METHOD FOR DETERMINING THE CAPABILITY OF A SENSOR CONTAINED IN A SATELLITE TO ACCESS A TARGET REGION, AND SATELLITE ACCESSING SYSTEM

The invention relates to a method and a system for determining the capability of a sensor contained in a satellite to access a target region. The position of the satellite is ascertained, the viewing radius of the sensor in the direction of a target reference point in a target region is then determined, the extension of the target region in the direction of a satellite position point is ascertained, and the sensor is determined to be capable of accessing the target region if the distance between the satellite position point and the target reference point in the target region is less than or equal to the sum of the viewing radius of the sensor and the extension of the target region in the direction of the target reference point.
