Overview

The F280^® series of GNSS-aided (inertial) attitude and positioning systems are high quality, robust packages for the marine hydrographic and laser survey market.

Defined to meet the exacting requirements of the multibeam survey market, the F280 series systems are easy to install, easy to use and produce very accurate positioning, heading and MOTION data in the most dynamic offshore conditions.

The light yet rugged F280 product series is a reliable and cost-effective solution on marine survey vessels of all sizes.

All systems are dual antenna GPS-, GLONASS- and BeiDou- enabled to improve constellation coverage and heading lock stabilization.

Easy-to-use web interface provides configuration, control and processing functionality including iHeave (intelligent heave).

In addition to real-time heave measurement and output, the F280 series now directly computes and outputs our long-standing and proven iHeave (intelligent Heave) solution without the need for top-side processing or software. iHeave is a tailored solution specifically for long period ocean swell compensation and is fully integrated with the F280 series of Precision Attitude and Positioning Systems. In many parts of the world, hydrographic survey is severely affected by low frequency ocean swells often up to 70 seconds long, resulting in distortions in bathymetric measurements. Conventional techniques for real-time heave measurement can only offer limited accuracy and are insensitive to ocean swells exceeding 10 to 20 seconds. The inbuilt iHeave algorithm analyzes the raw motion data and allows a more accurate determination of the real heave motion experienced by a vessel, and enables the output of precise heave values for all ocean swells.

Additionally, for extremely rapid vessel deployments, a Pre-Calibrated Housing accessory is available to significantly reduce the installation and calibration phases of operation.
