Multibeam manufacturer WASSP Ltd. announced the release of an independent report on their WMB-3250 Multibeam Sonar.

Based in New Zealand, WASSP Ltd. has been supplying its Multibeam systems globally since 2007 and have over 700 systems being used in the commercial fishing industry and other applications including survey, dredging, fisheries research and defense.

Using advanced signal processing techniques coupled with the latest generation hardware platforms, the WASSP WMB-3250 is a high-quality Multibeam solution that breaks the tradition of a Multibeam system being an expensive and complicated technology to use.

“It was important to us that this report was conducted by an independent party using survey grade equipment with the resulting bathymetric survey data meeting industry standards. We certainly achieved that,” said Terry McDonald, General manager of WASSP Ltd’s parent company Electronic Navigation Ltd.

The report conducted by Durban based company Environmental Mapping & Surveying (EMS) concentrated on a technical evaluation of the WMB3250 performance. Sensors and hydrographic software used included HYPACK, SMC IMU, Valeport SVP and Trimble RTK.

“EMS’s independent technical report clearly shows that the WMB-3250 is able to deliver the results and quality required for most entry level survey/mapping and dredge type applications where cost-effectiveness and ease of use are the prime requirement” McDonald added.

For those readers who require it, analysis of the results verifies its ability to meet IHO Standard 1a.
The report provides a comprehensive review of the systems 'accuracy' across a range of specific performance tests. The 1st component of this report has now been released and is available for downloading from the WASSP website. Additional components will be posted over the next week - these will cover separate and specific performance tests.
