Development of Remote Sensing Satellite Attitude Visualization Simulator: Mechanical Design

LAPAN already has three satellites in orbit. All the LAPAN Satellites are remote sensing satellite that will send satellite attitude data in real time mode and offline mode. The satellite attitude data is very important in a remote sensing satellite mission. For example, in the digital imager mission, operator use attitude data to take the image of targeted area with high accuracy. To make it easier for operators to understand satellite attitude, they need a satellite simulator or satellite mock up that can show satellite attitudes in realtime or offline mode, especially in special missions. In addition, the dissemination division can also use the simulator to educate people about satellites. This paper discusses the working principle of the simulator and the structural design of the simulator. After the analysis, it is obtained that simulator uses the gimbal mechanism. The materials for the structure is 7075-T6 aluminum alloy. Meanwhile, the drive are three 17HS4401 stepper motor in each axis. The 17hs4401 stepper motor is strong enough to rotate all axes and the 7075-T6 aluminum alloy is strong enough and rigid to be used as a simulator structure.
