We executed heat test for Cute-1.7 + APD II in 21,22/Dec/2006 using thermostatic chamber.
Objective of thermal test
The orbit of Cute-1.7 + APD II is the sun synchronous orbit which height is 630km and local time of ascending node is 10:30 am. So in one pass, there are 60 minutes sunlight time and 30 minutes umbra time. Therefore the temperature of satellite change from low to high. We have to certificate that our satellite system is able to operate under such temperature.
