In recent years, Micro Aerial Vehicles (MAVs) have been a desired solution for indoor applications. However, most of today's approaches are restricted to piloted applications for lack of autonomy in unknown scenario. There, the MAV must independently handle both infrastructure and arbitrary obstacles. We present a navigation system for autonomous flight in cluttered indoor environments. First, we transfer the Elliptic Limit Cycle (ELC) approach for target-oriented obstacle avoidance to the dynamics of MAV flights. In terms of automated perceptive functionality, laser data clustering and parameter estimation on the fly are presented. Second, we develop refinements to simultaneously handle both isolated obstacles and connected infrastructure, which is a necessary condition for any indoor application. We evaluate the automated obstacle perception by means of real experimental data acquired in interior space. The guidance system's proof of concept is given based on realistic indoor environment software in the loop tests.

This paper is devoted to the problem of increasing the accuracy of measuring of flight paths of aircraft using optoelectronic systems (OES) in sea conditions. In such conditions, it is necessary to determine and compensate for the trajectory instabilities caused by the swinging base of the OES. It is proposed to determine and compensate for these instabilities using an inertial-satellite navigation system. The problems arising from this and their solutions are considered. The results of seminatural studies are presented.

The paper presents a novel calibration method for gyroscopes and accelerometers. Contrary to existing methods the proposed one does not require a rotating table or other special equipment. To perform the calibration a user needs to make a series of sequential rotations of inertial measurement unit (IMU) separated by standstills. To find the sensor errors the cost function is defined in terms of orientation differences between accelerometer and gyroscope reported orientations. Then this function is minimized with respect to calibration parameters, that include scale factors, axis non-orthogonalities, biases and misalignment between gyroscope and accelerometer triads. The proposed method has been verified through Monte-Carlo simulations using synthesized IMU data. Besides the method was tested on real data from MPU-9250 sensors. In both cases, the method was proved to properly find calibration parameters. The simulations revealed that the differences between true and estimated sensor error parameters were less than 0.1% of their true value. The experiments using real and simulated data showed the significant elimination of orientation error after calibration. Moreover, the contribution of gyroscope scale and non-orthogonality errors to the total orientation error was estimated. The method implementation in Python together with the inertial data simulator and real sensor data are provided publicly**Reproducible research: all files and software for data processing used in experiments and simulations are available under an open-source license at https://github.com/mikoff/imu-calib..

Land vehicle navigation based on inertial navigation system (INS) and odometers is a classical autonomous navigation application and has been extensively studied over the past several decades. In this work, we seriously analyze the error characteristics of the odometer (OD) pulses and investigate three types of odometer measurement models in the INS/OD integrated system. Specifically, in the pulse velocity model, a preliminary Kalman filter is designed to obtain accurate vehicle velocity from the accumulated pulses; the pulse increment model is accordingly obtained by integrating the pulse velocity; a new pulse accumulation model is proposed by augmenting the travelled distance into the system state. The three types of measurements, along with the nonhonolomic constraint (NHC), are implemented in the standard extended Kalman filter. In view of the motion-related pulse error characteristics, the multiple model adaptive estimation (MMAE) approach is exploited to further enhance the performance. Simulations and long-distance experiments are conducted to verify the feasibility and effectiveness of the proposed methods. It is shown that the standard pulse velocity measurement achieves the superior performance, whereas the accumulated pulse measurement is most favorable with the MMAE enhancement.
