This video demonstrates an OceanAlpha SL40 autonomous survey boat sailing on Loire River in Nantes, France to conduct an autonomous multibeam echosounder survey (June 2019). The 1.6-meter-long SL40 is a unique waterjet hydrographic survey USV. It can carry 15 kg of survey instrument, making it the most economical platform for smaller-sized multibeam echo sounder similar to  R2Sonic 2020 MBES.

The solution scheme and demonstration were carried out by CADDEN Technology Services at R2D3 conference. CADDEN equipped the OceanAlpha SL40 with SBG Systems’ survey-grade yet ultra-compact Ekinox2-D Dual Antenna Inertial Navigation System (INS).
