OpenMCT
- Open-source software dedicated to downlinked telemetry & tracking, health monitoring and sensor data output visualization
- Telemetry pipeline: S/C->ITOS->Warp Server->OpenMCT
- ITOS can be replaced by Ball Aerospace COSMOS (https://cosmosrb.com/), cFS (https://cfs.gsfc.nasa.gov/), Hammers (https://www.hammers.com/products/ground-system-software/galaxy/), YAMCS (https://www.yamcs.org/)
- 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

Tools to investigate are for telemetry & commanding:
- InControl (good functionality and robust; pricey): https://www2.l3t.com/trf/incontrol/index.htm
- ITOS: https://itos.gsfc.nasa.gov/itos-capabilities.php
- ASIST: https://software.nasa.gov/software/GSC-15832-1
- OASIS (should be open to public): http://lasp.colorado.edu/home/mission-ops-data/operational-software/
Recommendations:
- Have at least 2-5 operators working 5 days a week, half-day (ref. LADEE mission)
- Have COTS (PCs, screens etc.) for ground station equipment for operations, go cheap
- Include large screens with clocks, simple setup
- If flying a tech demo, payload, experimental payload on a NASA mission, then the MMOC service will be for free
- Limitation: need to downlink at government-allocated frequencies, not amateur or flexible bands
- Encryption/decryption of science data will delay the distribution of data by at least 1 hr
- Data segmented in downlink to be collected again on ground
- Going through private companies (KSAT) will cost money and delay distribution
- Monitor/tracking of S/C only each pass above Trondheim, otherwise expensive
