Satellite Update

The FCC has accepted an application from XM Radio Inc. requesting authority to reposition three of its licensed satellites - XM-1, XM-2 and XM-3 at the nominal orbital location of 85 degrees West Longitude (WL). The satellites would be located side by side within an over-all station-keeping box of 0.2 degrees. XM-1 would be an in-orbit spare at 85.150 degrees WL. XM-2 would operate as an in-orbit spare at 85.217 degrees WL and XM-3 would operate at 85.083 degrees WL. To maintain this tight spacing, each satellite would have an East-West station keeping tolerance of ±0.033 degrees. XM Radio requested authority to maintain continuous operation of the communications payload on XM-3 during the move and to activate the communications payload of XM-1 and XM-2 in the event of an XM-3 or XM-4 service outage.

Sirius Satellite Radio requested special temporary authority (STA) for a period of 180 days to operate terrestrial repeaters at EIRP levels at or below 200 W and signal boosters with an EIRP of 0.0001 W at trade shows starting Nov. 7, 2007 through Feb. 18, 2008. The repeaters would operate within its licensed frequency band of 2320 to 2332.5 MHz.

This is information is from FCC Report SAT-00473.

In Report SAT-00472 the FCC International Bureau announced it granted XM Radio STA to operate one terrestrial repeater with a power level of 1462 W EIRP in Miami, FL for a period of 180 days. XM Radio also received STA to operate one terrestrial repeater with a power level of 1068W EIRP in Las Vegas, NV for a period of 180 days. Sirius Satellite Radio received STA to operate an indoor terrestrial repeater with an EIRP of 200 watts (average) and up to five indoor repeaters with EIRP up to 0.0001 W at the International Boat Builders’ Exhibition and Conference (IBEX) in Miami Beach, FL from Oct. 10-12, 2007. That STA become effective Oct. 3, 2007. DG Consents Sub, Inc received an STA for its Earth Exploration Satellite Service license S2129. Details were not listed in the FCC Report, but a check of IBFS found this description in DG’s application: “DG Consents Sub, Inc. (DigitalGlobe) seeks authority to launch and operate the W -60 spacecraft it is licensed to add to its EESS constellation, but which it proposed in July 2007 (in an application that remains pending) to modify slightly. The modified satellite will be launched on Sept. 18, 2007, so action on this request is sought on an urgent,” DigitalGlobe, is the company that provides the satellite images for Google Earth and some press releases announcing the launch of the satellite referred to it as the “Google Earth” satellite.
