DRX INSTALLATION MANUAL
DRX INSTALLATION MANUAL
1.1. MAIN FEATURES
The main features of DRX in a multibeam configuration will depend on the model as
follows:
»
Variable number of beams - Model and configuration dependent.
»
120° Swath coverage – Transducer dependent.
»
Depth capability is configuration and environment dependent. Typical
configurations:
• DRX-25 with WMB160 transducer; 1 to 150m
• DRX-32 with WMB160 transducer; 1 to 200m
• DRX-46 with WMB160 transducer; 1 to 400m
• DRX-46 with WMB80 transducer; 2 to 600m
»
Variable frequencies.
»
Supported by multiple client applications to meet different customer requirements.
»
Direct Ethernet connection to multiple client applications.
»
Continuous real-time 2D and 3D mapping.
»
Easy to operate and quick to install.
»
Web based setup and configuration.
»
Beam stabilisation.
»
Variable beam width.
2 SYSTEM OVERVIEW
The WASSP multibeam sounder system requires the following components:
DRX;
Transmit, receive, digital signal processing, display processing, License management
and data server for client applications.
WASSP TRANSDUCER;
See WASSP Transducer Reference Manual.
PC;
Control, post processing and viewing of sounder, sonar and mapping needs to be
handled by a suitable application, running on PC or tablet.
GPS;
Position and time required for water column and bathymetry geo-referencing.
HEADING SENSOR;
Required for correctly orienting the multibeam data.
MOTION SENSOR;
Required for stabilising the water column and bathymetry data for
vessel roll, pitch and heave.
SOUND VELOCITY PROBE;
Required for correcting Sound Velocity in order to improve
depth accuracy across the swath.
SOUND VELOCITY PROFILER;
For accurate range measurement, sound velocity needs
to be known at the transducer and through the water column. The Sound Velocity Profile
information can be applied if using 3rd Party applications supporting SVP.
NOTE: As with any multibeam sounder, the quality of the sensors connected
will directly affect the performance of the system. Enhancements to system
performance include using high precision RTK GPS, accurate sound velocity
measurements, sound velocity profiles, and high performance motion sensors.
Your WASSP dealer can advise on sensors to suit your requirements. WASSP
recommended sensors are also detailed in this manual,
Supported Sensors and Sentences” on page 87.
The WASSP system can be supplied in various configurations to allow customised or
turnkey solutions. These include:
»
DRX and transducer with WASSP CDX and sensor package; Customer supplies PC or
tablet and optionally 3rd Party navigation, fishing or survey package.
»
DRX and transducer with WASSP CDX; Customer supplies sensors, PC or tablet and
optionally 3rd Party navigation, fishing or survey package.
»
DRX and transducer with WASSP CDX and sensor package and wireless package;
Customer supplies PC or tablet.
For details on WASSP system packages available see
NOTE: Sensor package details can be found in the WASSP Sensor Box
