The satellite was launched on July 31 from the Xichang Satellite Launch Center in China's Sichuan province. The inclination of the mean orbit is 55.06 degrees with eccentricity of 0.0036 � an essentially circular orbit. The mean east longitude of the sub-satellite ground point is 115 degrees, 47 minutes. Here is a plot of the repeating ground track: http://www.gpsworld.com/files/gpsworld/nodes/2010/10315/beidou_igso1_ground_track.jpg At its northern most sub-satellite latitudes, the satellite should be visible from Europe and parts of North America permitting signal analysis from facilities in those regions. This is one of the first, if not the first, satellite to use such a highly inclined circular geosynchronous orbit. The Solar Dynamics Observatory satellite is in a circular IGSO with an inclination of 28 degrees. The IGSO satellites of Sirius Satellite Radio use highly elliptical so-called "tundra orbits."
