Precision Aircraft Navigation Based on Loran-C and Digital Altimetry

Abstract

The report describes a system that can provide precision aircraft navigation based on Loran-C and digital barometric altimetry. The system is expected to be capable of fulfilling the critical accuracy requirements of the terminal area as well as serving the needs of area navigation. A digital barometric altimetry technique is described, which has sufficient accuracy to provide the third dimension for all phases of aircraft flight. Further, several auxiliary functions are described that are made practicable by high-accuracy positioning. These are: on-board determination of the point to release an object for free fall to the ground, a built-in approach and departure system, and automatic direction finding.
