The LaserCAT tool is designed to help you plan the laser illumination of your satellites, missiles, and launch vehicles in a way to cut the risk of accidental illumination of other space objects. Drawing upon a comprehensive satellite database, LaserCAT applies a series of tests to cut candidates for which there is no potential risk of illumination during the user-specified time frame. The user interface lets you specify the properties of the Earth-based laser, including an exclusion half angle that defines a safety cone around the laser beam. The tool identifies space objects that enter the cone during the selected time frame (further limited to times when the laser site has access to the target object) and presents the results of the analysis via reports and graphs giving the entry and exit times of those objects and the times of clear firing. Advanced features allow the selection of alternative databases and provide the option of having potential victims brought into the scenario.
