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 A is existing and is already included in the license. GMRC proposes to add Repeaters B, C, D, E, and F. 1

The following table provides information about the directionality and orientation of each of the repeaters shown above. Repeater GLI-Metro-G Variant Width of Beam in Orientation in Orientation in Degrees at the Half Horizontal Vertical Plane Power Point Plane (degrees from (degrees from horizontal) True North) A L1+L2 110 +/-5 at -3dB from 180 30-45 below Peak horizontal (Free Space) B L1 75 +/-5 at -3dB from 180 30-45 below Peak horizontal (Free Space) C L1 75 +/-5 at -3dB from 180 30-45 below Peak horizontal (Free Space) D L1 75 +/-5 at -3dB from 0 30-45 below Peak horizontal (Free Space) E L1 75 +/-5 at -3dB from 0 30-45 below Peak horizontal (Free Space) F L1 75 +/-5 at -3dB from 180 30-45 below Peak horizontal (Free Space) 2
