AMC-8 Satellite Experiencing Power Problems
Mar 30, 2006 - In a memo sent to its clients, SES Americom has notified the users of the AMC-8 satellite that failures of three power circuits have pressed SES Americom to begin work to relocate the services currently distributed via the satellite. AMC-8 carries a large number of radio broadcast programs, including heavy usage by ABC, Clear Channel, Jones and Westwood One.
According to the memo, three separate power circuit failures on the south solar array have reduced the satellite's power by about 25 percent. The satellite has compensated for the power loss, which so far has not resulted in any signal reception problems. While the satellite's power is reduced, the output power of the transponders is still above the minimum acceptable power margin.
AMC-8 began service in March 2001. It has an expected lifespan of 15 years. The Lockheed Martin A2100 spacecraft is located at 139 degrees west longitude. The satellite is equipped with four solar panels total (two south, two north). SES Americom is working with Lockheed Martin to investigate the problem.
If a fourth power circuit fails, SES Americom will shut down an unused transponder to conserve power. If a fifth circuit fails, some of the satellite users will need to turn some of their transponders off.
There is a backup satellite in orbit, but it is not exclusive to AMC-8. Because of this, SES Americom is working with the four main users to arrange relocation plans. It is expected that the four major radio providers will work together to move to the same replacement satellite for the ease of its customers instead of relocating to different locations.
If this is true, most syndicated program would be affected. Rush, Hannity, several of the music based formats from ABC, Jones...etc...
