Northrop Grumman Test Flies Jam-Proof GPS
Northrop Grumman says it’s successfully flight tested a jam-proof navigation system to replace the current gear on military aircraft. Embedded Global Positioning System (GPS) / Inertial Navigation System (INS) Modernization, known as EGI-M, was installed on a Cessna Citation and put through its paces in May. The core of the system is something called an M-Code capable GPS receiver that can “quickly transmit positioning, navigation and timing information” in “GPS-contested and GPS-denied… (www.avweb.com) More...

But couldn't get funding at that time so I moved on. A company is presently working on such a system using objects akin to Quasars and other high emissive stellar objects as types of beacons.
Stole that article direct from Avweb.
If you are talking about my message I still have my SBIR filings from the 2002-2004 time frame
No. I was commenting that, when I clicked on the FlightAware link, up popped an Avweb page.
That's because it is a link to avweb. Every single squawk posted is a link to a website that is external to FA. FA doesn't generate any news - it only gives us a place to discuss.
