Abstract: A method of providing apparatus comprising: providing a first store and a first payload on or in the first store, the first store being for mounting to the outside of an aircraft; acquiring aerodynamic properties, moments of inertia, and the mass distribution of the first store and first payload; providing a second store and a second payload, the second payload being on or in the second store, the second store being for mounting to the outside of the aircraft, the second payload being different to the first, the second payload comprising a sensor and/or a projecting means; and configuring the second store and the second payload such that the aerodynamic properties, moments of inertia, and mass distribution of the second store and the second payload are substantially the same as those of the first store and first payload.

Abstract: Methods and apparatus for capturing and processing images, the images being of terrain (6), the methods comprising: using each of a plurality of cameras (14, 6, 18, 20), capturing an image of a surface of the terrain (6) thereby producing a plurality of camera images, each camera image comprising a plurality of pixels; registering the camera images, thereby producing a plurality of sets of registered pixels; classifying each set of registered pixels; using a ground penetrating radar (8), capturing a radar image (24) of the terrain (6); performing a detection algorithm on the radar image (24) to detect an at least partially subterranean object or terrain feature (26) in the radar image; and associating the detected object or terrain feature (26) with at least one classified set of registered pixels (28, 30).
