Technical Specifications for Multibeam Echosounder

Minimum requirements for the purchase of the multibeam system are as follows:

1) At a minimum, 160 degrees of swath width. This requirement is needed to optimize data collection efforts in rivers and streams.

2) Selectable frequency range from 200 to 400 kHz. Includes higher frequency option (700 kHz).

3) Minimum of 512 beams.

4) Data acquisition rates above 50 Hz.

5) High accuracy MRU - Applanix POS MV Wavemaster II or comparable.

• Pitch and roll ‐ accuracy within 0.02 degrees.

• Heading ‐ 0.03 degree accuracy.

6) Portability - the system needs to be easily transferable between vessels. The vessels we are currently discussing using the system on are a 14’ John boat and a pontoon boat.

7) Splash proof housings.

8) Industry standard software for data post processing: HyPack, Applanix POSpac - single base.

9) Sound velocity probe.

10) All mounting brackets required must be provided.

11) Complete and in‐depth training of the system.

12) The system must be able to acquire RTK GPS data from in‐house survey system or base station.

13) Must provide backscatter information (snippets).

14) Turnkey system - all necessary components are provided.
