Experimental Program

Experimental description As an antenna manufacturer, ViaSat, Inc. designs and produces a variety of antennas supporting a wide variety of frequencies. The request for Special Temporary Authority (“STA”) is in support of a customer requirement to test the S band antenna system over the air. The test requires communication with two operational satellites Worldview-1 and Worldview-4 which are in a low earth orbit (“LEO”). The antenna system being tested is 7.3 m (24 ft) in diameter, but is located next to nearby buildings and other existing antennas of similar size and larger and does not present a hazard to aircraft. See terrain profile drawing. The testing is expected to take place between normal business hours (8 AM to 8 PM EDT). The point of contact for ceasing transmissions in case of interference is Eric Rhoden (1-706-799-2786). WorldView-1 Parameters: Perigee: 497 km Apogee: 504 km Inclination: 94.49° Period: 94.49 minutes WorldView-4 Parameters: Perigee: 609.95 km Apogee: 613.28 km Inclination: 97.98° Period: 96.93 minutes
