GMPT – GMSPAZIO MISSION PLANNING TOOLKIT
GMPT is a software package fully customized to help end user during Mission Analysis and Contact Schedule generation activities for the Ground Segment.
Among the several issues characterizing space operations management, there is the need to optimize the utilization of the ground antennas for data uplink/downlink.
The Ground Station activities are usually planned either manually (by selecting one contact at time) or through scheduling algorithms that don’t assure global optimization, but this doesn’t guarantee the implementation of the best suitable strategy, especially in case of a network of Ground Stations that must serve a constellation of satellites. By maximizing the number of accesses for each available antenna user can:
- reduce costs (by reducing the number of antennae needed to accomplish a certain service), improve efficiency (by securing backup links in case of failure)
- maximize the profits (customers normally pay on the basis of the number of contacts)
The proposed approach is based on a multi-algorithm approach (to take into account both global and local requirements and constraints); it is flexible enough to allow the customization of any set of conflicts within the considered time span and is capable to generate a conflict-free contact plan by following a multi-objective cost function (nominally based on the priority assigned to each contact and to the duration of the contact itself).
