Abstract An aerial survey image capture system for a survey aircraft is disclosed. The aircraft is navigable using 5 navigation parameters that include altitude, speed and direction. The system comprises a camera system arranged to capture successive images of ground beneath a survey aircraft. The camera system has associated camera parameters indicative of image capture characteristics of 10 the camera system, and a loss of separation (LOS) avoidance system for a survey aircraft. The LOS avoidance system is arranged to receive information indicative of the location and movement of the survey aircraft and to receive information indicative of the location and 15 movement of a nearby aircraft in the vicinity of the survey aircraft, determine a predicted closest point of approach (CPA) distance between the survey aircraft and the nearby aircraft based on the received location information, compare the CPA distance with a defined 20 minimum separation distance corresponding to a loss of separation (LOS), and determine an estimate for at least one navigation parameter of the survey aircraft that is required for the CPA distance to remain above the defined minimum separation distance. The system further comprises 25 a camera parameter modifier arranged to produce modified camera system parameters in response to the estimated at least one navigation parameter, the modified camera system parameters modifying characteristics of image capture by the camera system so as to at least partially compensate 30 for a change in survey efficiency when the estimated at least one navigation parameter is used to navigate the survey aircraft.
