Action items
Data from HSI
- Sivert is working on his project.
- HICO-data is level 1B, they might have level 1a - but most likely not level 0
- Ocean Virtual Laboratory might have level 1a becuase you can go back to level 0 and up to level 1b
- Joao:
- Evelyn and Joao had a chat last week
- Operational data (time-sensitive) vs. scientific data (not as time-sensitive)
- If we do a scan, and do some processing (might even be lossy) - and downlink it quickly so that the UAV/USV may go explore. The operational data needs to be good enough to make a decision. Actionable data.
- But the not time-sensitive lossless scientific raw data is downlinked in later orbits (level 1a or level 0)
- Do we have enough memory to choose which raw data from orbits within a timespan do downlink?
- Video compression techniques - write a journal paper! Change time to wavelength
- Fresh water algae bloom?
- Find scientists and fly a drone with them
- Geir Johnsen
Hardware
- PCBs into production next week
- Documentation:
- Confluence for now
- Fred says that we can copy it for internal use
Software
- Power estimation:
- ARM-processing system + core. Still working on it to provide estimation with the Xilinq tool
- There will be a meeting later today
Mission Design
- 10AM-orbit: Cover Trondheim. Inclination RAAN of 83 degrees - sun-synchronous orbit
- Worst-case
- 10 phases
- Power budget shows that it is difficult to downlink data all orbits
- Sun is always behind you
- 10PM-orbit: Cover the whole coast of Norway.
- Not easy to find launchers
- Power 3U
- Maximum solar power: TBD - we assume 10W?
- Battery: 2600mAh
- Difficult to find the actual power provided by the solar panels
- We do not want a mid-day orbit
Communication
- Gara has updated the link budget using different assumptions/ground stations - see gdrive
- Missing noise figures+++
- Preliminary budget: good enough
