steps of TCS
Check the temperature requirements of subsystems
Storage
operating
Get the external heat environment from the determined attitude and the orbit
Get the internal heat condition from the datasheet of subsystems and the desired operating time
Determine TCS
Where need thermal control?
To heat or to cool down?
What will you use to control and to monitor?
The requriements for STR and TCS
To survive the whole launch, and combine subsystems together
To prevent subsystems from heat death or dead in cold condition through its whole life
To separate two distinct satellites
To easily construct and maintain the S/C
