HAIN Subsea


 
General 
Product Name:HAIN Subsea
Product Description:The HAIN computer receives the aiding positions (latitude and longitude) from an acoustic positioning operator station via an Ethernet interconnection and will limit the position drift that is inherent in inertial navigation systems. ROV position, attitude, speed and expected accuracy of the data are sent to the acoustic positioning operator station, at a 1 Hz update rate. The source of the aiding position can be SSBL, LBL or both.
