Abstract: A system and method for geo-referencing a main measuring instrument which operates in an Instrument Coordinate System. The method includes the steps of deploying the main measuring instrument on a deployment surface. An auxiliary measuring instrument is used to measure the position of a plurality of external reference points in a Master Coordinate System as well as a plurality of local reference points on the main measuring instrument in the Master Coordinate System. An inclinometer associated with the main measuring instrument, obtains an orientation reading for the deployed main measuring instrument. A processor then uses the orientation reading and the measured positions of the external reference points and the local reference points on the main measuring instrument, to geo-reference the main measuring instrument so that measurements made therewith are automatically output in the Master Coordinate System.

Abstract: This invention relates to an ammunition loading assembly (10) for loading a projectil (12) into a barrel (14) of a gun comprising an urging member (16) for urging the projectile (12) into the said barrel (14). The assembly (10) further includes a drive means (18) for driving the urging member (16) between a projectile receiving position outside the barrel (14) and a projectile delivery position inside the chamber (20) of the gun. The drive means (18) includes a drive chain assembly (22), for driving the urging member (16) between the projectile receiving and delivery positions. The drive chain assembly (22), is rigid in all directions but one, the arrangement being such that the drive chain assembly (22) pushes the urging member (16) from the projectile receiving position to the projectile delivery position and pulls the urging member (16) from the projectile position to the projectile receiving position.
