This paper comprises an overview of the research performed into DGPS guidance for helicopter approaches to offshore installations, followed by three parts containing unabridged versions of the three volumes of the Cranfield University final project report (ref. CA/CSG/7052 Issue 1, dated 01 November 1999). The first volume, ‘Experimental Procedures’, describes the three measurement systems utilised, the data recorded and the experimental procedures employed for the trials. The second, ‘DGPS Equipment Performance’, covers the extraction of the helicopter ‘truth’ position reference using post processed GPS measurements, compares the real time Differential GPS (DGPS) position data with the ‘truth’, and discusses the various factors which were found to affect the availability and accuracy of the real time DGPS data. Volume 3, ‘DGPS Approach Guidance’, reports on how the approach guidance information was generated and presented to the pilots and discusses the flyability aspects assessed.
