  • Radarsat Range Adjustment Mechanism Design
    Radarsat Range Adjustment Mechanism Design Xilin Zhang* and Sylvain Riendeau* Abstract RADARSAT (Figure 1) is a series of sophisticated earth observation satellites developed by Canada to monitor environmental changes and the planet’s natural resources. RADARSAT also provides useful information to both commercial and scientific users in the fields of agriculture, cartography, hydrology, forestry, oceanography, ice studies, and coastal monitoring. At the heart of each RADARSAT satellite, there is an advanced Synthetic Aperture Radar (SAR) payload. The SAR antenna is a 15-meter-long microwave instrument that sends pulsed signals to Earth and processes the received reflected pulses. Its on-ground test fixture has high-resolution alignment requirements. It is a challenge to any mechanical designer. The Radarsat-1 test fixture included an 18- meter-long near field range scanner, an offloaded 6 degrees-of-freedom fine adjustment system to handle and maneuver the 15-meter-long SAR antenna, an automatic closed-loop motor-driven adjustment system, and a 15-meter-long coarse adjustment table. A large R & D effort was required throughout the design, fabrication and final calibration of the equipment to ensure final success. Lessons learned from the RADARSAT-1 range alignment fixture paved the road for the RADARSAT-2 system. This type of 6 degrees-of-freedom adjustment mechanism could be very useful to all kinds of large space structures for on-ground alignment and test like solar arrays, antenna panels, etc. This paper covers the 6 degrees-of- freedom mechanism design, development, fabrication and off loading calibration method. The lessons learned during design, fabrication as well as integration and calibration are extremely useful to avoid future problems for all mechanism designers.

  • Magellan Aerospace-Built Mac-200 Bus Celebrates One-Year in Space on Cassiope Mission
    FOR IMMEDIATE RELEASE VIA THE CANADIAN CUSTOM DISCLOSURE NETWORK MAGELLAN AEROSPACE-BUILT MAC-200 BUS CELEBRATES ONE-YEAR IN SPACE ON CASSIOPE MISSION Toronto, Ontario – October 3, 2014 – Magellan Aerospace is proud to celebrate the first anniversary of its MAC-200 Bus on the Cascade SmallSat and IOnospheric Polar Explorer (CASSIOPE) mission in space. The mission has been developed and implemented by Canadian industry led by MacDonald, Dettwiler and Associates Ltd. (MDA), as prime contractor, with important contributions from the Canadian industry team, which includes Magellan Aerospace. The mission launched on 29 September 2013, carrying eight science instruments, collectively named e-Pop (Enhanced Polar Outflow Probe) as well as a second payload for advanced telecommunications technology demonstration (termed Cascade). The two payloads were assembled into Magellan’s MAC-200 satellite bus and have been operating in space for one year. Mr. James S. Butyniec, CEO of Magellan Aerospace said, “The anniversary of the CASSIOPE is a great accomplishment that we celebrate with the Canadian Space Agency, MacDonald, Dettwiler and Associates Ltd. (MDA), and all of the Canadian industrial contributors and scientists who contribute to advancing Canada’s space technology capabilities. Congratulations also to the Institute of Space Imaging at the University of Calgary, the user and mission operator of the e-Pop payload. For the last year e-Pop has been collecting data on space storms and their potential impacts on radio communications, GPS navigation, and other space-based technologies.” He continued, “Magellan is very proud of the accomplishments of the team in our space business who contributed to establishing a world-class Centre of Excellence for Rockets and Space, including the design and development of satellite buses, and assembly, integration and test.” The CASSIOPE satellite bus was designed and built in Magellan Aerospace, Winnipeg.

  • THE GPS ATTITUDE, POSITIONING, and PROFILING EXPERIMENT for the ENHANCED POLAR OUTFLOW PROBE PLATFORM on the CANADIAN CASSIOPE SATELLITE Don Kim and Richard B
    G E O M A T I C A THE GPS ATTITUDE, POSITIONING, AND PROFILING EXPERIMENT FOR THE ENHANCED POLAR OUTFLOW PROBE PLATFORM ON THE CANADIAN CASSIOPE SATELLITE Don Kim and Richard B. Langley Department of Geodesy and Geomatics Engineering, University of New Brunswick The CAScade, Smallsat and IOnospheric Polar Explorer, or CASSIOPE, is Canada’s first multi-purpose small satellite, scheduled to be launched in 2011. It features two main payloads: the Enhanced Polar Outflow Probe, or e-POP, and Cascade. Together, they will achieve both a scientific and a commercial objective: e-POP will provide scientists with unprecedented details about the Earth’s ionosphere, thermosphere, and magne- tosphere, helping scientists better understand the cause and effects of potentially dangerous space weather, while Cascade will demonstrate a new high-capacity store-and-forward digital communications service. e-POP consists of eight scientific instruments, one of which is the GPS Attitude, Positioning, and Profiling experiment (GAP). GAP employs five dual-frequency GPS (Global Positioning System) receivers and associ- ated antennas to provide the e-POP payload with high-resolution spatial positioning information, flight-path velocity determination, and real-time, high-stability timing. In addition, by measuring the arrival times of the Don Kim GPS signal wave fronts at each antenna against a very stable time base, the relative range between antennas kim@unb.ca can be determined, yielding real-time spacecraft attitude determination. The GAP receivers are slightly modified, commercial, off-the-shelf units that required a series of tests before they could be considered capa- ble for use on an orbiting spacecraft.

Activities organized throughout the year to commemorate the occasion culminated in a meeting of global space industry leaders at the International Astronautical Congress in Vancouver, Canada, in October. Canadian Space Agency (CSA) President Marc Garneau, and ESA Director General Jean-Jacques Dordain highlighted technological, scientific, and industrial discovery, exploration, and applications—the results of cooperation that has, for a quarter century, delivered far-reaching social and economic benefits to humanity. A brochure on the 25 years of cooperation can be found on CSA's website at http://www.space.gc.ca/asc/pdf/canada-esa-25e.pdf. 2. October 2004 marked the 20th anniversary of Canada's Human Presence in Space. Canadians watched with pride on 5 October 1984, as Marc Garneau became the first Canadian to travel to space.

  • MARC GARNEAU by Pat Carney March 14, 2013 I Am a Card Carrying
    MARC GARNEAU By Pat Carney March 14, 2013 I am a card carrying Conservative. I do not plan to vote Liberal in the next election. But as a Canadian, I regret that by withdrawing from the Liberal leadership race Canada’s first astronaut, MP Marc Garneau has denied Canadians the opportunity to experience the initiative and insight he demonstrated in the mid 1980’s, when I was the federal minister in charge of Canada’s fledging space program. As Minister for Energy Mines and Resources in Brian Mulroney’s government I was responsible for a range of innovative space programs then on the drawing boards. This was an enthralling assignment, since before I was elected to Parliament I was involved in tele-education and tele-medicine experiments on Canada’s Hermes satellite, the world’s first geostationary interactive communications satellite, and later on other Canadian communication satellite projects. Canada was a world leader in the field. But when Prime Minister Mulroney accepted President Ronald Reagan’s invitation for Canadian participation in the American international space station in 1985, Canada’s own space programs fell under the budget cutting axe to free up the funds. My officials and I were determined to save at least one of our own Canadian programs, But which one? Each had its own competing interests and potential customers. In January 1986 the American space shuttle Challenger exploded seconds after take-off, killing all seven crew members. Astronaut Marc Garneau and I were assigned by the PM to represent Canada at the memorial service for the crew at Cape Canaveral.
