Iridium-based email at sea

Another piece from BYM News finds yet another shipping company to equip its ships with a crew email system based on using the Iridium satellite system as a transport method. Zodiac Maritime Agencies Ltd. installed Thrane&Thrane Sailor ST4120 trasnceivers on its 132 ships, allowing crew members to have personal mailboxes and send/receive on a prepaid basis.

Given the Iridium data transfer speeds of just 2.4 Kbps, emailing must be restricted to text only messages, as a 500 kilobyte picture would take about 30 minutes to send or receive over the Iridium network.
