Automated Design of CubeSats and Small Spacecrafts
The miniaturization of electronics, sensors and actuators has enabled the growing use of CubeSats and sub-20 kg spacecraft. Their reduced mass and volume has the potential to translate into significant reductions in required propellant and launch mass for interplanetary missions, earth observation and for astrophysics applications. There is an important need to optimize the design of these spac...
متن کاملRight-sizing Small Satellites
Spacecraft standardization has been a topic of great debate within the space community. This paper intends to be a provocative thought piece asking one fundamental question: “is there a ‘right size’ for small satellites?” In order to answer this question, we propose three top-down design factors for the space systems engineering process: spacecraft utility, mission utility, and optimum cost. Sp...
متن کاملDeployable Reflectors for Small Satellites
A key limitation for future Small Satellite communications and radar missions will be available antenna reflector aperture. Two types of reflectors are dominant for satellite RF systems today, rigid, single-piece reflectors and deployable mesh reflectors. Single-piece reflectors are limited to the aperture that fits inside a launch vehicle without packaging the reflective surface. Mesh reflecto...
متن کاملPulsed Plasma Thrusters for Small Satellites
Since the Russian launch of the Zond-2 satellite in 1964 there have been over fifty years of research dedicated to the understanding of the first electric propulsion device to be flown in space, the Pulsed Plasma Thruster. The Pulsed Plasma Thruster originates from the evolution of the vacuum arc switch, but due to its microsecond operation time, the internal dynamics and nature of operation ha...
متن کاملInterferometric Missions Using Small Sat Sar Satellites
The Canadian Space Agency (CSA) is currently involved in the development of active membrane antenna technology for SAR applications. To qualify this new technology, it is proposed to develop a small satellite L-band SAR demonstrator. Such a demonstrator could be placed on the same orbit than the ALOS satellite for a tandem interferometric mission. The paper describes the initial science objecti...
