In an opinion released earlier this spring, the Florida Fourth District Court of Appeal ruled against law enforcement use of data (including GPS-based data) from a car’s "event recorder" or "black box" without a warrant. The decision was just one of many in recent months that deals with the subject, as technology advances and privacy issues are clashing on a regular basis.

SPAN Land Vehicle is designed to optimize integrated GNSS + INS performance for land vehicles during periods of extended GNSS outage, in low dynamic operating environments, or in dense urban canyons. It ensures that accurate position, velocity and attitude is maintained during such difficult operating environments.

After a couple of changes in direction and spending some $18 million to verify the technical chops of their most likely suppliers, defense officials appear ready to buy up to 22 new GPS III spacecraft. Although three firms are now well positioned to bid on the potentially lucrative contract, the Defense Department continues to leave the contracting door ajar for newcomers, just in case.

At 25 years old, Global Positioning System Satellite Vehicle Number 27 completed its time in orbit on April 18, and the 2nd Space Operations Squadron (2 SOPS) said goodbye via final command after disposal operations were complete. SVN 27 was launched in 1992, meaning it lasted more than triple its design life of 7.5 years.

Test results from the long-running Adjacent Band Compatibility (ABC) Assessment show interference from wireless signals in nearby bands could negatively impact GPS receivers kilometers away from Long-Term Evolution (LTE) ground stations and render some more closely located GPS receivers useless.
