RADARSAT-1 used a synthetic aperture radar (SAR) sensor to image the Earth at a single microwave frequency of 5.3 GHz, in the C band (wavelength of 5.6 cm). [1] The SAR support structure was designed and manufactured by Northrop Grumman Astro Aerospace and deployed to 15 m (49 ft) in length on orbit.
RADARSAT-2 was constructed with several improvements over the RADARSAT-1 project, making it one of the most advanced radar imaging satellites in the world. [4] Some of the improvements over RADARSAT-1 include increased spatial resolution, multiple polarization filters, solid state recorders, and GPS receivers on board.
MDA was primary contractor for, and took ownership of, the RADARSAT-2 Earth observation satellite. [4] MDA bought the space robotics division of Spar Aerospace—manufacturer of the Canadarm—in March 1999, renaming it MD Robotics. The company completed the Mobile Servicing System (including the Canadarm2) for the International Space Station. [5]
The RADARSAT Constellation Mission (RCM) is a three-spacecraft fleet of Earth observation satellites operated by the Canadian Space Agency.The RCM's goal is to provide data for climate research and commercial applications including oil exploration, fishing, shipping, etc. [3] With satellites smaller than RADARSAT-2, [4] the RCM will provide new applications—made possible through the ...
RADARSAT-2 is a Canadian Space Agency (CSA) Earth observation satellite. It launched on 14 December 2007 aboard a Starsem Soyuz-FG rocket from Baikonur Cosmodrome , Kazakhstan . [ 1 ] The spacecraft is owned by MDA (formerly MacDonald Dettwiler and Associates.) [ 2 ]
The Near Earth Object Surveillance Satellite (NEOSSat) [8] is a Canadian microsatellite using a 15-cm aperture f/5.88 Maksutov telescope (similar to that on the MOST spacecraft), with 3-axis stabilisation giving a pointing stability of ~2 arcseconds in a ~100 second exposure.
EV1 works with satellite vendors from France [1] (Spot 6 & 7, Pléiades 1A & 1B), Canada (RADARSAT 1 & 2), and India (CARTOSAT1 & 2) to provide unclassified imagery to customers. EV1 is part of a larger Eagle Vision enterprise that consists of four other units stationed in South Carolina, Alabama, California, and Hawaii.
ERS-1 had various mission phases using 3-day and 35-day repeat cycles. During the geodetic mission, ERS-1 was put in two long repeat cycles of 168 days, which is equivalent to a single 336-day cycle. The geodetic mission allowed for accurate mapping of the Earth's bathymetry and geoid over the seas using the Radar Altimeter.
