The first spacecraft in the U.S. Air Force’s Advanced Extremely High Frequency (AEHF) military communications satellite network, launched Aug. 14, will spend the next three months circularizing its orbit. When circularization is complete, the spacecraft will fly about 22,300 mi. over the equator at 90 deg. W. Long. for a period of satellite checkout and calibration. It will then be moved to an operational orbit, and should be ready to be put into service in early 2011.
An ongoing trial of space-based ship detection by the South African Maritime Safety Authority demonstrated the ability to improve security during the recent World Cup tournament, according to service provider ExactEarth. The Cambridge, Ontario-based company is demonstrating the provision of space-based automatic identification system (AIS) data using a microsatellite in low Earth orbit. The demonstration uses the Canadian Nanosatellite Tracking of Ships (NTS) spacecraft launched in 2008.
