GCOD allows users to design and optimize a walker constellation or a formation flying mission. Access to a specific area or to specific ground station(s) will be maximized, minimizing the number of required satellites.
Thanks to the reduction of launch costs, the amount of satellites on orbit is growing quickly. New companies arise and develop new ways of using the space asset. This is mostly due to the design of new cheaper rocket launchers and to the satellites mass production. Therefore, the budget required for a launch is decreasing, allowing the space industries to invest more in the satellite itself. It is not a case if a lot of companies are deploying different kinds of mega-constellations. Moreover, the opening of the space asset to private companies leads to the implementation of less expensive projects, if compared to the previous national space projects.
Looking at this scenario, GMSPAZIO provides a tool dedicated to the study and optimization of satellite constellations. Existing applications are complex and general purpose driven, therefore adapting them to strict requirements needed for the design of a specific constellation is time consuming. Our tool, instead, is aimed to solve this kind of problems offering an easy to use solution.
GCOD supports the developing phase of a project, thanks to its advanced algorithms. It searches for the optimal parameters that fit the operational constraints imposed by the user, such as the minimum number of satellites required to provide coverage to a location or a user defined area. The tool has different modules for different kind of constellation design related problems; it can be used to search for optimal orbital parameters on a single plane or it can optimize an existing constellation, moreover it can aid in the design of formation flying missions.
A satellite constellation is typically composed of several, structurally identical, satellites. If, for any valid reason, during the development of the satellite, a structural change must be introduced, the overall constellation performance will be affected. In this scenario our tool provides a fast feedback about the changes introduced.
GCOD is an application progressively updated and evolved. Release 1 is divided in two parts:
