Question 7: Purpose of Experiment

a) Per criteria in Section 8.3.28 of the NTIA Manual, the station class should be “XT.”
The GPS re-radiators will be used as “Experimental RNSS test equipment for the
purpose of testing GPS receivers” installed in aircraft while the aircraft are inside the
hangar.

Frequency 1227.6 MHz is currently being coordinated with FAA in WebFCR.

Other attachments to this application show how this system complies with the criteria
of section 8.3.28 of the NTIA Manual. Attachments to this application are:

• Facility drawing with radiating antenna location
• Power calculations
• Stop buzzer Points of Contact
• System Diagram
• FAA Coordination Correspondence

b) The specific objective we wish to accomplish is to ensure aircraft GPS navigation
systems are functioning properly without having to relocate the aircraft outside of the
hangar. Relocating an aircraft takes several people. Work on the aircraft cannot be
performed while it is being moved. Often, other aircraft must be moved to clear a path
to the hangar door. This can disrupt work on additional aircraft with associated delays
and costs.

c) This program will reduce time required to produce aircraft, increase efficiency and
contribute to ensuring the reliability of aircraft GPS navigation systems.

Very Respectfully,

Dan Hankins
Spectrum Manager - Sr
