Global Navigation Satellite Systems Engineering, Policy, and Design
Robustness to GPS jamming and spoofing is critical for military applications yet challenging, and numerous alternative sensing techniques have been explored over the years. Virtual aiding methods have proven effective, with the ability to constrain and localize the search space for improved operability in GPS-denied environments.

U.S. military efforts to field jam-resistant GPS weaponry not only run behind schedule, they continue to fall back, according to the annual report from the Department of Defense (DoD) Director, Operational Test and Evaluation (DOT&E) Nickolas Guertin. Because “the lack of M-code capable receivers limits the M-code use by U.S. and allied warfighters,” branches of the Armed Forces are now sourcing directly from commercial suppliers.

The Air Force Research Laboratory’s complementary PNT AgilePod prototype aced its first high-dynamic flight tests in November 2021. It also achieved two other firsts: the first test of fully-remote interfacing and alt-PNT data transmission, and the first demonstration of overland/overwater transition performance.

Russia conducted an unannounced direct-ascent anti-satellite (DA-ASAT) missile test on November 15, targeting and exploding its own defunct satellite Tselina-D. After the test, Russian television executive and spokesperson Dmitry Konstantinovich Kiselyov, head of the official Russian government-owned international news agency Rossiya Segodnya, reportedly said on live tv that this demonstrated that Russia could and would if necessary target U.S. GPS satellites, thus “blinding” its military forces.
