HAIN: an integrated acoustic positioning and inertial navigation

Exploration on deeper water puts high requirements on underwater positioning for both DP operations and survey applications. Acoustic positioning systems are continuously improved to meet new requirements. Development carried out during the last years for the HUGIN AUV has brought new technology available for combining acoustic positioning with inertial navigation. Based on this the HAIN system is developed as an extension to the HiPAP and HPR systems.
