  • Open-source software dedicated to downlinked telemetry & tracking, health monitoring and sensor data output visualization
  • Telemetry pipeline: S/C->ITOS->Warp Server->OpenMCT
  • MARCO mission (https://www.jpl.nasa.gov/cubesat/missions/marco.php) currently uses OpenMCT for:
    • Monitoring solar panel deployment and energy harvesting
    • Detumbling + orbit insertion monitoring
    • Works a situational awareness tool
    • They have their own command & control plug-in that works for the uplink part
  • May be found on https://nasa.github.io/openmct/
    • A couple of functionalities need to be requested such as e.g. 
  • Receives a BSON message format, in csv. file.
    • Need time-stamps
  • WorldWind (https://worldwind.arc.nasa.gov/) for visualization + orbit propagation based on Two-Line-Elements (TLE)
  • Some missions flying with OpenMCT for monitoring:
    • Jason-3
    • MARCO
    • ICESat-2
  • How to deploy OpenMCT server: Deploying Open MCT Server.pdf
  • They recommend monitoring/tracking the S/C in every orbit, not only every pass (8) above Trondheim
  • Open to work with us on development (orbit propagation, VV of S/C maneuvers, command & uplink etc.)
  • Multi-mission operations at different locations (think Trondheim, Svalbard, Porto, NASA Ames) at the same time

Bresina & Morris

Bresina and Morris worked with Kanna on the MER mission for MAPGEN. Slides on MAPGEN functional view are at: https://www.dropbox.com/s/3mwkok8nnlvbq23/MAPGEN-MER.pdf?dl=0

  • MAPGEN as a model for HYPSO is important, since we will be using the 'mixed-initiative' (human-in-the-loop) control methodology. See GDS slides at: <GDS slides on this Wiki> to show the recommended evolution 
  • Fundamentally there is a front end visualization framework (JPL's APGEN software) and the back end AI Planner
  • We cannot use MAPGEN since it is export controlled and old now
  • Open-Spify is the "new" MAPGEN with caveats
    • It can come with and with a new Java front-end + constraint engine + planner (optional)
    • The constraint engine does local propagation to detect planning/scheduling conflicts but does not resolve the conflicts. With a planner, the resolution occurs aided by a model with heuristics to minimize search. 
    • There can be two types of planning engines (both EUROPA based https://github.com/nasa/europa/wiki/Europa-Background)
    • Batch and dynamic – typically batch processing implies a set of goals are fed into the planner, when the crank is turned the planner generates a possible plan, as an outcome (assuming a plan is viable). This was what MAPGEN was doing on MER.
    • A dynamic planner will continuously modify an output plan while interacting with the front end and/or other sources of information.
    • For HYPSO, we will rely on the simpler form of (static or batch) planning and push to look towards how to formulate resource constrained plans.
    • This will ensure, we are building something useful operationally for HYPSO, and then build some novel resource optimization work on top ideal for a PhD dissertation.
  • More info on Spify being collated.
