With increasing maritime activities such as logistics and leisure, the frequency and scale of maritime accidents are growing. To minimize damage from maritime accidents and provide appropriate responses, the accident scenarios must be accurately predicted. To this end, maritime control and monitoring systems are required. Recently, remote sensing platforms such as drones, helicopters, and satellites have been increasingly used for accident monitoring. Images obtained by drones or helicopters have high resolution but small coverage because the platforms fly at a low altitude. In comparison, the images acquired from satellites, which operate in high orbits, have wide coverage and are thus more effective in monitoring vast maritime areas. However, because satellites capture images at a predetermined time according to the mission orbit, the observation period is limited. Therefore, a satellite imagery collection system based on satellites operating worldwide must be established to acquire images from the target time and place. This paper proposes an image collection system for acquiring satellite images of target areas in maritime accident scenarios. Based on a statistical analysis of historical maritime accident data, the main objects to be detected are selected, and the requirements are specified. Additionally, the spatial and revisit cycles and observation time of optical and synthetic aperture radar satellites are analyzed and an image collection system is established by selecting the satellites available for accident response. The proposed system can facilitate the use of satellite images to respond promptly to maritime accidents.
