New PNT and navigation technology from Northrop Grumman helps F-22 sharpen aerial combat capabilities

Oct. 15, 2020
Accurate PNT can help pilots determine precisely where they are in relation to surrounding threats, and determine how much they are accelerating.

WASHINGTON – The success of high-speed air-to-air combat rests on a pilot’s navigation ability to know a plane’s exact location, movement patterns, and angle of attack. Kris Osborn at Warrior Maven reports. Continue reading original article

The Military & Aerospace Electronics take:

15 Oct. 2020 -- This kind of aerial combat relies on secure navigational systems such as GPS and inertial navigational technologies.

Yet GPS also is known to be vulnerable to hacking, jamming, and various kinds of enemy intrusion. The risk of having combat maneuvers and tactics compromised continues to inspire widespread Pentagon efforts to harden GPS and establish alternative guidance systems.

An emerging shoe-box size navigation capability -- the Northrop Grumman Embedded Global Positioning System/Inertial Navigation System-Modernization (EGI-M) -- is being developed to address these challenges and vastly strengthen positioning, navigation, and timing (PNT) parameters.
