Abstract
Missions towards NEO (Near Earth Object) are one of the most interesting research opportunities in space exploration. The GNC (Guidance Navigation and Control) system in the terminal phases is one of the enabling technologies of NEO missions. A high fidelity simulator is needed to provide a realistic mission environment to foresee the behavior of the satellite with the dimensioning of sensors and actuators, the verification of system requirements and the evaluation of the performances of the GNC systems. GMV has developed a suite of tools to test and validate different mission scenarios: a kinetic impact, the rendezvous phase, the proximity operations and the descent and landing. The design of the autonomous GNC system for the terminal phase is highly mission dependent (target characteristics, arrival geometry and kinematics, SC (Spacecraft) configuration). The optimal combination of sensors, algorithms, and actuators cannot be selected with a qualitative trade-off because of the complex dependence of the performances with respect to the GNC parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
