Autonomous relative navigation

April 1, 2016By

Future UAVs will require relative navigation capability to fulfill a broad range of assisted manned and unmanned missions. A new approach, demonstrated in application to aerial refueling, provides access to accurate relative time-space positioning information (R-TSPI) between platforms. By Shahram Moafipoor, Jeffrey A. Fayman, Lydia Bock and David Honcik The advent of unmanned aerial vehicles (UAVs) highlights the importance of precise... read more

GPS recruits: Uncle Sam wants your ideas!

January 27, 2016By

The GPS modernization funding picture cannot be called bright, yet neither can it be characterized as dim. While big money for big projects appears hard to come by, the U.S. government and military offer many smaller allocations to help fill the chinks in GPS armor. Such initiatives concern jamming, PNT solutions in GPS-denied environments and other conundrums. A run of... read more

NextNav supports metropolitan beacon system for mobile

January 19, 2016By

The final specification for 3GPP Release 13 will include messaging support for Terrestrial Beacon System (TBS) location technologies, including the Metropolitan Beacon System (MBS). NextNav is deploying the MBS positioning technology across the U.S. to allow mobile phones and other devices to reliably determine their location in indoor and urban environments where GPS signals can’t be received. NextNav has adopted... read more

Will Military Take the Autonomous Vehicle Lead?

ARLINGTON, Va. — Despite shrinking defense budgets, existing and emerging worldwide threats will make robotic and autonomous systems’ development important for decades, said officials at the Unmanned Systems Defense 2015 conference held here Oct. 27-29. Because America has been at war for more than 14 years, unmanned technology has been developing at a rapid rate, perhaps even faster than emerging autonomous... read more

Rockwell wins DARPA Contract for GPS Backup Tech

October 13, 2015By

Rockwell Collins has been selected by the Defense Advanced Research Projects Agency (DARPA) to develop technologies that could serve as a backup to GPS. The research, being conducted as part of DARPA’s Spatial, Temporal and Orientation Information in Contested Environments (STOIC) program, aims to reduce warfighter dependence on GPS for modern military operations. Under the terms of the agreement, Rockwell... read more

The current WINS form factor (left) sits beside a prototype for the future incarnation.

A new device is being developed to enable foot soldiers to find their exact location in GPS-denied situations. If satellite signals are blocked by heavy jungle canopy, or because of enemy interference, soldiers — and Headquarters — will still know where they are with the Warfighter Integrated Navigation System (WINS). read more

Exelis, UrsaNav to Demo eLoran with Homeland Security, Coast Guard

May 22, 2015By

Exelis, UrsaNav, the Department of Homeland Security’s Science and Technology Directorate (DHS S&T), and the U.S. Coast Guard have entered into a cooperative research and development agreement (CRADA) for testing and demonstration at former Loran-C sites. The team will evaluate eLoran as a potential complementary system to GPS. The capabilities and potential utilization methods of eLoran will be explored in depth to... read more

Sensors in Motion Launches MEMS-Based Inertial Nav System

November 24, 2014By

Sensors in Motion (SIM) has introduced  a MEMS (micro-electro-mechanical) navigation-grade inertial system (INS) that it says could transform the $8 billion/year inertial market with new products by offering price and performance specifications better than those currently available. The first INS devices have been delivered to the Army CERDEC Night Vision Electronic Sensors Directorate (NVESD). SIM, a spinout from NASA’s Jet Propulsion Laboratory and California Institute... read more
