Embedded Global Positioning System (GPS) Inertial (EGI) Navigation System (U)

Overview (U):

(U) The Embedded GPS Inertial Navigation System (EGI) is a navigation system which combines a GPS receiver card with an Inertial Navigation System (INS) in an integrated single until of modest size and weight (7 x 11 x 11 inches and weighs 20 lbs). EGIs from Litton Avionics and Honeywell Inc have now completed QT&E. They are being integrated in both rotary and fixed wing aircraft as an upgrade to existing systems or a replacement for older and less capable systems.

Description (U):

(U) None.

User Impact (U):

(U) The EGIs from Litton and Honeywell are the first widely used combined INS/GPS units in DoD aircraft. They integrate the latest GPS receiver technology with a modern strapdown INS to provide highly accurate all altitude, all weather navigation and timing information to the aircraft allowing more precise flight pattern, rendezvous, and weapons delivery.
