Second Compass Satellite

摘要

On April 15, China launched a second Beidou/Compass global navigation satellite, destined for geostationary orbit along the equator at an altitude of about 22,300 miles.rnThe Compass-G2 satellite has been characterized as of a "second generation," representing a transition from a regional satellite navigation system, for which four test satellites were previously launched, to a global concept. China launched the first second-generation Compass satellite into medium-Earth orbit in April 2007. Compass G2 is the first geostationary satellite of the group.
