State of the Art -Bulky, 20-lb boxes in 1991 -Today, PLGR (plugger) is portable, durable -Precision Lightweight GPS Receiver -1 per company (180 soldiers) in Desert Storm -Now, 1 per squadron (9 soldiers) Can FRS 142 outmaneuver the Army?
Gulf Wars – GPS Advancement DESERT STORM Reports via radio, plots on paper map 9% precision guided Time lapse pinpointing targets Strategic navigation IRAQI FREEDOM GPS radio automatic, digital screen maps 70% precision guided Target coordinates acquired via GPS Tactical Navigation
Achilles’ Heel? Dependence on technology What if it can be taken away? –Jamming –Spoofing –Hacking Double edged sword –Public availability
Jammers in Iraq “If a country has a Radio Shack, it will have a jammer.” Russian jammers –Can block signal acquisition from 124 miles away, clear LOS –But not once the signal has been acquired The bomb still falls.
Counterjamming Jammer emits a signal = death “nulling” antenna arrays G-STAR redirects the missile’s receiver Ground troops more crude
The Double Edged Sword Whose GPS is it, anyway? A competent opponent could use it against us Indeed, could FRS 142 defeat an army? –Turn off selective availability But still fairly accurate –Not enough for a cruise missile, but so what? Some encoding is possible
Galileo Lives Europe’s bitter –Want their own 30- satellite constellation Problems –Greater availability to the enemy –Access not restricted at all Top notch accuracy
Benefits and Dangers Top benefit: 95% urban availability –Currently more like 55% Top danger: availability to enemy forces –Even Europe could become the enemy –China might get involved… Current solution: –Gripe about it and beg Europe not to do it My Solution: Satellites with missiles to shoot down the enemy GPS satellites.
FUTURE Complete battlefield digitization –Force XXI Battle Command, Battle and Below (FBCB2) Soldier as a complete unit –Land Warrior
FBCB2 Touch screen battle control Total battlefield awareness Elimination of friendly fire
Digitized Divisions 2001 Exercises at Fort Irwin –Red Team falls to digital Blue Team IV Infantry Division –Almost saw fighting in Iraqi Freedom
Land Warrior Completely integrated soldiers Urban combat advantages Most deadly soldiers in history Fewer troops needed, fewer troops lost
