Abstract
The following research has as main objective to present an space environment simulator in hardware in the loop (HIL) to Nanosats under earth’s magnetic field in low orbit, LEO, developed at the Centro de Referência em Sistemas Embarcados e Aeroespaciais’ laboratories, CRSEA, from Instituto Federal de Ciência e Tecnologia Fluminense, IFF. The satellites need to have an Attitude Determination and Control System (ADCS) to enable them to make maneuvers and corrections on its position during the flight. This attitude control can be passive or active, depending on the mission’s objective. In low orbits, LEO, the earth’s magnetic field has enough intensity to generate forces that will result in torque and rotational movement when interacting with the magnetic fields generated by the own satellite. The simulator is composed of a group of six electromagnetic coils, three axis gimbal, support to fix the nanosatellite inside the gimbal, software to control the coils’ magnetic field and an interface to view the field vector generated inside the coils that correspond in time to the same point of the satellite’s orbit.
