Air Force PC-1000 cameras have been engaged in satellite observation for geometric geodetic position determinations since September 1963. First results with ANNA 1-B data were published by the Air Force Cambridge Research Laboratories in 1964 and again early in 1965. The findings presented here were obtained with satellite observational data from two Air Force projects observing the ANNA 1-B and GEOS-A flashing light, geodetic satellites. The latest analytical photogrammetric methods are used in the ACIC photographic plate mensuration and reduction methods and are described herein. The satellite triangulation adjustment procedures programmed at ACIC are defined along with the solutions of simple test triangles and the more complex positioning of the Island of Trinidad with respect to the North American and Cape Canaveral Datum in southeastern United States. A 30 foot spherical standard error accuracy figure was achieved in positioning Trinidad relative to the Florida triangulation. The PC-1000 camera system has proved to be an accurate measurement device for geodetic positioning and should be used to satisfy future requirements for geodetic ties and otherwise strengthening geodetic control. Specific recommendations for future use include the densification of the PAGEOS World Net and the extension of the Trinidad tie downrange to the Eastern Test Range island sites of Fernando de Noronha and Ascension.
