Precise Positioning With CML Microcircuits' Multi-Mode Two-Way Radio Processors

Standard marine DSC only allows a position resolution down to approximately one nautical mile. In distress situations this is not accurate enough to pin-point a precise position.

The DSC expansion sequences allow precise geographical coordinates to be transmitted, providing position accuracy to less than one metre.

Imagine the situation of a diver in rough seas with strong currents, calling to be picked-up. Providing a 1 square nmi collection position will prolong recovery and potentially put the diver at risk.

A Marine VHF radio with the DSC expansion sequences enabled, would allow the diver to transmit an accurate collection position, down to 1 square metre, ensuring a safe and swift recovery.

The CMX7031 and CMX7041 Multi-mode Two-way Radio Processors are built on FirmASIC component technology allowing on-chip sub-systems to be reconfigured by a Function Image.

These devices enable a revolutionary new platform approach to radio design, enabling multi-mode analogue two-way radios to be developed based on a single radio platform, conforming to many systems: PMR, LMR, Trunking, Marine, Aviation, Amateur radio, NOAA weather radio and packet data radio.
