This is coolbert:

More HIMARS stuff Ukraine. From the Internet web site Strategy Page and thanks to same.

Improved HIMARS using guidance that is impervious to Russian jamming of GPS signals.

"Marines: Ukraine Tries Marine Improvisation"

HIMARS performance in a GPS jamming type of environment still excellent.

"June 9, 2022: Ukraine is the latest user of the American HIMARS (High Mobility Artillery Rocket System) vehicles that carry six GMLRS (GPS/INS guided MLRS). Ukraine knew of the success of the HIMARS vehicle and the capabilities of the GMLRS rockets. The latest version of the rocket can hit targets up to 85 kilometers [about fifty-two miles] away using INS/GPS (Inertial Navigation System/Global Positioning System) guidance. The INS component is important because it takes over if the GPS signal is lost due to jamming or when mountainous terrain blocks GPS as the rocket approaches the target


[HIMAS guidance] "GPS (plus a backup INS/inertial guidance system) to find the target location it was programmed with. With GPS the GMLRS will land within a few meters [yards] of the GPS coordinates. If the INS has to be used, that triples to about ten meters [yards]. In 2008 the army tested GMLRS at max range (about 85 kilometers) and found that it worked fine."

INS: "I have been traveling from a starting point in this direction at this speed for this amount of time. I should now be here!"

Russian ability to jam battlefield GPS signals considered to be FORMIDABLE? We shall see!
