Laboratory test results underwater navigation system for environmental control devices

Abstract

The work analyzes existing methods for increasing the accuracy of determining weekend navigation parameters of unmanned underwater vehicles. It is proposed to retrofit the navigation system with an additional hydrodynamic tilt unit, which will increase accuracy of coordinate determination. A prototype of the proposed system was made, and algorithmic software for it. Analysis of typical MEMS errors has been completed accelerometers and gyroscopes. To estimate stochastic errors, the Allan variation method was tested using a set of real data obtained on a prototype as input parameters. A model of stochastic errors of all measuring channels has been constructed
