Boeing, Northrop Grumman Enter GPS III Bid

July 8, 2014By

Northrop Grumman and Boeing have responded to a U.S. Air Force call for contractors interested in building a follow-on set of GPS III satellites, according to a report in Space News. Lockheed Martin is under contract to deliver the first eight GPS III satellites, but the award for up to 22 further IIIs remains open. Difficulties with the payload for... read more

Power Loss Created Trouble Aboard Galileo Satellite

In an update to our July 2 story (recapped below), correspondent Peter de Selding wrote in Space News on July 3 that the trouble aboard the fourth in-orbit (IOV) Galileo satellite arose from a sudden, unexpected loss of power. The power outage flashed on May 27, shutting down the satellite’s E1 signal. The signal “re-established itself almost immediately. But as... read more

A Hansel and Gretel Approach to Cooperative Vehicle Positioning
Several technologies are being developed for accurate cooperative vehicle positioning, but GNSS also has a role to play. In this month’s column, team of British researchers turn to a children’s fairy tale for inspiration in their development of a cooperative vehicle positioning approach using carrier-phase observations — another innovative application of real-time kinematic or RTK GNSS technology. read more

Europe Weighs Mandate of Galileo Chips in Mobile Phones

June 30, 2014By

The European Commission is considering a requirement for mobile phones, and perhaps other portable devices such as tablets, to be equipped with Galileo receivers that would automatically send location data as part of any emergency call to 112. E112 is a location-enhanced version of the 112 universal European emergency services number via telephone, equivalent to 911 in the United States, in which the... read more

Occupy Media Space Now EGNOS and Galileo Mission

June 29, 2014By

By Peter de Selding The message to the recent European Space Solutions conference in Prague was simple enough: EGNOS is here, so let’s use it; Galileo is almost here, so let’s promote it. Neither task is straightforward. Take the European Geostationary Navigation Overlay Service (EGNOS), the European piece of a near-global network of terminals on geostationary satellites linked to networks... read more

eDLoran: The Next-Gen Loran

Potential GNSS Back-up Improves to GPS-Level Accuracy
A new enhanced differential Loran system demonstrates 5-meter accuracy not achievable by the current DLoran system, and requires less expensive reference stations. A prototype tested in Rotterdam’s Europort area uses standard mobile telecom networks and the Internet to reduce correction data latency — a key source of error — by one to two orders of magnitude. read more
