An Analytical Search for Efficient Microcontroller-On Board Computer for Veltech-Nanosat
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). -

With this new issue we bring to you new ideas fresh off the boat along with some new additions from the Editorial Team. We are grateful to all the boys who have contributed their articles for this issue and it is our humble request that you continue to do so. Writing, unlike many other art forms, is unique. It single- handedly tests the many abilities and overall calibre of an individual. I believe that all the boys whose articles you shall now read, ranging from the Primary students upto the Senior students, all have managed to push themselves to their individual limits and convey to us their thoughts. I sincerely hope that you, dear reader, will enjoy reading this magazine and feel satisfied with it. The third issue will be the last issue of the 'Among Ourselves' magazine for this year and our plan is to make it the larget issue till date, but we cannot achieve this feat without your support and contributions.

(2016): JoSS, Vol. 5, No. 3, pp. 483–511 (Peer-reviewed article available at www.jossonline.com) www.DeepakPublishing.com www. JoSSonline.com A Methodology for CubeSat Mission Selection Luis Zea, Victor Ayerdi, Sergio Argueta, and Antonio Muñoz Universidad del Valle de Guatemala, Guatemala City, Guatemala Abstract Over 400 CubeSats have been launched during the first 13 years of existence of this 10 cm cube-per unit standard. The CubeSat’s flexibility to use commercial-off-the-shelf (COTS) parts and its standardization of in- terfaces have reduced the cost of developing and operating space systems. This is evident by satellite design projects where at least 95 universities and 18 developing countries have been involved. Although most of these initial projects had the sole mission of demonstrating that a space system could be developed and operated in- house, several others had scientific missions on their own. The selection of said mission is not a trivial process, however, as the cost and benefits of different options need to be carefully assessed. To conduct this analysis in a systematic and scholarly fashion, a methodology based on maximizing the benefits while considering program- matic risk and technical feasibility was developed for the current study. Several potential mission categories, which include remote sensing and space-based research, were analyzed for their technical requirements and fea- sibility to be implemented on CubeSats. The methodology helps compare potential missions based on their rele- vance, risk, required resources, and benefits. -

Kopacz June 2020 Advisor: Dr. Jason Roney ©Copyright by Joseph R. Kopacz 2020 All Rights Reserved Author: Joseph R. Kopacz Title: Satellite Constellation Deployment and Management Advisor: Dr. Jason Roney Degree Date: June 2020 Abstract This paper will review results and discuss a new method to address the deployment and management of a satellite constellation. The first two chapters will explorer the use of small satellites, and some of the advances in technology that have enabled small spacecraft to maintain modern performance requirements in incredibly small packages. The third chapter will address the multiple-objective optimization problem for a global persistent coverage constellation of communications spacecraft in Low Earth Orbit. A genetic algorithm was implemented in MATLAB to explore the design space – 288 trillion possibilities – utilizing the Satellite Tool Kit (STK) software developers kit. STK and MATLAB autonomously develop and analyze a variety of constellations by permutating altitude, inclination, number of satellites, number of planes, and Right Ascension of the Ascending Node (RAAN).
