ABSTRACT (maximum 200 words) The Naval Postgraduate School’s (NPS) first CubeSat, NPS Solar Cell Array Tester (NPS-SCAT), will be the foundation for future advances in CubeSats at NPS. NPS-SCAT demonstrates the capability of the CubeSat form factor as a technology test bed for a single experiment – a solar cell tester. This thesis discusses and explains the design, testing, and integration of two full TT&C sub-system for NPS-SCAT. The primary and secondary transceivers will both use the amateur frequency band through an approved AMSAT license. This thesis explains the concept of operations of NPS-SCAT, which drove the data requirements for the TT&C. This thesis also explains the testing of the primary and secondary transceivers and the design, test and integration of the antennas. Finally, this thesis will discuss the TT&C ground station construction, methodology, testing and the frequency coordination access. 14.

Her openness and encouragement of my ideas helped me become a better researcher. Without her excellent advice, patience, and support, this doctoral dissertation would not be possible. I would like to thank all of my committee members, Prof. Jenshan Lin, Prof. Jasmeet Judge, and Prof. Norman Fitz-Coy, for serving on my committee. The committee’s valuable comments and constructive criticism helped to improve this dissertation greatly. I also would like extend my appreciation to the Wireless and Mobile System laboratory colleagues. They always gave me valuable suggestions, generous support, and fruitful “jam sessions” during my graduate studies at the University of Florida.

The number of CubeSats that are being deployed into the orbit has increased in recent years. The design and development have been transformed from traditional hardware devices to software defined radios. However there is a lack of clear understanding and concrete findings on developing proper communication transceivers. The lack of knowledge of proper guidelines to be followed to design and develop communication subsystems prompts and acts as a base for us in understanding the communication subsystem design standards followed by CubeSat projects in various universities.

    CUBESAT MISSION PLANNING TOOLBOX A Thesis presented to the Faculty of California Polytechnic State University, San Luis Obispo In Partial Fulfillment of the Requirements for the Degree Master of Science in Aerospace Engineering by Brian Rand Castello June 2012 © 2012 Brian Rand Castello All Rights Reserved ii COMMITTEE MEMBERSHIP TITLE: CubeSat Mission Planning Toolbox AUTHOR: Brian Castello DATE SUBMITTED: June 7, 2012 COMMITTEE CHAIR: Dr. Kira Abercomby, Assistant Professor COMMITTEE MEMBER: Dr. Eric Mehiel, Associate Professor COMMITTEE MEMBER: Dr. John Bellardo, Associate Professor COMMITTEE MEMBER: Daniel Wait, Lecturer iii Abstract CubeSat Mission Planning Toolbox Brian Rand Castello We are in an era of massive spending cuts in educational insti- tutions, aerospace companies and governmental entities. Edu- cational institutions are pursuing more training for less money, aerospace companies are reducing the cost of gaining flight her- itage and the government is cutting budgets and their response times. Organizations are accomplishing this improved efficiency by moving away from large-scale satellite projects and develop- ing Pico- and Nano-satellites following the CubeSat Specifica- tions. One of the major challenges of developing satellites to the standard CubeSat mission requirements is meeting the ex- ceedingly tight power, data and communication constraints. A MATLAB toolbox was created to assist the CubeSat commu- nity with understanding these restrictions, optimizing their sys- tems, increasing mission success and decreasing the time build- ing to these initial requirements. The Toolbox incorporated the lessons learned from the past nine years of CubeSats' suc- cesses and Analytical Graphics, Inc. (AGI)'s Satellite Tool Kit (STK). The CubeSat Mission Planning Toolbox (CMPT) pro- vides graphical representations of the important requirements a systems engineer needs to plan their mission.

  • MASTER THESIS Mission and Thermal Analysis of the UPC Cubesat
    MASTER THESIS Mission and Thermal Analysis of the UPC Cubesat Pol Sintes Arroyo SUPERVISED BY Josep J. Masdemont Soler Universitat Politecnica` de Catalunya Master in Aerospace Science and Technology 14 de desembre de 2009 Mission and Thermal Analysis of the UPC Cubesat BY Pol Sintes Arroyo DIPLOMA THESIS FOR DEGREE Master in Aerospace Science and Technology AT Universitat Politecnica` de Catalunya SUPERVISED BY: Josep J. Masdemont Soler Matematica` Aplicada I ABSTRACT The Project is envisioned as a mission control analysis and a thermal control analysis of the Cubesat that is planning to launch the UPC (Universitat Politecnica de Catalunya). A Cubesat is a 10x10x10 cm cubic satellite that weights no more than 1 kg and that is currently used in many countries and educational institutions as an easy access to space. The primary work to do would be the analysis of the orbit the satellite would perform. In this way, the STK (Satellite Tool Kit) software would provide the mechanism to perform this analysis. Starting with the known values of the project, simulations have been carried out in order to obtain the trajectory the satellite will would perform. Additionally, perturbations in the orbit, comparatives with other models and simulations with different parameters would be studied. All this practical work is completed with a theoretical explanation of what are the models used by the software, what are the parameters used and why we use this ones and no other ones. The second part of the project presents the thermal analysis of the satellite. In this section, draft calculations of the thermal balance of the satellite are presented along with simula- tions with the SEET (Space Environment and Effects Tool) module of the STK.
