Abstract:	Loran-D is a highly accurate pulsed hyperbolic navigation system similar to and compatible with Loran-C, but designed for military tactical use. The helicopter-transportable-transmitter stations have quickly erectable antennas using new tower technology. A signal range over half that of Loran-C is achieved by the fortunate propagation characteristics of 100 KHz waves, by a modified compatible signal format and by improved transmitter solid state technology. Deployments of the stations in the U.S. and Europe are described. The potential uses of Loran-D include: gap filler in Loran-C coverage, a transportable survey system, and long range navigation coverage for many civilian applications.
