ABSTRACT: Aricopter is a COTS micro-helicopter heavily modified for research on embedded flight and vision controls, and distributed autonomy. In this work, we present an overview of the exciting development process of the flight hardware, the micro-avionics system, and the off-board vision implementations.

ABSTRACT: Distributed spacecraft systems is envisioned to provide the technology platform to extend, improve and enable mission concepts such as wide aperture radars for high-precision space-borne surveillance, 3D mapping of Earth's magnetic field and even deep-space interferometry to better understand the origins of the universe. However, a mission with a fully autonomous spacecraft fleet flying in close-proximity or in a tightly kept configuration has yet to be realized. In this work, we review the major technology drivers and challenges for such next generation systems across a selective set of on-going, cancelled or proposed space missions. Our analyses identify five main classes of technology drivers from navigation and control perspective. These drivers are enumerated for a typical interferometric SAR example. The example illustrates steep technological challenges such as the need for sub-millimeter relative navigation solution accuracy for even decimeter level vertical image resolution. We conclude with an initial effort at outlining a cost effective and robust roadmap for flight maturation of the key technologies to deem such missions and goals achievable.

ABSTRACT: ITU-pSAT I is the first student designed pico-satellite of Turkey to be launched in 2008 as a part of the international CubeSat program. It carries two experimental payloads; a low-resolution camera with onboard image pre-processing, and passive magnetic stabilization with a magnetic rod accompanied by a sensor board to examine its performance. The design philosophy of pSAT I aims for a reliable and simple bus that is also expandable. In this work, we give an overview of the on-going Engineering Model development, provide insight to the satellite's subsystems and introduce the established Space Systems Development and Testing Laboratory.
