SeaRobotics SR-Surveyor M1.8

Autonomous hydrographic Survey System

The SR-Surveyor M1.8 is a highly capable man-portable
autonomous hydrographic survey vessel. It is tightly integrated
with multiple high-resolution hydrographic sensors
and a topographical mapping LiDAR. It’s unique sensor suite
make it a versatile system for collecting a wide range
of hydrographic data in inland and coastal waters. It’s small
form factor, light weight, and extremely shallow draft allow
it to be rapidly deployed to difficult to access areas.
