- moffkalast 3y agoIt's some serious irony that after all technological advancements we are returning to the very first naval navigational principle, dead reckoning.
- lxgr 3y agoIs it that ironic? Self-contained navigation has always been a priority in aviation, for fairly obvious reasons (safety, i.e. not having to depend on the complex external single point of failure that GNSSs are, and security, i.e. GNSS spoofing). Planes were using INSs long before GPS to navigate across oceans, but even today, they're required to carry several instances of each (GPS and INS, in addition to ground-based systems) for redundancy.
- cf100clunk 3y agoSolid-state, read-only, shielded inertial navigation systems have been around since the 1950s. Is there anything more than incremental improvement to that technology at this point?
