A colloid thruster functions by electrostatically generating and accelerating sub-micron droplets of propellant to high velocities. The technology is attractive because of the weight and size of the integrated package, its high efficiency, low power consumption and inert propellant. The development of the thruster prototype at Stanford University is aimed for a proof-of-concept flight-testing o...

CubeSat attitude control systems must be compact, fast, and accurate to achieve success in space missions with stringent control requirements. Nonlinear control strategies allow the creation of robust algorithms for orbit and attitude control, but can have higher processing requirements in operation. In addition, It is desirable to implement distribute components of a CubeSat control system acr...

This article treats the educational aspects of the OUFTI-1 project, whose aim is to build a CubeSat that will carry three payloads. The article addresses the question of maximising hands-on education through such a project. The objectives of the project are presented, and the influence of the first of them (fun and education) on the others objectives is explained. The organization implemented t...

This paper describes the approach taken by the ION-F student team in designing a common Command and Data Handling (C&DH) subsystem for three different nanosatellites. It outlines the requirements of the satellites and reasons behind the decision to develop a custom board. The design is based upon industrial-grade components and centered on a Hitachi SuperH RISC Processor. The C&DH subsystem con...

During the past several years, an interest has g r o w n i n u s i n g c o m m e r c i a l telecommunications techniques to supply Telemetry and Command (T&C) services. An initial study of this concept was performed for NASA in 1996[1]. Recently, the National Aeronautics and Space Administration (NASA) Space Operations Management Office (SOMO) has outlined plans to utilize satellite-based telec...

The Space Flight Laboratory of the University of Toronto Institute for Aerospace Studies has developed a prototype ground station antenna array correlator that offers advantages over previously employed approaches for weak signal communication. By using Orthogonal Frequency Division Multiplexing (OFDM) in the microspacecraft transmission, the array can perform frequency correlation in addition ...

In this paper, we present a system for Distributed Intelligent Planning and Scheduling (DIPS) that helps a spacecraft function as an autonomous agent. A DIPS-based spacecraft receives only high-level goals from ground station operators, and performs its own planning and scheduling onboard, achieving these goals with onboard subsystems and in cooperation with other spacecraft. The task decentral...

Networks of spacecraft are necessary to characterize and constantly monitor near-Earth threats such as Coronal Mass Ejections (CMEs) from the Sun, or impacts by large meteoroids. A network of CubeSat is ideally suited because of the low development cost and for demonstrating continuous monitoring of rare phenomena. In this paper, we describe the ongoing development of a single prototype spacecr...

Abstract OPS-SAT is an ESA nanosatellite launched in December 2019. The spacecraft open for third-party experiments, which can use almost all functions provided by the and take full control of it. Depending on experiment usage payload, power consumption may be as small a few watts but exceed 30 W at load. peak production lies same order magnitude, highly demanding thermal regulation. This artic...
