* '''On-Board In Loop Simulation (OILS):''' In this testing, control law is implemented on actual microprocessor unlike fully software testing. Environmental models, sensor models are still simulated in software. This testing can be done with Simulink, Labview etc.

* '''Hardware In Loop Simulation (HILS):''' In this testing, control law is coded on microprocessor along with actual sensor data. This means environment experienced in space has to be simulated physically, which will bring actual sensor in the control loop test. <br \>
