Introduction
1.1 Principle
The Global Acoustic Positioning System GAPS is a portable Ultra Short Base Line (USBL)
with integrated Inertial Navigation System (INS) and Global Navigation Satellite System
(GNSS).
Plug and Play
The GAPS system is recommended for mobile or fixed installations. It can be combined with
an additional hoisting system. It is a plug & play installation. No calibration is required before
using GAPS.
Accuracy
The GAPS system is used to deliver:
●
The position of one or more underwater objects or vehicles, which can maneuver at depth
up to 3,000 meters. Deeper is possible depending on the type of beacon used.
●
The accuracy is up to 0.06 % accuracy of the slant range depending on environmental and
operational conditions.
●
The heading, attitude, motion and position of the support vessel or buoy.
Operation
Principles
The underwater objects or vehicles are tracked using acoustic transponders. The GAPS
antenna is deployed underwater and is usually mounted below the ship hull.
