GPS is important to the military, but many modern combat systems can get along without it. Most systems that use it have some manner of backup.
GPS in combat debuted during the Gulf War, but mostly as a backup for navigation rather than targeting. We did not have 100% coverage back then, all of the satellites were not up yet.
- AstralStorm 3y agoYou did have 100% coverage back then, but not high quality all of the time. In some rare cases only a single satellite pseudofix would have been available. That can still be accurate if the location device carries a decent synchronized clock. IOC was defined as always being in sight of 3 or more satellites, plus maintenance capability. That was achieved in 1993.
- ianburrell 3y agoThere are reports from Ukraine of guided shells not working when GPS is jammed. I thought that most guided munitions have inertial guidance and GPS was to improve accuracy but maybe that doesn’t fit in artillery shell. I was reading that with MLRS that the launch location can be entered manually.
