| ACOUSTIC MODEMS |
|
Teledyne Benthos underwater acoustic modems are used in worldwide subsea applications to transmit data wirelessly through the water.
Modem applications include remote monitoring of oceanographic sensors, control of wellhead and pipeline valves, control of autonomous underwater vehicles (AUVs), subsea networking and many military applications. The ATM series acoustic telemetry modems are the most advanced, multi-path and noise tolerant, and cost efficient ever available. They are designed to meet both the high data rate requirements of commercial users, and the higher reliability, lower data rate requirements of the military. "Telesonar" is derived from the words telemetry and sonar, where telemetry is data transmission, and the word sonar (a general term for the applications of underwater sound), was derived many years ago from the acronym for sound navigation and ranging.
