Evaluation of attitude dynamic module on LAPAN-ITB micro-satellite simulator

A satellite simulator is needed in the development of satellite system and subsystems development, for simulating the conditions of the satellite operation. It is also used in the training of satellite operators. Software-based satellite simulator has been known to reduce the risk and cost of satellite development, mainly since the design validation can be done without having to develop costly hardware. LAPAN-ITB microsatellite simulator is developed mainly using MATLAB software and C programming language. The paper discuss about the evaluation of the attitude dynamics module of the simulator. The evaluation is performed by running several satellite attitude dynamic cases and observing the outputs for physical validity. The results show that the attitude dynamics module has been able to properly simulate the attitude of satellite with 3 orthogonal reaction wheels.
