Motion sensor FT 3D

anemometerheadingposition

Get stable, reliable wind data even in rough conditions. The FT Motion Sensor / Dynamic Monitoring Device fuses IMU and GNSS data to remove vessel motion from apparent wind, with true wind output when heading and speed are valid. Output via NMEA0183 and NMEA 2000.

IMU gives roll, pitch, heave and rate of turn. GNSS gives position, SOG/COG and PPS time. Fusing the two removes vessel or platform motion from apparent wind. The result is a stable, “sanitised” wind output, with true wind available when heading and speed are valid. Sanitised output is delivered as NMEA0183 and NMEA 2000. No need for additional processor to compensate for motion at the masthead wind sensor.

Additional / Optional Features:

• Remote Monitoring

Access the data from your sensors remotely via a web-based platform
View live and historic data from your mobile or PC
Wireless options include WiFi, LoRa, cellular and satellite

• Datalogging

Raw and compensated data logged together with GNSS-synchronised timestamps.
Onboard storage with automatic file rotation and power-fail-safe writes.
Download via internal USB port, or via Wi-Fi once Phase 2 is enabled.

• Comms Translation: Modbus (RS485)

Additional Modbus RTU output alongside the sanitised output.
Register map covers raw wind, compensated wind, roll/pitch/heave, GNSS position and speed, compensation state, logger status and fault flags.
Industry-standard compatibility with PLCs, SCADA and vessel systems.
