A bit about me

  • Currently with Hydrosat
    • Developing a system to deliver daily, global high-resolution thermal imagery
  • Formerly with Lockheed Martin Space
    • 20 years working in earth-observing “mission planning” / “mission tasking” domains
    • Numerous collection phenomenologies, various missions across all orbit regimes
    • US Government + Commercial missions / use cases

Tasking is: a problem statement

  • To a satellite system, tasking is the dynamic variable
    • Satellite / ground constraints effectively constant
  • Tasking is the external input
    • Describes user needs to scheduler / optimizer
    • Can be optimized and tuned

Satellite schedules

Satellite constraints

Ground constraints

User tasking

Data collection

Collection system bias

  • Basing design on collection systems bring bias
  • Every system has unique drivers
    • Quality: GSD vs GRD vs IPR vs NIIRS
    • Geometry: whole image? center? edges?
    • Time: LEO vs GEO/HEO collectors
    • Repetition:
      • Daily: does 23:59 and 00:05 satisfy 2 days?
      • Separation: measured from start? end? center?
  • Analogy: RCS vs iMessage

Overcome bias: Focus on users

  • Remain focused on user, not satellite
  • Common use cases
    • Geospatial, temporal, geometric constraints
    • Phenomenology extensions
  • Focus on the common user, not the system expert
  • Combine real-world user + satellite system experience to assess impacts and useability, avoid the “ill-defined phase 2”

Perhaps we’re really talking about a Geospatial/temporal data ordering service

Develop standard
