A map-aided navigation problem is formulated in the Bayesian framework to provide a basis for algorithms classification. Algorithms involving preprocessing of measurements aimed to improve the accuracy of the field profile used in the comparison with the map are discussed. An algorithm without measurements preprocessing and profile estimation is briefly described. The results are considered to illustrate the operation and advantages of such an algorithm by an example of a gravity-aided navigation in a weakly anomalous region.

A numerical-analytical method for solving the dynamic equation of an elastic ring resonator mounted on an arbitrarily rotating base is proposed. The method is based on the combined use of the generalized Bubnov-Galerkin (Kantorovich) method in angle and the direct method (Rothe) in time variable. In contrast to the previously presented results, the initial model takes into account terms proportional to the square of the angular velocity of the base and angular acceleration; it is also assumed that the resonator parameters are not uniform in angle. The given example allows us to conclude that the method is suitable for the case of high-intensity dynamic processes (large square of angular velocity and angular acceleration), in particular, the effect of reducing the influence of the defect of the resonator parameters by the 4th harmonic on its dynamics is shown.

Hybrid inertial navigation system with three rotating axes involves the advantages of platform navigation system, strapdown navigation system and rotatory inertial navigation systems, which can improve navigation and positioning accuracy substantially. A comprehensive study of the error propagation properties and error compensation mechanism of rotatory inertial navigation system is conducted. On the basis of this theory, combined with the analysis of the traditional rotation scheme, a reasonable scheme of system error compensation based on the geographical coordinate system is determined. The rotation scheme relative to the geographic frame cannot eliminate the coupling items between the errors of the gyroscope and the Earth rotation, then a three-axis rotation scheme relative to inertial frame is proposed. The simulation is conducted to verify the rotation scheme, and the results are compared with the rotation scheme relative to the geographical frame. Results show that the inertial frame modulation scheme can reduce the navigation error caused by coupling items between the errors of the gyroscope and the Earth rotation obviously.

We present a review of studies that were conducted by the MicroSystems Laboratory at UC Irvine on ZUPT-aided pedestrian inertial navigation. Our most recent results include: adaptive ZUPT detection, IMU mounting position optimization, residual velocity characterization, IMU error calibration, and navigation error prediction. With all the efforts above, a robust and accurate ZUPT-aided pedestrian inertial navigation implementation was demonstrated. The navigation bias was reduced by 10×, and a position error of less than 1% of the total length of trajectory was demonstrated with an industrial-grade IMU.

This paper proposes two methods for calibrating triaxial magnetometers. Both of them calibrate these sensors with more general assumption of noise on three axes than previous state-of-the-art methods. The first method estimates bias and rotation parameters more accurately and the second method yields a better estimate for the scaling parameter than the state-of-the-art method subMLE. The computational time of the latter is also 43 times faster than subMLE, which allows this method to be applied in devices with low-computational resources (e.g. smartphones). Furthermore, the second method yields more robust heading angle estimates compared to subMLE. This result implies that the second method can be applied in light-weight inertial measurement systems, for which the orientation of the device is vital information for pedestrian dead reckoning system.

Identification of parameters of a solid-state wave gyroscope in the forced and free-run modes under nonlinear resonator oscillation is considered. By using the Krylov-Bogolyubov averaging method, calibration equations are deduced for determining the mathematical model coefficients. These coefficients contain an oscillation nonlinearity coefficient and parameters characterizing resonator defects including frequency difference and damping anisotropy, orientation of main axes of stiffness and dissipation. Suggested identification methods allow us to perform testing at large oscillation amplitudes. Numerical simulation of parameters identification is carried out. It is shown that accounting for nonlinearities in case of large oscillation amplitudes significantly increases the accuracy of parameters identification.

The report presents the analysis of opportunities of aircraft navigation systems development with regard to the aid of onboard geophysical fields measurements. We consider some prospective systems which today are not widely used: magnetic gradiometers that measure stationary magnetic field gradient, gravity gradiometers that measure gravity field gradient, electromagnetic systems that measure the alternating part of magnetic field. We discuss the main tasks that have to be solved during airborne measurements of these parameters. We give a review of algorithms and hardware solutions. We present some examples of onboard measurements and estimate the possible navigation accuracy.
