Seapath 130
Compact GNSS aided inertial navigation system
The Seapath 130 series is developed specifically for hydrographic surveying where high-precision heading, position, velocity, roll, pitch, heave and timing are critical measurements. The product combines state-of-theart multi-frequency GNSS receivers, inertial technology and processing algorithms in a compact and portable package.

Description
High accuracy position output
The advanced Seapath sensor fusion algorithms integrate raw inertial sensor data from our unique and very high-performance MGC® (Motion Gyro Compass), MRU (Motion Reference Unit) or miniMRU, together with raw GNSS data and RTK, PPP or DGNSS corrections. Our unique navigation algorithms enable high accuracy position output even when no correction signals are available.
Inertial sensor
The Seapath is robust against GNSS dropouts by using the inertial sensor for dead reckoning navigation, providing all measurements even when GNSS is not available.
No need for recalibration
The Seapath operator software is installed on the customer’s computer for configuration and monitoring. The latest Seapath software includes Automatic Online Calibration (AOC) which significantly improves the roll and pitch accuracy. With the AOC functionality, a recalibration of the MGC/MRU/miniMRU is no longer required.
