RADARSAT-2 Production
Canadian Data Processing Facility:
• April 2008 – end of commissioning
2008 totals:• ~20 000 scenes processed
2009 totals:• > 50 000 products delivered
• ~75% Electronic Delivery
• Major programs ramping up in 2010 – including NGA, Major Oil Companies and the Canadian DND Polar Epsilon (2 New Ground Stations for rapid ship detection)
Overall System Performance • Completed vs. tasked success rate high (> 97%)• Orbit control improved, with the ground-track now controlled
within +/- 500m• Achieving 0.7 m resolution in azimuth for Spotlight mode
Image Quality• Close to 10% of imagery acquired and processed is used for
calibration
a) Geolocation calibration:• Assessed to be accurate to 10m for finer resolution modes
(Spotlight, UltraFine, Multi-Look Fine, Fine, Fine Quad.) • Assessed accuracy for other modes is better than one
resolution cell
b) Radiometric calibration• Relative radiometric accuracy within a scene <0.5dB• Relative radiometric accuracy between different scenes <1dB

Supports rapid tasking and product delivery • Have already improved ordering timelines
– Now 4 command uplinks per day on regular basis
– Utilizing 2 descending and 2 ascending passes per day over Canada
• Coupled with fast beam switches, ‘store- forward’ capability, rapid processing and automated delivery, RSAT-2 is a incredibly responsive asset34N

Applications: Ice Monitoring• Near-real time wide area monitoring of sea ice and icebergs for
safe vessel navigation in ice-infested waters• RADARSAT has been the primary imaging data source for the
Canadian Ice Service since 1995, replacing the previous method using aircraft surveillance
• RADARSAT is used extensively for ice monitoring by other countries including the U.S., Norway and Denmark
Antarctic Mosaic (RSAT-2)• Continued support to IPY (funded
by CSA)• Data from Oct. - Nov. 2008
– ~1500 Wide 2 (HH+HV) images– ~ 300 Ext High 4 (HH) centre
pole area• 25m ortho+mosaic (to match
original RAMP1 products)
• Near-real time monitoring of ships– Illegal fishing, national security, environmental monitoring and border
monitoring– E.g., Canadian DND – Polar Epsilon
• Wide area monitoring and detection of oil– Detection of oil from both natural (e.g., oil seeps) and anthropogenic
sources (oil spills, illegal dumping) – E.g., EMSA
• Able to perform accurate wide area measurement of winds and waves
Applications: Maritime Surveillance
Strait of Gibraltar, Wide 1 VV Ocean features and ship wakes are visible

SeaView – SAR imagery / AIS Correlation
• Combining multiple sources of Maritime Surveillance data, SeaView offers a powerful, easy to use interface
Detail zoom with metadata available for each probable oil slick detected on the RADARSAT image
SeaView – Delivering Critical Information
Improvements / New Featuresa) Already available:
- Spotlight A (20-49°)- UltraFine covering 20-30°
