Re: PCSAT and mobile satellite OPS

Its easy.  For mid-latitudes, PCsat passes occur in two groups of three
passes.  So if you just happen to  hear the first pass of each three, then
you will hear two more exactly 100 minutes later...  This pattern will
repeat the NEXT day 30 minutes earlier.

After about a week, you will need to ratchet to the next orbit to stay in
sync, so ADD 100 minutes to the pattern once a week...

Right now in the northern hemisphere, PCsat passes are occuring as
follows for the week of 01-31-2002 local sun time:

Sats 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 00 01 02 03
