As I said in an earlier message, this is an experiment that I want to
run and would rather not touch mission and safety-critical GNC
components, like our navigation GPS receivers. Mass is not an issue.
So I understand that timing is not distributed (or at least not
available to you) in the spacecraft, that's a pity... I've seen in some
spacecrafts that time is distributed using a PPS signal and a
broadcasted message through MIL-1553 bus - would be a lot easier if you
could hang to it (in the cases I know, it was a MIL bus only for the
science payload TCs & HKs - independent from the GNC MIL bus). At least
you're lucky since mass is not an issue (I've met people that would have
killed for and aditional kg)
Regards,
Javier
