Purplefinder LRIT

The Purplefinder LRIT by Pole Star is a combined Long Range Identification & Tracking (LRIT) and Ship Security Alert System (SSAS) unit, providing mandatory global vessel identification via satellite in a single integrated package. The supplied category identifies the equipment as LRIT (Long Range Identification & Tracking), and it is normally installed on the bridge or within the vessel security and recording network with cameras, sensors, displays or data-storage interfaces. In that listed role, its primary purpose is to record voyage data, monitor bridge activity, supervise watchkeeping or support vessel security according to the listed function. VDR, BNWAS, CCTV, access-control, SSAS and LRIT systems have different statutory roles, so alarms, data retention and communication paths must be checked against the actual installation. The model designation identifies the listed configuration, but no additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. The source metadata also states capacity: Satellite LRIT. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
