International Journal of Advanced Science and Technology Vol. 29, No. 6s, (2020), pp. 232-236 An Analytical Search for Efficient Microcontroller-On Board Computer for Veltech-NanoSat 1Prabhu Kumar Surarapu, 2Tumuluri Sree Sravya, 3D.Ruthra Prabha 1Assistant professor, 2,3UG student Department of ECE Veltech Rangarajan Dr.Sagunthala R&D Institute of Science and Technology, Chennai Abstract On Board Computer (OBC) isthe heart of the satellites and particularly, It is the main subsystem in the Nano satellite.OBC is responsible for communication, data storage and functional control between all subsystems in the satellite. Right Choice of micro controller is very important task since complete monitoring of the subsystems depends on the OBC. The probability of the success of the satellite mission depends on the reliability of microcontroller and components. In this paper we have listed down, compared and analysed the microcontrollers that were used earlier in nanosatellites and pico satellites like PRATHAM, JUGNU, SATYABAMASAT, ICUBESAT,STUDSAT and SWAYAM. Key words--- On Board Computer (OBC), Microcontroller, VeltechNanoSat, Nano satellite I. INTRODUCTION Veltech-NanoSat, the first satellite initiative of Veltech group of institutions, Chennai, Tamilnadu,India, is in the process of development at Veltech Rangarajan Dr.Sagunthala R&D Institute of Science and Technology under guidance of Indian Space Research Organisation (ISRO) . This project was initiated with the purpose enabling the students and faculty who are involved with design, analysis and testing. The important mission of this nano satellite is to monitor the agricultural fields, land sliding, forest fire, flow and quantity of water. Like other satellites Veltech-NanoSat has also various subsystems which include Payload, Power, Communication, Attitude control, Structure, Mechanisms, Thermal and On Board Computer (OBC).
