“…The IMU contains three single-axis accelerometers and three single-axis gyroscopes. The accelerometer detects the acceleration signal of the object in the vector's three-axis independent coordinate system, while the gyroscope detects the vector's angular velocity signal relative to the navigation coordinate system to measure the object's angular velocity and acceleration in three-dimensional space and use that to calculate the body's position [13]. It has a very important application value in navigation.…”

In recent years, there has been a significant increase in the use of location-based solutions. As a result, data encryption has become increasingly important in order to ensure privacy and confidentiality, especially in all domains, military and civil alike. This paper presents an application that will be used in both military and civilian situations, encrypting data on the location and movements of military personnel or civilian prospectors within a specific area using transmitting and receiving circuits controlled by a microcontroller programmed with the proposed encryption algorithm. The application will be used in both military and civilian settings. Depending on the task at hand or the nature of the immediate surroundings, the proposed application has been introduced, installed, and used in a variety of ways. The proposed technology has been tested in a variety of situations and has produced excellent results in all of them. The suggested application is confidential, authenticated, and simple to use, according to the results of frequency, speed, and security testing; this has been demonstrated by the results of these tests.

A redundant rotational inertial navigation system (RRINS) comprises a redundant inertial measurement unit (RIMU) and a turntable for improving reliability and navigation accuracy. Because of the multi-sensor configuration, the RIMU has a more complex error model compared with the traditional orthogonal inertial measurement unit (IMU). Therefore, the RIMU-based rotation scheme cannot simply replicate the traditional IMU-based rotation scheme. In this study, a dual-axis rotation scheme for RIMU characteristics is proposed. First, the error model of the RIMU was established, and the error compensation of RIMU caused by rotation was analyzed. Second, the principles of rotation axis switching and reciprocating rotation were summarized, and a dual-axis rotation scheme was designed by these principles. Finally, the rotation scheme was applied to an RRINS prototype consisting of RIMU (four fiber optic gyroscopes + four quartz accelerometers) and a dual-axis turntable, and then simulations and experiments were performed. The results of the simulations and experiments show that the positioning accuracy of RRINS can be obviously improved by using the proposed rotation scheme.

“…The aircraft control systems of various classes and purposes, including unmanned aerial vehicles and small spacecrafts, must meet the requirements toward ensuring reliability and operability in the case of possible failures. One of the ways to increase reliability and ensure fault tolerance has traditionally been the use of information redundancy [1][2][3][4][5].…”

This paper aims to assess the possibility of using functionally redundant inertial units to solve problems of increasing reliability and ensuring the fault tolerance of the various classes and purposes of aircraft navigation systems. We present the results of studying failure detection methods to improve the accuracy and reliability of a strapdown functionally redundant inertial unit. The resulting structural redundancy of the strapdown inertial measurement unit is designed to increase the fault tolerance and accuracy of strapdown inertial navigation systems. The methods for detecting sensor failures in functionally redundant inertial units are based on the use of the equations of functionally redundant inertial unit compliance to nominal requirements for the accuracy of measuring the input action vector. To describe the methods for detecting and eliminating failed sensor and algorithm designs based on them, we gave the mathematical models of the measurement vector of functionally redundant inertial units concerning the measured vector and the error identification condition, including the residual of the matching equations with the size due to the level of redundancy, determining the total number of matching equations. The main criterion for determining a failed sensor is non-compliance with the nominal value of the residual included in a certain number of matching equations of the information received from such meters. The developed algorithms are examined using simulation methods. The study of the selected structure of the functionally redundant inertial units shows that the proposed approaches are efficient. Also, we manage to identify the main characteristics of the algorithms for detecting sensor failures that are structurally a part of the functionally redundant inertial units.
