- _nezo 5y agoThat sounds interesting. Iirc inertial navigation systems are also a key component in missiles that don't enable radar (and so reveal their presence) until they're right on the target ("pitbull"). I don't know how much of a limiter the INS is there, but it could possibly lead to more precise missiles with less warning time.
- sandworm101 5y agoMissiles yes, but it is more practical for submarines. More accurate submarine navigation means they can navigate closer to the bottom/coast without using sonar and can fire ballistic missiles accurately without surfacing.
- cabalamat 5y ago> Quantum accelerometers theoretically enable hyper-accurate guidance systems immune to external jamming Can one jam normal accelerometers? I don't see how.
- yjftsjthsd-h 5y agoI think it's rather that normal accelerometers aren't precise enough to replace GPS (well, radio/satellite based positioning systems), which are possible to jam.
- naniwaduni 5y agoNormal guidance systems, which rely on non-accelerometer input, are vulnerable to external jamming.
- cabalamat 5y agoCertainly GPS is, but I don't see how inertial or celestial are.
- sandworm101 5y agoCelestisl is impractical for modern weapons. INS just isnt accurate enough over long periods (think of subs submerged for months).
- cabalamat 5y ago> Celestial is impractical for modern weapons. My understanding is ICBMs use it. It could be used by UAVs to get within a few miles of the target, and then use visual / IR / radar to to get to a more precise location.
