New Product Family: Marine Recovery Beacons (MRB)

Surfaced ROVs or AUVs, floating buoys and drifting marine platforms may be found more easily by the research vessel's recovery team when equipped with SiS Marine Recovery Beacons. This family of beacons also helps the finding of deep-sea landers and underwater moorings that may have surfaced inadvertently or have been released acoustically on a specific command. With the Marine Recovery Beacon series of products, one has the means to recover one's instruments at any time under any environmental circumstances.

The new family consists of the following:

Strobe Light Beacon SLB 6000

Flashes by night to show the position of the system
Flash rate, intensity and burst mode adjustable
Range of 4 nautical miles at transmissivity 0.74

GPS Radio Beacon GRB 6000

Takes the system's position from GPS fixes
Transmits these by VHF radio to the search vessel
The receiver on-board the ship is a commercially available PDA

ARGOS Radio Beacon ARB 6000

Allows system's position fixes by the ARGOS system or by a modified receiver of the GRB type
