MTM-203: FAMILY OF MINIATURIZED TRANSCEIVERS
Back to OEM Modules

Product Description
The MTM-203 is a miniature satellite-enhanced L-band transceiver developed based upon messaging and position location system technology that has performed successfully in mobile and airborne platforms used in and around the battlefield. The MTM-203 utilizes state-of-the-art technology created for use where both restrictions in size and weight are critical offering an intelligent resource with clear advantages on the battlefield, homeland and beyond.

Product Overview
The MTM-203 combines compact design and unique functionality to provide integrators with a robust device that can easily be incorporated into other electronic devices including handheld computers, portable battery powered equipment such as laptop and tablet computers plus barcode readers and covert devices. The transceiver's primary function is to allow users and enable applications to send and receive messages via satellite. Additionally, by using the internal GPS receiver, the MTM-203 provides location information on each message and also transmits location information automatically. The MTM-203 is a fundamental system component that soldiers and first responders rely upon when every second does matter and will count!
