Hosted by Nortek
TUE, NOV 17
08:30 - 16:15
National Oceanography Centre (NOC), Southampton
Doppler Dynamics - Navigation
The morning sessions will introduce the fundamentals, ensuring everyone has a shared level of understanding before we explore practical DVL applications and how DVLs can be used most effectively to support subsea navigation.
After lunch, we will head out on the water for a practical demonstration of DVL-aided surface navigation in a GNSS-denied environment, delivered in collaboration with Exail.
There will be regular breaks throughout the day, providing plenty of opportunities to network and speak with Nortek experts. Lunch and refreshments will be provided.
