOTE

For best results, this check should be performed outdoors away from large buildings or 
objects that could obstruct the GPS antenna. 

Ensure the GTN is able to acquire sufficient satellites to compute a GPS position. From the Home page, 
touch the 

System

 key and then touch the 

GPS Status

 key. Under “GPS Solution”, ensure that a 

3D Fix

 or 

3D Diff Fix

 is obtained. If the unit is unable to acquire satellites, move the aircraft away from obstructions 

which might be shading GPS reception. If the GPS solution does not improve, check the GPS antenna 
installation.

Once GPS position information is available, verify that the LAT/LON agree with a known reference 
position. 

7.1.2.3 Receiver/Transmitter Operation (GTN 635/650/750 Only)

Tune the unit to a local VHF frequency and verify the receiver output produces a clear and understandable 
audio output. Verify the transmitter functions properly by contacting another station and getting a report of 
reliable communications.
