Launch Prep on Track for Galileo’s Next FOC Satellites

March 12, 2015By
Soyuz’ Block I third stage is mated to the launcher at the Spaceport’s MIK integration building.

Preparations for Arianespace’s next Soyuz flight, which will lift into orbit two more Galileo satellites, are in full swing at multiple locations across the spaceport in French Guiana. Work includes a key integration step for the medium-lift launcher, plus the start-up of fueling for its Galileo satellite passengers. Soyuz’ Block I third stage was mated to the vehicle’s core during activity today in the... read more

Orbit of Second Wayward Galileo Satellite Adjusted

March 11, 2015By

Editor’s Note: See the report from the European Space Agency here. An official with the European Space Agency has confirmed that the sequence of maneuvers to adjust the orbit of the second of two Galileo satellites launched into a wrong orbit in August 2014  has been completed. The orbit of the first satellite, known variously as GSAT0201, Galileo FOC-FM1 or Galileo... read more

BeiDou Numbering Presents Leap-Second Issue

March 3, 2015By
Leap-Second-O

During preparation of playback scenarios for the upcoming leap-second event taking place in June, engineers at Racelogic identified a potential pitfall for GNSS engineers. The difficulty arises from the fact that BeiDou uses a different “day number” for the date to apply the leap second, compared with GPS and Galileo. GPS and Galileo use 1-7 as week day numbers, and... read more
