Mini Satellites Could Revolutionize Space Industry

Posted by ScuttleMonkey on from the smaller-cheaper-space-junk dept.

An anonymous reader writes "Space Daily reports that University of Toronto researchers are working on a project that could replace conventional satellites with a miniature version no larger than a milk carton. From the article: "At only 3.5 kilograms, the Canadian Advanced Nanospace eXperiment 2 (CanX-2) will test small, low-power devices that could lay the groundwork for flying formations of small satellites that could eventually replace larger, more expensive satellites."

    The CanX-2 Mission

    The CanX-2 Mission is the second "NanoSatellite" Mission at the University of Toronto Institute for Aerospace Studies, Space Flight Laboratory (UTIAS/SFL). The Canadian Advanced Nanospace eXperiments (CanX) push the envelope of what can be achieved in space with small, low-power devices. With a focus on aggressive experimentation, CanX missions use the latest commercial technologies and manage moderate risks in exchange for low cost and quick turnaround. UTIAS/SFL is part of an international community of nanosatellite developers that share common launches to reduce costs.

    At 3.5 kilograms and the size of a carton of milk, CanX-2 will be a pathfinder mission in 2006 to evaluate novel technologies that will be used on the CanX-4 / CanX-5 dual satellite mission in 2008 to demonstrate controlled formation flying in space. Formation flying technology will open the door to larger missions for highresolution Earth observation and interferometric imaging that can also be used for space astronomy. The technologies to be tested include a novel propulsion system, custom radios, innovative attitude sensors and actuators, and a commercial GPS receiver.

    In addition to evaluating these miniature technologies, the satellite will also perform experiments for other university researchers across Canada. These include a GPS radio occultation experiment to characterize the upper atmosphere (Calgary), an atmospheric spectrometer to measure greenhouse gases (York), a network communications experiment (Carleton), and a space materials experiments (Toronto).

    Canadian Researchers To Showcase CanX-2 Nanosat August 31

    Toronto ON (SPX) Aug 30, 2005 University of Toronto researchers will demonstrate how a satellite the size of a milk carton that may revolutionize the space industry on Wednesday, Aug. 31, at 10 a.m. at University of Toronto Institute for Aerospace Studies (UTIAS) Lecture Hall, 4925 Dufferin Street.

    At only 3.5 kilograms, the Canadian Advanced Nanospace eXperiment 2 (CanX-2) will test small, low-power devices that could lay the groundwork for flying formations of small satellites that could eventually replace larger, more expensive satellites.

    At the demonstration, researchers will control the CanX-2 nanosatellite through a wireless radio link and download real-time images and telemetry from on-board equipment including a GPS-based positioning system, a miniature propulsion system and tiny devices used for sensing and controlling the satellite's orientation in space.

    "The point of this mission is two-fold," says Professor Robert Zee, managing director of the UTIAS Space Flight Laboratory (SFL).

    "The first is to provide complete development cycle training for students through a real space mission that has to be completed in two years. The second is to launch a tiny research platform into space to test innovative, revolutionary technologies in a rapid, risk-taking manner and also to perform important science missions that are now benefiting from the availability of smaller and smaller instrumentation."

    CanX-2 is the second nanosatellite mission at UTIAS/SFL. CanX-1, Canada's first nanosatellite and one of the smallest satellites ever built, was launched with the MOST microsatellite in 2003 by Eurockot Launch Services from Plesetsk, Russia.

    Sidebar to Second story

     In collaboration with researchers from across Canada, the primary mission of CanX-2 will be a GPS radio occultation experiment to determine vertical profiles of atmospheric properties. It will also perform a number of additional experiments including mobile ad-hoc networking, autonomous control, advanced surface mate
