The U.S. Air Force's Interface Control Working Group (ICWG) has recently released publicly-available draft versions of updated GPS Interface Control Documents. The documents specifically address the use of forthcoming new civilian signals.
Lockheed Martin has joined Northrop Grumman Corp.'s team competing for the U.S. Air Force's (USAF) GPS Next Generation Control Segment (OCX) Phase B contract.
Raytheon Co. has won a $61 million U.S. Air Force contract from the GPS Wing to complete the development and certification of next-generation GPS receivers.
When there's somthin' weird, in your neighborhood, you call Dan Akroyd and Bill Murray. But when there's a problem with GPS signal reception in your neighborhood, whom you call might not be so obvious, and depends on whether you wear civvies or fatigues.
Don Jewell, contributing editor for GPS World's military and government section, interviewed Col. Mark Crews (pictured above), chief engineer at the GPS Wing, U.S. Space Missile Command, regarding GPS anomalies that occurred in October 2007 that resulted in a great deal of concern in the international user and monitoring community.
The Navigation Nugget, first GPS receiver in the world to incorporate a chip-scale atomic clock, will transform designs for the future, enabling warfighters and warfighting platforms to navigate in waters and terrains that can be unattainable with current standalone GPS receivers.
From the safety of workers to the protection of assets and the transportation of hazardous materials, GPS tracking has become an increasingly important safeguard against security threats. But users must be aware of the technology's vulnerabilities and of the tools needed to ensure protection.
Modeling and simulation, two separate but related activities conducted prior to flight tests of high-performance military navigation systems, can reduce costs, shorten timelines, and remove some uncontrollable variables from the process, to deliver more accurate, verifiable results.
GPS technology helped the U.S. Air Force take out al-Qaeda leader Abu Musab Al-Zarqawi in a June 14 airstrike. "GPS provides the precision timing and navigation absolutely instrumental in both protecting our troops on the ground and taking out the bad guys," said an Air Force brigadier general.
