INTELSAT 25 satellite: beam coverage maps

The ProtoStar I satellite was built by Space Systems/Loral (SS/L) as the ChinaSat-8 satellite. On January 5, 2007 SS/L announced the satellite, which had been in storage, would be modified to meet ProtoStar's requirements.

Launched July 7, 2008.  ProtoStar I was placed into its geostationary orbital location of 98.5 degrees East Longitude. Official launch ID: 08034A

The satellite has had multiple names since launch: Protostar 1, Chinasat 8, Zhongxing 8 and Intelsat 25.
