With the help of man’s best friend, Honeywell Aerospace will demonstrate its surface navigation technology at this year’s Association of the U.S. Army (AUSA) Annual Meeting and Exhibition. During the show, a dog will wear a utility pack containing the compact navigation unit as it roams the exhibition floor with its handler. Visitors to the Honeywell booth at Hall A – Booth 1831 will be able to follow the dog’s journey on a standard display.
The point of this unique demonstration is to showcase the effectiveness of a navigation system that works even when Global Navigation Satellite System (GNSS) or GPS signals are unavailable, jammed or unreliable.
The GNSS Denied Surface Navigator (GDSN) uses a proven Honeywell micro-electromechanical Inertial Measurement (MEMS) Unit (IMU) and Doppler radar sensors to pinpoint the location of soldiers, vehicles, or canines and is capable of providing accuracy levels of better than one percent of distance travelled. For example, after travelling for 100 meters, the accuracycan often be better than 1 meter.
Since the technology doesn’t rely on GNSS signals, it’s ideal for challenging environments such as urban canyons, indoors, tunnels, caves, or areas such as forests and agriculture landscape where GNSS can be intermittent but accuracy is needed. The GDSN maintains accuracy levels even when its wearer makes nonstandard motions such as crawling, jumping, running, or loitering.
The GDSN can be configured with an IMU that matches the mission’s accuracy needs. While a system for a vehicle may require a higher performance IMU, a system customized for dismounted soldiers and canines may be configured with lower-cost components.
Honeywell continues to work on meeting customer requirements for GDSN products and is currently gathering feedback from potential users of the technology in the military and several other industries.
