A marine motion sensor for vessels that need precise heave, roll, pitch and heading data: dual-antenna 0.05° RMS accuracy across all three axes, heave to 5 cm ± 5%, and a configurable 0.1–100 Hz data update rate — in a 760 g aluminum housing rated IP65 for continuous sea-duty operation.
Highlights
Roll, pitch, heading and heave from a single dual-antenna unit — no separate GNSS receiver or heading sensor wiring.
5 cm ± 5% heave accuracy for multibeam echo sounders, crane monitoring and ride-control systems.
Data rate adjustable from 0.1 to 100 Hz to match sonar, radar or automation polling cycles; RS422/RS232 interfaces.
Applications
Multibeam bathymetry · Vessel ride monitoring · Crane and davit motion compensation · Marine construction

FAQ
What does the V750 measure?
Roll, pitch, heading and heave in one unit — all three attitude axes at ≤0.05° RMS with dual-antenna 2 m baseline input, and heave to 5 cm ± 5% (manufacturer specification).
Which survey instruments pair with it?
The configurable 0.1–100 Hz output and RS422/RS232 interfaces match multibeam echo sounders, motion-referenced cranes and monitoring software polling cycles.
