ACCURATE DETERMINATION OF SHIP'S VELOCITY USING LORAN-C

Loran-C can be used to determine ship velocity with an rms uncertainty of several centimeters per second in 5-minute averaging intervals. Range rates obtained from linear least-squares fits to the ranges from several stations are used in a second spatial least-squares fit to determine east and north velocity components. The combination of master independent range-range operation and cross-chain operation has greatly increased the usual Loran-C operational area by allowing operation between chains.
