in the Northern hemisphere.
Hi Alan / Ib
That it is still operational over ZL after half an orbit is very
encouraging. Perhaps we have seen the last of the 'feature' of turning off shortly
after coming out of eclipse. As the team predicted.
At Surrey the team announced the Delfi N3XT project (pronounced 'next').
The satellite will be a 3cube design but with bigger panels and 3 axis
stabilization and a power budget much greater than DO-64. They are looking for ideas
to put on the mission to give some amateur radio functionality in addition to
the science they have planned. V down link and U uplink will be used for
communications. I wonder if 'we' could suggest something in addition to the
obvious transponder. - September deadline for the mission plan. Perhaps the BB
could come up with a list of suggestions.
Perhaps with 3 axis control, a small camera with an image to slowscan
converter would be good. - Then the team can use it to confirm the pointing
accuracy of the satellite and potentially use the GENSO network to issue a 'take
