Yes ...it is. It's cold INS (Inertial Navigation System). It uses a set of accelmeters for all 3 axes. Even in the 70' was quite acurate and was used for guiding planes. Was mostly replaced by GPS but modern variants (few Y old) are more accurate then civilian GPS.Misc said:Is there an alternative for GPS?
