EM 710 Multibeam echosounder
EM 710 Multibeam echosounder models
There are three basic versions of the EM 710 multibeam echosounder each with different range performances:
- EM 710 - Full performance version
- EM 710S - CW pulse forms only
- EM 710RD - Short CW pulse only
Alternative post processing software
- CARIS HIPS/SIPS post processing
- Cfloor integrated with Neptune for digital terrain modelling
- Fledermaus interactive 3D visualisation
Note: KONGSBERG is not responsible for any system malfunction caused by 3rd party software.
Defining a new resolution standard for bathymetric surveys
One of the goals when we developed the EM 710 0.5x1 multibeam echo sounder system was to offer to the market a higher standard of resolution than previously possible. The improved resolution is provided by the 0.5 degree, focussed transmit beam - in combination with high density processing applied to the high number of dynamically focussed receive beams. The 0.5 degree transmit beam has a very small footprint, only 85cm long at 100m depth. So in order to ensure 100% bottom coverage even at high survey speeds we developed a new scheme by which 2 complete sounding profiles are generated for each ping cycle.
So at 100m depth, with full swath width +/-70 degrees the system has 2 pings per second, or 4 sounding profiles. The maximum survey speed while maintaining 100% bottom coverage is then 3.4 m/sec or 6.8 knots. By reducing the swath width to +/- 55 degrees, the ping rate is increased to 3.4 and the survey speed can then be raised to 11.5 knots. Each sounding profile consists of 400 soundings.
