  2. CubeSat • CubeSat Background

  3. CubeSat Background • Pico-satellite: 10 cm cube with a mass of up to 1 kg. • “The CubeSat Project wasdeveloped byCalifornia Polytechnic State University, San Luis Obispo and Stanford University's Space Systems Development Lab. The CubeSat program creates launch opportunities for universities previously unable to access space.” (cubesat.org) • Upon completion, university satellites are placed in a jack in the box device developed by Cal Poly called, the “P-POD” (Poly Pico Satellite Orbital Deployer). The P-POD is carried into space on retired Soviet Ballistic Missiles, and then the P-POD jettisons the satellites into space at the proper orbit. • “Students, through hands on work, will develop the necessary skills and experience needed to succeed in the aerospace industry.” (cubesat.org)

  4. UMsat: UMass Amherst’s first student built satellite • UMsat Mission Statement UMsat, founded in 2007 by University of Massachusetts Amherst undergraduates, will provide a platform for students to design, build, test, and launch pico-satellites into orbit. UMsat fosters the development of leadership skills, project commitment, and teamwork, while preparing its members for future careers in the aerospace industry. • Scientific Goal The technical challenges that UMsat will tackle are to develop an Electronic Power System, a Communication System, an Attitude Control and Determination System, and a Data Processing and Management System. The amalgamation of these subsystems will facilitate the successful transmission of a picture of Earth taken by an onboard camera, along with the logging and transmission of health and performance data of the satellite subsystems.

  9. DARTSAT Overview • Modularity by design

  10. Overview of UMsat

  11. MNTMAN I • Timeline

  12. Proposed Timeline • Fall 2007- Fellowships with MASGC (Massachusetts Space Grant Consortium) • Define project scope. • Get necessary seed funding to pursue CubeSat • Develop Electronic Power System (EPS) hardware/software • Winter/Spring 07-08 • Continue engineering education in satellite systems • Purchase complete CubeSat Kit, including all other satellite hardware and ground station equipment • Develop working communication system, powered by previously developed EPS. • Assemble ground station, practice communicating with known satellites.

  13. Proposed Timeline (Cont’d.) • Summer 2008- Fellowship with MASGC. • Test Systems on tethered balloon • Attitude Determination and Control System (ADCS) • Fall 2008 and Spring 2009 – Senior Design Project • ADCS • Design payload • Successfully transmit and receive payload data via high altitude balloon • Create world wide amateur band network for data reception • Launch satellite and receive data

  14. UMsat Budget • Cost Review

  15. Systems • Mechanical System (MEC) • Power System (EPS) • Communication System (COM) • Data Processing and Management System (DPAM) • Attitude Determination and Control System (ADCS) • Payload • Launch Cost

  16. MEC • CubeSat Kit • Flight Model • Chassis Wall, Base Plate, Cover Plate • Development Board • FM430 Flight Module • External Power Supply • MSP430 Flash Emulation Tool and FM430 programming adapter. • Salvo RTOS software

  17. EPS • System Overview • Solar Panels • Batteries • Hardware

  18. COM • In flight COM overview

  19. Ground Station Block Diagram

  20. COM • Ground Station COM overview

  21. DPAM • System Overview • C Programming Tools

  22. ADCS • Attitude Determination and Control System • The exact science behind our ADCS is yet to be determined. • Initial thoughts are to use hard drive disks as momentum wheels, so that we may prevent tumbling through space. • Particularly helpful if we want to point ourselves toward Earth in order to get a clear picture.

  23. Payload • Payload • Initial ideas are an onboard camera, and also various sensors that will measure the health and also performance of the various subsystems. • This is particularly important since we hope that future UMass students will continue UMsat. • The data that we acquire will help those students build better, more efficient systems.

  24. Launch • ~$40,000
