Both. GPS can be jammed and spoofed fairly easily, but gives very accurate readings. Radar and other instrumentation are much harder to screw with but aren't as accurate.
It's probably a good idea to have local infrastructure in case things turn sour.
All that we really need is perfect inertial navigation, then it'd be a moot point. Amiright?
The black boxes from Return from the stars?
I was thinking more like the dead reckoning navigation used on ICBMs, but sure.
Only issue is that close is good enough for nukes and horseshoes, not necessarily other stuff. ;) I have a friend working on a fancy DoD project to do precision airdrop on the cheap, and they've looked at all sorts of cheapish inertial systems to supplement basic altimeter/GPS/windspeed/etc. measurements. Accuracy is a real challenge, since errors tend to accumulate. Oh, well, I guess we'll have to stick with imperfect solutions for now.
If you want to be able to defend against a second 9/11 you need radar. GPS needs an active component on the plane, radar doesn't.
That's actually only true for searching radars. Tracking radars are more accurate than GPS. At Oerlikon we could even hit as small objects as a mortar shell.Quote:
