Sub-surface Mooring Monitoring remotely monitors underwater moorings that may accidentally rise to the surface. If the mooring breaks, the platform floats to the surface and starts transmitting.
CLS Service Argos has developed a special service for monitoring the status of the moorings. Normally a submerged Platform Transmitter Terminal (PTT) remains silent and undetected by the Argos satellites.
Should the mooring break loose however, and the PTT rise to within a few metres of the surface, it will begin to transmit. An alarm state is set upon reception of the signal by an orbiting satellite and recognition and processing at a ground centre. A warning that the mooring line has surfaced, with its position, will be sent to the user by facsimile. Thereafter each satellite pass will result in another location. This will continue until cancelled by the user.
High Efficiency True Energy Switch Mode Power Supply
All SMM X series instruments contain an internal switch mode power supply to allow usage of a wide range of battery types. Up to 80% of the batteries initial capacity is used for operation, regardless of cell voltage and current source capabilities.
