decimetre positioning accuracy.

 

an automatic pilot which controls a vessel's engines and rudder, generally to ensure the vessel maintains station. Such systems require input from an accurate positioning system as a reference.

electromagnetic measurements used to measure sub-surface electrical conductivity as a tool to map geological conditions and changes for engineering and exploration use.

a system that, with the help of a laser fan beam in a helicopter, generates accurate relief maps.

Geographic Information System. Glonass:

 

acoustic measuring technology which uses single vessel-towed hydrophone streamers. This technique generates a 2D cross-section of the deep seabed and is used primarily when initially reconnoitring for the presence of oil or gas reservoirs.

accoustic measuring technology which uses multiple vessel-towed long hydrophone streamers. This technique generates a 3D model of the deep seabed and is used to locate and analyse oil and gas reservoirs. 3 DiQ (3D Integrated Quantitative):

a management system that ensures the efficient use of business equipment such as vessels, measuring equipment, etc. Asset monitoring:
