Abstract

This paper considers the method of determining the initial orientation of the navigation and measuring complexes of mobile objects. The method is based on analytical gyrocompassing, using angular velocity sensors whose measurements are distorted by additive noise, with a priori uncertain statistical characteristics. The proposed approach requires small computational costs and can be effectively used in the development of high-precision systems of initial orientation of navigation–measurement systems of various mobile objects.

Highlights

One of the promising tendencies of contemporary reforestation is the use of UnmannedMobile Apparatus (UMA) [1] for both ground [2] and aerial seeding [3], as well as for other reforestation operations
One of the most promising ways to solve this problem is the development of algorithms for processing measurements of inertial Sensitive Elements (SE), which are part of the UnmannedMobile Apparatus (UMA)’s navigation–measuring complex, in particular, Angular Velocity Sensors (AVS)

Introduction

One of the promising tendencies of contemporary reforestation is the use of UnmannedMobile Apparatus (UMA) [1] for both ground [2] and aerial seeding [3], as well as for other reforestation operations. The second group of gyrocompassing methods using AVS consists of a reverse change in the AVS sensitivity axis relative to the plane of the local meridian, followed by summation of the measurement signals [11,12]. The problem with these methods is the impossibility of compensation for broadband random noise measurements and low Inventions 2019, 4, 56; doi:10.3390/inventions4040056 www.mdpi.com/journal/inventions accuracy of determining the direction of the local meridian.
