Radarsat 2

 2007-061A

---

The Canadian Space Agency's Radarsat 2 was designed for 3-m resolution radar imaging. The imagery is sold by Radarsat International. The satellite is developed by MDA (MacDonald Dettwiler Associates), a subsidiary of Orbital Sciences which was originally to provide the FUSE medium LeoStar class bus. CSA will own the spacecraft during checkout, but ownership will then pass to MDA Geospatial Services Inc. for operations. In 2007, it was decided that Telesat would operate the satellite.

Orbit will be 798 x 798 km x 98.6 deg. Mass is 2300 kg at launch. Box with 2 panels and 1.5 x 15m SAR antenna. Size is 1.3 x 1.3 x 3.2m, with 15m span.

In Dec 1999 the contract for the bus went to Alenia (to avoid US concerns on radar resolution). Bus is a Prima (Piattaforma Riconfigurabile Italiana Multi-Applicativa) class satellite. Radar is built by Astrium/Portsmouth.

Launch by Soyuz-Fregat in 2007. Soyuz FG No Ts15000-025 and Fregat No 1015-2.
