COMMERCIAL-OFF-THE-SHELF INFRASTRUCTURE FOR A 1U CUBESAT

Abstract

CubeSat nanosatellites use a standardized chassis format to permit low-cost space missions through the use of standardized components and launch systems. However, many CubeSat missions still cost far too much due to the use of costly “space-rated” components. This project focused on the development of a sub-$5,000 CubeSat through the following techniques: 1. Use of consumer-off-the-shelf (COTS) components. Space-rated and custom microcontrollers, radios, and other components carry a very hefty price tag. COTS components are commercially available and therefore much less expensive. 2. Use and validation of a miniature HAM radio for communications. HAM radios are regularly used for the communications systems in CubeSats, but they are usually custom-made. 3. Use of 3-D printing for the internal structure, which has great potential for cost and mass savings. 3-D printing permits greater creativity in design than the standard stack format. The satellite will gather data, record temperature and orientation telemetry. It utilizes COTS components including a Yaesu VX-3R amateur HAM radio, a Teensy 3.2 microcontroller, and an Arduino MicroModem, in addition to a 3-D printed internal structure.
