Recent Developments in the "TERPROM" Integrated Navigation System

Alan J. Robins

Abstract:	The British Aerospace "TERPROM" system is briefly introduced, and the operation of the "continuous mode" Kalman filter is explained. The advantages of TERPROM as a navigation system are summarised, and its performance over flat ground is assessed. A number of ways of enhancing the TERPROM technique are in traduced, such as the addi tiona! use of Doppler, Scene Matching or GPS data, and the resultant improvement over flat ground is demonstrated. Alternative forms of TERPROM - which do not rely on the use of an Inertial Navigation System are described, and it is shown that performance with these reversionary modes is equally reliable. Finally a new navigation system known as BRAINS The British Aerospace Integrated Navigation System is introduced. This new system has the advantages that: it does not rely upon any one sensor to perform the basic navigation; sensors can be added or removed at will, with a minimum of interference; and tests for integrity and sensor reliability can conveniently be carried out.
