The ARB remotely monitors the surfacing of underwater moorings, deep-sea landers, remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs) or other marine platforms operational under water.

If this happens inadvertently the device is an alert instrument similar to the standard SMM (Subsurface Mooring Monitoring Beacon) and one may use the SMM Service of CLS Collecte Localisation Satellites for monitoring the status and the surface position of the "underwater" platform. Compared with the SMM, the ARB is more flexible, smaller, and cheaper in price than a SMM 6000. Use of a three battery power supply produces a medium term transmission time, rather than the long term of the SMM 6000 powered by 10 D-type Lithium cells. However, transmission time reduction is not as great as that for power because a more efficient, lower power PTT is used.

Typical applications are research work in a limited area of a few hundred miles radius and of some weeks duration. On the one hand, instruments can be far enough away for an alert not to be detected by line of sight communications (VHF/UHF radio or optical) and on the other, planned recovery can be thwarted by instrument drift. With location data from the ARB and the CLS service, both aspects are known. With additional equipment of the Marine Recovery Beacon series of products, one has the means to recover one's instruments at any time under any environmental circumstances.
