Abstract:

Four GPS receivers including the Plessey PA9052, Ashtech XII, Trimble TRIMPACK and Magellan NAV1000M were evaluated for performance and suitability for the positioning and pointing of artillery. Specifications for accuracy in positioning and pointing, an defined by STANAG 2373, are 17.5 metres CEP and 0.60 mils, respectively. The receivers were evaluated for static positioning, short and mid-range 11km way-pointing bearing determination, differential positioning and way-pointing, kinematic positioning and general receiver characteristics. The evaluations were carried out in March of 1991 and while Selective Availability SA was not implemented. Static positioning without SA met artillery specification. Bearing determination to a given waypoint, both short and mid-range, was 3 to 5 degrees but improved under differential GPS processing to better than 0.1 degree. Kinematic survey yielded indeterminate results. The use of differential GPS under good satellite geometry conditions and with adequate observation times may be a feasible solution for the artillery survey positioning and pointing requirement. other techniques employing GPS which show potential for this application are also discussed.
