Description
The compact and rugged design is based on the field proven WSM mechanics and is available in MF Directional and MF Omni-Directional versions. The latest Sonardyne Wideband®2 signal technology has been incorporated, which offers superior ranging accuracy and fast USBL position updates.
The WSM 6+ improves on its predecessors by offering full two-way Wideband support – interrogation and reply signals. All Wideband V2 and V2+ signals are supported. Legacy support is also available for WBV1 and HPR 400. The configuration is programmable using supplied software and a serial link or it can be configured acoustically via iWand. This allows the WSM 6+ to be configured for use with all of the popular MF frequency acoustic navigation systems.
The Type 8370-1111 WSM 6+ is equipped with an Omni-directional transducer and is depth rated to 1,000 metres making it suitable for a wide range of general USBL tracking applications.
The Type 8370-4112 WSM 6+ is a 4,000 metre rated unit and features a higher power directional transducer.
Both types of WSM 6+ have a depth sensor fitted as standard to aid USBL positioning accuracy and an external on/off switch to save the battery when not in use.
WSM 6+ variants are available with acoustically controlled output lines suitable for external motor drive, burnwire or contact closure releases.
