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)

7
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

On-Board Recorder
  • Current OBR Operational Baseline
  • 1 playbacks per day on average
  • Playbacks at GSS and PASS (ASF used
    exceptionally)
  • Current constraint
  • Average of 72 on/offs per day
  • Total lifetime of 136,000 on/offs per OBR
  • Current use
  • Average use of 24 on/offs per day
  • 47,260 used to date (including both OBRs)
  • Current problem
  • OBR2 not operational. Under investigation for its
    anomalous behavior

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
