Active Cooling Systems
- Combination of fluid loops and TECs
- TECs are potentially COTS (~$50)
Passive Cooling Systems
Thermal Straps
- Conductively transfer heat
- Doesn't add structural loads
- Blocks at ends of strap to be mounted
Thermal Louvers
- Regulate heat dissipation
- Function as shutters
- Typically associated with larger mass and power input
Deployable Radiators
- Dedicated surface for dissipating excess heat
- Stowed during transit and deployed when needed
MLI/Tapes/Film/Etc.
- Probably not helpful because would interfere with sun radiation (used to stratify temp)
Movement Control
- Use motor encoders to change angle
- Incremental encoder
- Absolute encoder - exact angle
- Magnetic encoder - utilizes small magnet on shaft
