"Badr-B " internal structure was made of space qualified aluminium eclipse periods.
2.
Mission simulations were performed during thermal vacuum cycling and at the bench using a solar array simulator that was autonomously power toggled with realistic orbital insolation and eclipse periods.
3.
The satellite was put into hibernation for 4 months, until the eclipse period passed, after which systems were turned back on and another 6 months of observations were made.
4.
T Aurigae's period of 4.905 hours, comparable to DQ Herculis's period of 4.65 hours, and has a partial eclipse period of 40 minutes.
5.
The BCDU is a bidirectional power converter that serves a dual function of charging the batteries during solar collection periods ( isolation ) and providing conditioned battery power to the primary power buses during eclipse periods.
