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, 2, 3 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 the hours 0f 1300 to 1500 local time as per the pre-coordination with the local broadcasters. The point of contact for ceasing transmissions in case of interference is Eric Rhoden (1-706-799-2786).
