The Seapath 200 is designed to meet the precise heading, attitude and position requirements in the latest generation of hydro acoustic positioning and seabed mapping systems. The new generation Seapath includes a range of models: Seapath 100, Seapath 200 and Seapath 200 RTK that suit a large number of applications. The top of the range model, the Seapath 200 RTK (Real Time Kinematic) uses state-of-the-art GPS technology and processing to provide the measurement accuracy that all surveyors have been asking for.

• Centimetre-level position accuracy at several reference points on the vessel
• Real-time tide measurements
• Combined RTK and vertical acceleration heave measurements
• 0.03 in documented roll and pitch dynamic accuracy
• Precise heading and velocity measurements.

The Seapath 200 RTK’s highly accurate roll, pitch and heading measurements allow the RTK antenna position to be referenced to a number of points on the vessel where accurate position and velocity data are required. All the data from Seapath 200 RTK have the same time stamp and the output is in real-time. The high update rate of the IMU data yields output measurements at 100 Hz, including the position data. The Seapath 200 RTK is delivered complete with a Seatex Searef 200 GPS RTK reference station and an UHF radio data link.
