A joint research project between the University of Newcastle upon Tyne
and City University is developing a prototype system for using kinema
tic GPS techniques to derive the exterior orientation of an oblique se
nsor without the use of co-ordinated ground control. This paper presen
ts an overview of the techniques employed in deriving GPS antenna co-o
rdinates and their subsequent use in finding the required orientations
. The latest results and future plans are presented and discussed.
