The satellite requires the support of a robust sub system. On Board Data Handling (OBDH) is the core function of the satellite subsystem and has to be error free in managing the operation of the satellite. It should withstand the harsh environmental conditions in space that has a lot of hazards caused by radiations. In view of these two conditions, the OBDH design should be able to manage the operation and overcome the hazards of radiation. In order to manage the operation Real Time Operating System (RTOS) was applied. RTOS was able to manage the task efficiently and effectively. In the aerospace domain, RTOS has become popular because of its strength in managing the operating system. Error Detection and Correction System (EDAC) system was applied to make OBDH more robust. This paper will discuss the implementation of the EDAC system in tandem with the RTOS behaviour to manage the operation and increase the robustness of the system. The findings show that OBDH can be programmed successfully using RTOS to handle critical and robust operations.

INSPIRE (Indonesian Nano-Satellite Platform Initiative for Research & Education) is a nonprofit initiative project that aims to build & develop a satellite technology platform (nano-satellites in particular) among universities in Indonesia, by placing students as main participants.

INSPIRE project was created to remind that our country is enough left behind by other developing countries in the field of satellite technology, yet this technology platform can support other sectors such as telecommunications, navigation, marine, environmental, natural resource exploration, as well as early warning system for disaster.

INSPIRE project is expected to raise as well as providing transfer media of knowledge and skills as well as to grow and develop interest in the satellite technology (especially nano-satellites) among the students, and the universities as a center of activity.

Certainly, the final goal of this project does not just stop with the nano-satellite in the university & college students only, but is expected to advance satellite technology in Indonesia, because the technology is very vital existence, either in an academic environment as well as in industrial environments (telecommunication & informatics) .

One early milestone INSPIRE project is convening a national workshop, which brought together the stakeholders in the satellite technology in Indonesia, such as Tubsat LAPAN team, IiNUSAT (Indonesian Inter-University Satellite) team, INASAT team, as well as the experts and the entrepreneurs of nano-satellites from abroad. Moreover, it also invited representatives of students and universities throughout Indonesia as a potential major participant in the next INSPIRE activities. This workshop also bring them together in a forum to discuss strategies and synergies in the future for education and mastering of nano-satellite technology for the welfare of the nation.
