Combined Use of GPS and LORAN-C in Integrated Navigation Systems

Abstract:	In 1995, the Avionik Zentrum Braunschweig (in close co-operation with the Technical University of Braunschweig) has carried out a study to investigate the potential of a combined usage of GFS and LORAN-C in close co-operation with the German MOT, DFS and LBA [l]. One major motive for this effort was that many states and organisation feel the need for a terrestial back-up navigation system for the existing satellite navigation systems like GPS or GLONASS. This study has been funded by the German Ministry of Defense (MOD) and focused on an investigation in respect to user-requirements, certification and operational as well as institutional aspects. Another major emphasis was taken on a theoretical analysis of a combined GPS/LORAN-C navigation solution with respect to the special Northwest-European environment. As a result, an algorithm based on raw-data from GPS as well as LORAN-C has been developed and tested in a number of simulations. In a second phase of this project, three different pilot-projects for air, land and marine will be defined and all theoretical results carried out in this first phase will be comprehensively tested in real environments in a number of experiments.
