Study of the possibility of using strapdown inertial gauges as part of the topographic location and navigation system of own design

Abstract

Problem statement. During the operation of purchased navigation systems for topographic geodetic referencing and orientation, many shortcomings are revealed, mainly associated with software implementation, the correction of which is not always possible. A way out of this situation is creating own navigation complex from ready-made purchased meters and developed functional software (FSW). In this case, the primary task is to determine the preferable meters as part of the topographic location and navigation system (TLNS).Objective. Conduct a study of strapdown inertial navigation systems (SINS) of various manufacturers for compliance with the declared technical characteristics to determine a suitable meter for TLNS.Results. Information on the practical testing of studies the numerical estimates of standard deviations (SD) of errors in the determination and drift of grid azimuth, roll, and pitch of strapdown inertial meters in various climatic conditions, as well as under the influence of sinusoidal and broadband random vibrations (BRV) is presented. The values deviations of motion parameters from the reference values in autonomous mode as part of the developed navigation complex of mobile land objects of a particular purpose are analyzed. The preferable inertial meter for use in the developed TLNS was determined based on the research carried out.Practical implications. Recommendations are given on the use of SINS as an integral part at the facilities of the proposed base.
