The Iridium Shout TS is the same as the Iridium Shout Nano but with a touchscreen allowing quick access to menus and ease of entering text via on-screen keyboards. Similar to the Nano, the TS is designed with ultra-low power consumption electronics drawing less than 35µA during sleep.
With an internal 1.95 A-Hr rechargeable Li-Ion battery, it can send a position report every hour for up to two months (about 1,500 reports). The device can periodically wake up from sleep to send its position report to a command centre. A guarded 911 button is used for immediate emergency/alert notifications. Data are packaged in either standard or 256-bit AES encrypted 10-byte, 30-byte or PECOS format.
