Orbcomm is kind of troublesome. There is a tracking service used mostly by helicopters, which of course are notorious for falling off the radar due to low altitude. It is Iridium based. > http://us.spidertracks.com/ I've used or have know users various satellite messaging services over the years. Iridium is good. I was a Globcomm customer, but it was not reliable. A friend was on Orbcomm and it had issues as well. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
