AFIT, Locata Partner on GPS Technology Development

September 16, 2013By
AFIT-Locata Kick-off Meeting. This is the first picture ever released by Locata which shows their radically new switching antenna, a design that AFIT will now modify for use with GPS receivers. Pictured (L-R): Dr. Steve Hewitson & Ian Sainsbery (Locata engineers); Jason Barhorst (AFIT); David Small (Locata technology inventor), Nunzio Gambale (Locata CEO), Dr. John Raquet (Director, Advanced Navigation Technology Center, AFIT), Dr. Peter Collins (AFIT), Dr. Trevor Hobbs (Locata Director of R&D).

The Air Force Institute of Technology (AFIT) and Locata Corporation have signed a Co-operative Research & Development Agreement (CRADA) to build and demonstrate new Locata multipath mitigation technology for use in GPS receivers. This cooperation is expected to leverage many years of proprietary Locata ground-based technology development to bring completely new capabilities to satellite-based GPS receivers, AFIT said.

Northrop Grumman to Offer Improved GPS-Challenged Navigation and Geo-Registration Solution for U.S. Air Force

July 9, 2013By

Northrop Grumman Corporation has been awarded a phase two inertial navigation system-related contract from the Air Force Research Laboratory to continue improving geo-registration accuracy for positioning and pointing applications, even in GPS-denied conditions. Geo-registration of data is critical for accurate interaction between systems, such as locating targets and handing off coordinates to another aircraft. Geo-registration of images involves pairing unreferenced... read more

Following the Team into Danger

June 1, 2013By
Ma-opener

When a team of firefighters, first responders, or soldiers operates inside a building, in urban canyons, underground, in foliage, or under the forest canopy, the GPS-denied environment presents unique navigation challenges. An enhanced personal inertial navigation system (ePINS), based on a strapdown navigation solution using a mid-grade IMU and wavelet-based motion-classification algorithms, can track positions with errors of less than 2 percent of distance traveled in both indoor and outdoor environments. read more
