Please explain in the area below why an STA is necessary:
ViaSat designs and manufactures satellite communications antennas. A customer desires to conduct a factory acceptance test that involves transmitting at specific frequencies for which ViaSat does not currently hold a license. Approval of this STA will allow ViaSat to perform timely acceptance testing on a transportable satellite communications system referred to as the RF Terminal (RFT). The RFT is used to enable communications between satellites and the satellite operations center. The satellite interface utilizes RF communications, and the operations center interface utilizes terrestrial wired network connections. The RFT consists of a tracking antenna, antenna feed assembly, high power amplifier, and a set of transit case mounted equipment for modulation/demodulation, satellite operations center interfaces, and system control.

Purpose of Operation
Please explain the purpose of operation:  Testing of transportable satellite communications system.

Callsign: WC9XGR
