Observation planning device, observation planning method, and observation planning program

摘要

In an observation system for observing the ground surface or the like by a sensor mounted on a navigation body, an efficient observation plan can be generated when a wide range of observation requests are given. An observation opportunity specifying unit 22 specifies a plurality of orbital paths that can observe an area within the observation range based on an observation range indicated by an observation request and an orbital calendar of a navigation body, and for each specified orbital path. Then, by changing at least one of the scanning direction and the off-nadir angle, one or more observation scenes for observing the region in which the number of observation scenes to be combined is minimized are specified. The observation plan determination unit 23 determines a combination of observation scenes in which the observation range can be observed as an observation plan. [Selection] Figure 1
