CubeSat Background

• Pico-satellite 10 cm cube with a mass of up to 1
  kg.
• The CubeSat Project was developed by California
  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)

UMsat UMass Amhersts 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.

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.
