Exhibit #3 Directional Location of Re-Radiation Equipment The GLI-Metro-G repeater (more specifically the passive transmitting antenna attached to the repeater) is directional. Below is the system diagram of the crash test facility with the proposed GPS repeater locations. Repeater 1 is existing and is already included in the license. GMRC proposes to add Repeaters 2, 3, 4, 5, 6, 7, and 8. 1

The following table provides information about the directionality and orientation of each of the repeaters shown above. Repeater Width of Beam in Orientation in Orientation in Degrees at the Half Horizontal Vertical Plane Power Point Plane (degrees from (degrees from horizontal) North) 1 75 +/-5 at -3dB from 180 0-45 below Peak horizontal (Free Space) 2 75 +/-5 at -3dB from 180 0-45 below Peak horizontal (Free Space) 3 75 +/-5 at -3dB from 180 0-45 below Peak horizontal (Free Space) 4 75 +/-5 at -3dB from 180 0-45 below Peak horizontal (Free Space) 5 75 +/-5 at -3dB from 0 0-45 below Peak horizontal (Free Space) 6 75 +/-5 at -3dB from 0 0-45 below Peak horizontal (Free Space) 7 75 +/-5 at -3dB from 0 0-45 below Peak horizontal (Free Space) 8 75 +/-5 at -3dB from 180 0-45 below Peak horizontal (Free Space) 2
