The TX will be ON till the Voltage Controller (UVC) decided to
switch OFF. Now FO-29 is still in eclipses.
For example, if the TX will be switched on at 2100 UTC on Jan 16,
then it will be switched off by UVC at 21:24 UTC due entering
the eclipse. I understand it from the chart below.
Black boxes are the eclipses. Yellow means sunlight (percent of
illumination). You can see that FO-29 is not free of eclipses but
they are getting more and more shorter.
FO-29 is will be switched on after a eclipse and UVC will switch
off if the satellite enters the eclipse (a black box). And you
can see the last eclipse will be on Feb 08 at 00:15 UTC -> after
then we have no eclipses anymore.
You can also use a satellite software like Orbitron to simulate
the orbit and the satellite illumination.
