FCC Form 442 Exhibit 1 Request for Experimental Authorization Iridium Satellite LLC (“Iridium”) herein requests experimental authority to demonstrate and test earth station facilities in connection with Iridium’s non-geostationary satellite orbit space station constellation (Call Sign S2110) in the manner described below. Iridium seeks authority for a period of twenty-four (24) months. The thirty (30) earth station terminals are experimental proto-type terminals that will be divided into ten (10) units, fixed to the building, at each location. They are low-gain omni-directional antennas with a hemispheric coverage of +3 dBi. Necessary Bandwidth Description The necessary bandwidth is determined by the frequency channelization that Iridium uses and is filed with other Iridium licenses. The frequency of a center of an Iridium channel can be calculated by this equation. There are 270 channels numbered 1 to 270 for transmit and 7 more that are receive only. 𝑐ℎ𝑎𝑛𝑓𝑟𝑒𝑞𝑢𝑒𝑛𝑐𝑦 = 1616 × 106 + ((41.6666 × 103 ) × ((𝑐ℎ𝑎𝑛𝑛𝑢𝑚𝑏𝑒𝑟 − 1) + 0.5)) 𝑀𝐻𝑧 Ground station locations: (1) SNOC (39° 05’ 19” N 077° 30’ 43” W) 44330 Woodridge Parkway Leesburg, Loudoun, VA Elevation MSL(m): 91.75 Elevation AGL(m): 9.75 (2) HQ (38° 55' 26.2" N 077° 13' 22.1" W) 1750 Tysons Blvd McLean, Fairfax, VA Elevation MSL(m): 168.44 Elevation AGL(m): 93.44 (3) TSC (33° 16’ 44.5” N 111° 53’ 26.9” W) 1800 South Price Road Chandler, Maricopa, AZ Elevation MSL(m): 366.73 Elevation AGL(m): 9.73
