In the framework of the federal target program "Global Positioning System" and the state defense order for 2012 hydrographic survey ships of the Caspian flotilla received two sets of advanced multi-beam echo sounders.
The main purpose of this equipment — inspection of the bottom waters of sea ports, searching underwater objects, measuring the depth from 20 to 11 sq m and maritime safety as the Caspian flotilla of ships and civilian ships.
Advantage multibeam is that for one measurement at a frequency of 1 second are produced
288 depth measurements (by light) on the bottom area of 50 to 200 m2 with an accuracy of 0.5% of the depths. The resulting image is displayed on the bottom topography color display in real time. Standard single-beam echo sounder for the same time allows you to measure the depth of 6-8.
In addition to new sonar on the Caspian Flotilla completed trial operation and put into non-stop operation mode station satellite navigation system GLONASS in its area of responsibility.
This system allows a high degree of accuracy (up to 10 m) and reliability to determine the location of surface ships and commercial vessels.
