Oh you bet. Inertial navigation (INS) is found in most large planes and fighter jets as a backup for GPS. In addition some spy planes used to use star positions, sun position, and timers to determine global position. In addition there are ILS, VOR, and ADF radio beacons for most civilian traffic. |
