Sea-eye Underwater starts development of underwater acoustic modemSea-Eye Underwater Ltd. (Ashkelon, Israel) is developing an acoustic modem that it claims could transmit video images in real time wirelessly for underwater communication.

The technology is based on ultrasound and is intended to for the transmission of real-time data, video or sonar images via a modem attached to video cameras or sonar, to be used by both divers and unmanned underwater vehicles (UUVs). The company is aiming to offer wireless real-time communication over a distance of 100 to 200 meters initially and then plans to optimize the technology for communications over 300 to 500 meters.

Sea-Eye Underwater, a startup formed in April 2004, has said it uses frequencies and bandwidths beyond those currently used for underwater and sonar communication, allowing a data transmission rate of up to 200-kbits per second on carrier frequency between 500-KHz and 1-MHz. The company said it has also developed algorithms to cope with underwater noise problems such as multi-path reflection and Doppler effects.

Target markets for the underwater modem are ports and harbor inspection and monitoring, oceanographic surveys, ecological inspection and recording, aqua-culture and fishing, recreational diving, private yacht inspection and homeland security. Sea-Eye Underwater was formed under the framework of the Israeli incubator program of the Office of the Chief Scientist and under the auspices of Ashkelon Technological Industries.
