A Loran-C based receiver for automatic vehicle location

36th IEEE Vehicular Technology Conference, 1986
A receiver which uses LORAN-C radionavigation signals to compute relative time delays and hence location is described. The receiver interfaces to a two-way mobile radio and uses the existing RF channel to send its received LORAN-C information to a fixed-end computer for further processing including location calculation and display.

DATATRAK automatic vehicle location and position reporting system

Conference Record of papers presented at the First Vehicle Navigation and Information Systems Conference (VNIS '89), 2003
This system is designed specifically for land use, although equally efficient on boats and aircraft, particularly helicopters. Hyperbolic radio location is used with low-frequency transmitters spaced at 150 km intervals. Time division multiplexing permits up to 32 transmitters on one pair of frequencies. A one-way data system synchronized to navigation
