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

Out in Front: How Much Farther?

May 1, 2014By

For some years now, we have been talking about GNSS interoperability. The concept has received so much careful attention at conferences, in R&D laboratories, in international working group forums, and behind closed high-level government and military doors, that one might understandably conclude that we have talked interoperability into existence. Not quite. Not nearly. Not by the farthest, if measuring into... read more

Moving the Game Forward: Transceivers Aboard Light Vehicles

October 1, 2013By

By John Carr and James Earl Perspectives from a senior technical specialist and a production engineer at Newmont Boddington Gold Mine. Newmont Fleet Management Services now continually monitors and plots the performance of JPS Locata alongside traditional GNSS in an effort to fine-tune the installed infrastructure. Learning to sculpt the perfect network continues as we move our JPS LocataLite transmitters... read more

An integrated GNSS+Locata system installed on drills, shovels, and bulldozers — the full complement of high-precision machines on site — at Australia’s Newmont Boddington Gold Mine has increased positioning accuracy and availability, as well as mine operational efficiencies, demonstrating an improvement in availability over GNSS-only of 75.3 to 98.7 percent. read more
