For what it's worth, the AO-27 web site was providing the same schedule as the
Java program between mid-September (last time the schedule data was
uploaded to the satellite) and the end of October. Early this month,
the 1st, the 6-minute discrepancy between schedules appeared. Other than
the fact the AO-27 onboard clock runs fast (noted on the AO-27 web site), it
appears that the Java program consistently provides the most-accurate
Issues related to the schedule aside, AO-27 still sounds good. It's
been nice to
have this satellite working since January, even with its limitations.
Its passes fit
in nicely between the AO-51 morning and evening passes, with a good turnout
for almost every pass.
