Garuda 1was an Indonesiancommunications satellitewhich is operated byACeS.It was constructed byLockheed Martinand is based on theA2100AXXsatellite bus.It has two very large antennas, each measuring 12 meter in diameter. Launch occurred on 12 February 2000, at 09:10:54 GMT. The launch was contracted byILS,and used aProton-K/DM3carrier rocket flying fromSite 81/23at theBaikonur Cosmodrome.
History
[edit]At the time of its launch, it was the heaviest commercial payload to be launched by aProton.During its launch, the Block DM3 upper stage made three burns instead of the usual two. This was the first time that the Block DM had used a three-burn ascent profile.
Following its launch and on-orbit testing, it was placed ingeostationary orbitat 123° East, from where it provides communications services toAsia.It is equipped with 88 transponders, allowing it to cover the entire continent with 140spot beams.The satellite is controlled byACeSSatellite Control Facility situated inBatamisland,Indonesia.
The Garuda 1 was originally to be supplemented by a second satellite (Garuda 2), but the plan never materialized.
An anomaly with some of the antennae was discovered in September 2000, and significantly reduced the satellite's communications capacity. A few years later more anomalies were found, further reducing its capacity by more than 50%. Several curative actions have been taken byACeSengineers to salvage the satellite and it is expected to survive another 5–7 years.[citation needed]
In mid-2015, the satellite experienced another malfunction, making it in unusable state. After the malfunction, the satellite was finally retired and was moved into a graveyard orbit.
