Galaxy 15

 2005-041A


Orbital Star 2 satellite 2033 kg launch, 1264 kg BOL, 885 kg dry. Size 3.3 x 1.9 x 1.5m with 12.6m span. For 133W. Under the Spelda 5E; uses 937VB5 adapter.

Galaxy 15 was owned by Panamsat until that company's purchase by Intelsat in 2006 Jul.

The L-band LMPRS-1 WAAS navigation payload is operated by Lockheed Martin for the US FAA.

In 2010, the satellite commanding systems failed and the satellite drifted off station, but the communications payload carried on transmitting, interfering with other satellites. Intelsat were unable to regain control until December, when the satellite lost earth lock, the batteries drained, and the systems rebooted.
