A controller 200 (e.g. satellite attitude determination and control system ADCS, or orbit determination and control system ODCS) for an aircraft or spacecraft, the controller 200 controlling real time processes during normal operation in flight/in orbit; the same controller further simulates operations prior to launch/take-off. The controller may be a multi-core processor 200, in which core 310 may control the craft in real time during normal operation; and core 320 may simulate processes before launch/flight. Cores 310, 320 may run different operating systems, core 310 running a real-time OS. Dynamic modelling of the aircraft/ spacecraft/ satellite may be implemented during simulation. The controller may have actuators (e.g. reaction wheels, momentum wheels, torque rods, magnetorquers) and sensors 330 in a control feedback loop. During normal operation, core 310 may command 404 actuators based on received sensor signals; during simulation, core 320 may output synthetic measurements 403 based on dynamic model of the craft.
