The SHOUT tw is an IP67-rated handheld, global, two-way satellite messaging and personal tracking device. It utilizes Iridium’s short burst data (SBD) service to provide location information determined by a GPS receiver, two-way inbound and outbound status, text messaging, and emergency/alert notifications.
The SHOUT tw is designed with ultra-low power consumption electronics drawing less than 35A 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 1,600 reports). The SHOUT tw is equipped with a resistive high-resolution color touchscreen supporting transmission of free-text, canned messages, and a combination of free-text and canned messages. Similar to a “smart” phone, the menu options are displayed as icons for quick access. The device can periodically wake up from sleep to send its position report to a command center. A 911 button is used for immediate emergency/alert notifications. Data is packaged in either standard or 256-bit AES encrypted format. Data can also be sent in encrypted PECOS formats to include Brevity codes.
