The System: Celebrating 20 Years of GPS

April 1, 2015By

April marks the 20th anniversary of GPS FOC. U.S. Air Force Space Command declared Full Operational Capability (FOC) for the GPS constellation April 27, 1995, signifying the system met all requirements with 24 operational Block II/IIA satellites in their assigned orbital slots and providing both the military Precise Positioning Service (PPS) performance standard and the civil Standard Positioning Service (SPS)... read more

Salvage in Space: Galileo Satellites Recovered

March 27, 2015By

In August 2014, they were considered lost: Two Galileo satellites ended in the wrong orbit after their launch by a Soyuz from Kourou, French Guiana. Now the two satellites have been recovered and should be able to fulfill, at least partially, their mission, according to the ESA (the European Space Agency) — a situation made possible by the extended Galileo team, ESA... read more

Galileo 6 Signals Acquired

March 18, 2015By

News courtesy of CANSPACE Listserv. On March 17, some stations participating in the International GNSS Service Multi-GNSS Experiment acquired E1 and E5a signals from Galileo 6 (FOC-FM2, GSAT0202). The satellite is using pseudorandom noise code E14. The orbit of Galileo 6 was recently adjusted to make it more circular with a higher perigee after it was launched into an incorrect orbit... read more
