ViaSat, Inc. asked the FCC for authority to launch and operate Ka-band satellites VIASAT-KA and VIASAT-KA1. The satellites would be located at 115.2 degrees west longitude and 77.3 degrees WL, respectively. Both would operate in the 18.3-18.8 GHz, 19.7-20.2 GHz, 28.35-28.6 GHz and 29.35-30.0 GHz bands. ViaSat requested a waiver of FCC rules requiring disclosure of the relationship between the satellite’s receive antenna gain pattern and gain-to-temperature ratio and saturation flux density. ViaSat also asked for a waiver of rules requiring the disclosure of the gain of each transponder and rules requiring predicted space station antenna gain contours for each transmit and receive antenna beam. This information is from FCC Report SAT-00443.
