Satellite phone questions:
The field of satellite communications changes so fast that I feel this question is relevant even if it's been dealt with before. I can't find a recent discussion and I apologize if I simply missed it.
We're in the process of planning a multi-year offshore cruise. This will include the need for good communication to enable our teenage (high school) age kids to communicate with their teachers. As a result of the required robustness of the needed communications, I don't think our winlink (Ham) and sailmail SSB email will be sufficient.
I've been searching for answers but would appreciate opinions. The ability to email and upload as well as download attached files (assignments and marked reports) will be key as will phone calls as required when not able to Skype with shore based Wifi.
I've been reading about the various Inmarsat systems but I'm completely confused by now. Fleet 33? Sailor fleetbroadband 150? 250? Iridium handheld? Goodness, it is so confusing. Any help will be appreciated.
Also, I'd appreciate information regarding cost, from people who have used it.
