  • Aircraft navigation using MEMS IMU and ground radio beacons
    • Authors: G. I. Emel’yantsev; A. P. Stepanov; B. A. Blazhnov
      Pages: 173 - 180
      Abstract: Navigation of a small-sized aircraft is discussed using integrated data from MEMS-based IMU and receiver of ground radio beacon signals within an integrated tightly-coupled orientation and navigation system (IONS). IONS algorithms and errors in orientation and navigation parameters are considered both during prestart IMU error calibration with external aiding over a limited time interval and during simulation of aircraft flight along a preset path. Data in IONS are integrated using the extended Kalman filter (EKF). In simulation modeling of IONS functioning algorithms in Matlab (Simulink) we used data of bench tests of MEMS sensors developed by Elektropribor.

  • Indoor laser-based SLAM for micro aerial vehicles
    • Authors: C. Doer; G. Scholz; G. F. Trommer
      Pages: 181 - 189
      Abstract: This article presents a laser-based 2D simultaneous localization and mapping (SLAM) algorithm for indoor environments. An adaption and optimization of a ground vehicle SLAM solution (TinySLAM) for the use with Micro Aerial Vehicles is proposed. Optimizations of the map update strategy and a motion model improves the accuracy strongly. An extension to 3D mapping is introduced. The presented algorithm is tested with simulated and real world data. The optimized SLAM solution maps a whole floor of an office building very accurately and achieves embedded real-time capability.

  • Motion monitoring based on a finite state machine for precise indoor
           localization
    • Authors: N. Kronenwett; J. Ruppelt; G. F. Trommer
      Pages: 190 - 199
      Abstract: This paper presents a precise stance detection method for accurate personal localization using a foot-mounted inertial measurement unit. The exact classification of the stance phases of the foot is realized with a finite state machine (FSM), which separates the human gait circle in different sub-states. The FSM-based approach provides high accurate and robust detections of Zero Velocity Updates (ZUPTs) which can be applied to the navigation filter. We use a constraint stochastic cloning (SC) Kalman filter to show the performance of the high precise ZUPT intervals with real world sensor data including forward, backward and staircase motion. Even for the movement type running and the signals of an ultra-low cost inertial measurement unit we achieve with our motion monitoring system a position estimation with an average error of less than 1.5% of the travelled distance.

  • Influence of nonuniform thickness of hemispherical resonator gyro shell on
           its unbalance parameters
    • Authors: M. A. Basarab; V. A. Matveev; B. S. Lunin; S. V. Fetisov
      Pages: 97 - 103
      Abstract: Formulas for the unbalance components of the hemispherical resonator gyro (HRG) with a shell of variable thickness in meridian direction are obtained. Various laws of thickness reduction from the pole to the edge are considered. It is shown that for the second form of excited oscillations, relative error in unbalance components (with the thickness variation neglected) can reach 10–15%. The obtained formulas for unbalance components, taking into account the variable thickness of the shell, can significantly improve the accuracy of HRG balancing, which is the most important process in the manufacture of medium and high precision devices.

  • Dead reckoning using an attitude and heading reference system based on a
           free gyro with equatorial orientation
    • Authors: Ya. I. Binder
      Pages: 104 - 114
      Abstract: The paper develops an earlier proposed approach to the construction of a geographically oriented horizon trihedron nonperturbed by inertial accelerations to aid navigation dead reckoning. The method developed by the author is called gyroscopic orientation with correctable pendulum. The proposed scheme is implemented using a trihedron of accelerometers and a free (uncontrolled) gyro with equatorial orientation. Special attention is given to the Schuler filter, which not only provides “absolute” nonperturbility of navigation dead reckoning but also makes it possible to formulate the problem of its autonomous error estimation to the accuracy determined by the gyro drifts in the steady state. The problem of occasional correction of “azimuth” heading during in situ observation is also considered.

      Pages: 121 - 128
      Abstract: The procedure proposed for studying the errors of MEMS accelerometer triad reduces the test duration as compared with traditional methods and allows estimation of mutual geometrical arrangement of sensors in the triad. The proposed approach consists in studying the static characteristics of sensors in oscillating angular motion mode and estimates error coefficients in mathematical model of accelerometer readings along with location of accelerometer triad in the closed IMU casing. Results of studying the errors of MEMS accelerometer triad are presented.

  • Comparative evaluation of IRNSS performance with special reference to
           positional accuracy
    • Authors: M. P. Vasudha; G. Raju
      Pages: 136 - 149
      Abstract: The Indian Regional Navigation Satellite System (IRNSS) is a seven-satellite constellation developed by Indian Space Research Organization (ISRO), India. IRNSS provides two services, with the standard positioning service open for civilian use, and for authorized users (including the military) with an assured absolute positional accuracy. IRNSS is designed to cover all the parts of India and also extending beyond the Indian borders. The coverage area of IRNSS with routes of satellites means and includes area covering entire Pakistan, Afghanistan, most of China and Middle East along with Indian Ocean. IRNSS downlink signals have two bands: S1 band and L5 Band. Presently Indian users are dependent on the civil GPS signals with a positional accuracy of 5 m. IRNSS system is intended to provide an absolute position accuracy of (i) better than 10 m throughout Indian landmass (ii) better than 20 m over the Indian Ocean and (iii) approximately in a region of 1500 km around India. There are 15 ground stations across the country responsible for operating and/or monitoring the IRNSS seven satellite constellation. A comparative analysis of IRNSS and GPS navigational satellites shows that the IRNSS consists of sufficient number of satellites for regional navigation system and it can also exhibit better performance. The main parameters selected for our study are orbital characteristics, position accuracy and positional error including Circular Error Probable (CEP), Altitude variation, Geometric Dilution of Precision (GDOP) with respect to Number of Satellites (NSAT), variations in Carrier to Noise (C/N0) ratio and scintillation effect of both GPS and IRNSS satellite systems. Our analysis showed that IRNSS systems shall be used as stand-alone systems.

  • Monocular vision-based range estimation supported by proprioceptive motion
    • Authors: P. Davidson; J.-P. Raunio; R. Piché
      Pages: 150 - 158
      Abstract: This paper describes an approach for fusion of monocular vision measurements, camera motion, odometer and inertial rate sensor measurements. The motion of the camera between successive images generates a baseline for range computations by triangulation. The recursive estimation algorithm is based on extended Kalman filtering. The depth estimation accuracy is strongly affected by the mutual observer and feature point geometry, measurement accuracy of observer motion parameters and line of sight to a feature point. The simulation study investigates how the estimation accuracy is affected by the following parameters: linear and angular velocity measurement errors, camera noise, and observer path. These results impose requirements to the instrumentation and observation scenarios. It was found that under favorable conditions the error in distance estimation does not exceed 2% of the distance to a feature point.

      Abstract: The paper focuses on a ship motion prediction method. Unlike the other approaches, this prediction method with extended prediction duration uses dynamic models of the ship and disturbances. Identification procedure is used to determine the current parameters of ship motion dynamic model, and disturbance model is adjusted for certain motion conditions. Modeling results with the analysis are given, and the prediction of ship roll and pitch angles by the data obtained at the tests of a heavy aircraft carrier.

      Abstract: The paper presents a multiloop system for tracking the radionavigation parameters of navigation satellite signals in the user equipment. Comparative analysis of accuracies of traditional tracking system with discriminators and filter in the tracking loop and the proposed system without discriminators is conducted. RMS errors of estimates and the probability of signal acquisition are studied under various SNR values. The proposed scheme is shown to outperform the traditional tracking system with discriminators.
