WAAS Intelsat GEO Currently Experiencing Technical Difficulties (Regarding WAAS 48 PRN 135)

April 12, 2010 - Intelsat has notified the Federal Aviation Administration of a technical issue currently being experienced with the telemetry tracking and control system (TT&C) of their Galaxy XV satellite. The Intelsat Galaxy XV is one of the geostationary satellites (GEO) that broadcasts the WAAS signal in space.

For WAAS users, there is no immediate impact to service; but over the next few weeks, the Intelsat GEO will drift out of its current orbit position, ultimately requiring the GEO broadcast to be discontinued.
