The ATV is manually controllable all over its Final Translation reference trajectory äDistributed simulation using HLA provides a good opportunity for remote control of vehicles: e.g. even during the last 3-4 months before the flight when they are not any more authorised to travel, the astronauts could receive an adequate training on ATV control and monitoring its approach from a remote locations (USA, Russia,…) äDistributed simulation using HLA appears to be a good solution for interactions such as “trainee - instructor” and “crew - ground controllers” äFrom the cost point of view, implementation of a distributed simulation system could help save considerable budget by reducing amount of hard- and software to be exchanged between partners Mission Rehearsal & Training : Lessons learned
