INDUSTRY NEWS
These evaluations confirm the significant improvement in performance of our new heave algorithms, providing superior accuracy and reliability in various conditions.
Conclusion: The performance enhancements are summarized in the table below, showing a clear improvement in both real- time and delayed heave measurements.

Old delayed heave. Mean 4cm, std 2cm
New delayed heave. Mean 1cm, std 2cm
These enhancements ensure that with our high performance product line:
• Real-time heave applications achieve a 4 cm accuracy. • Surveying applications, compatible with delayed heave and supported by major hydrography soſtware packages, achieve a 2 cm accuracy.
Additionally, the heave-enhanced altitude function available on marine units will benefit from these improvements. All these enhancements are available in our Qinertia 4 post-processing soſtware and our high- performance products starting with firmware version 5.1. These improvements will soon extend to our Ellipse product range.
