Data Acquisition Priorities

• 1. Spacecraft Health and Safety
• 2. Data to Assist Emergencies
• 3. Data for Calibration
• 4. Data for Time-Critical Uses
• 5. Data for Non-Time-Critical Uses

5
Operations Planning Availability

• The Mission Management Office (MMO) is open 363
  days a year from 8 AM to 5 PM (Eastern Time)
• On-call support 365 days a year from 6 AM to 10
  PM (Eastern Time)
• Support for Emergencies is available 24 hours a
  day through the International Charter on Space
  and Major Disasters
• Current Timeline
• Shortest possible delay for Routine requests
  is now 29 hours before the satellite executes the
  plan (31 hours for Emergency requests)

Planned Outages

• Spacecraft and Payload maintenance results in
  periods where imaging is not available
• These events are managed to minimize the outage
• OBR Swap, twice a year each for a 5 orbit OBR
  outage (Swapping presently on hold)
• Clock adjustment, once a year for a 30 minute
  outage
• Battery reconditioning, once a year for 30 minute
  outage
• Orbit manoeuvres no longer require a payload
  outage

Special Projects Disaster Watch

• Daily Monitoring of Disaster Occurrences
• Planning of Disaster Acquisitions
• Considered as a mission of opportunity
• Daily Disaster Watch Reports
• Planned acquisitions (restricted distribution)
• Acquired Imagery (public e-mail distribution)
• Disaster Watch Database
• Became operational in mid-1998

24
Special Projects Hurricane Watch

• In collaboration with CCRS, DFO and NOAA
• Airborne and Ground Surveillance (NOAA)
• Planning of Hurricane Acquisitions (Pr. Level 5)
• Hurricane Watch Web site (restricted access)

25
International Charter Space and Major Disaster

• Charter operations are based on a concept of
  joint mission planning operation
• Currently involving CSA, CNES, ESA, ISRO, NOAA
  and CONAE
• Data Acquisition by SAR and Optical sensors
• 24 hours a day World Wide Surveillance

Conclusions

• MMO plays a central role in planning, acquiring,
  archiving, processing and delivering multi-mode
  RADARSAT-1 data to clients globally on an
  operational basis
• As of March 2004, 172,850 user requests
  translating to 323860 minutes of SAR on time have
  been planned
• Average annual system performance close to 96
  has been maintained consistently
• Continue to use satellite and ground system
  resources prudently so as to prolong mission life
• Continue operations transition planning to allow
  a smooth transfer from RADARSAT-1 to RADARSAT-2
