RUSSIAN NAVIGATION AND INFORMATION SATELLITE SYSTEM

  1. V. Dvorkin, V. V. Kurshin, A. A. Povalyaev, A. A. Kotyakhov

 

The paper presents the «Russian Navigation and Information Satellite System» project. This system generates signals that contain navigational data on its ground segment and transmits them to users with the help of data relay satellites. Besides the navigational data contained in the signal, the system also relays communicational messages. The authors analyze the premises of this system’s creation, put forward an approximate composition, signal structures and frequency bands for this system.

 

Keywords: GLONASS, GNSS, GPS, combination of navigation and communication, navigation and information satellite system, navigation satellite system, RNISS, SBAS

 

  

POTENTIAL CHARACTERISTICS OF THE OPTIMAL FILTERING

FOR THE NAVIGATION SIGNAL CARRIER TRACKING SYSTEMS

 

  1. N. Voronchikhin

 

This article deals with optimal filtering algorithms for the navigation signal carrier tracking systems. Besides recursive filtering and extrapolation, the optimal filtering contains smoothing which could increase the chances of obtaining the best possible result not only for estimation accuracy but for noise-resistance as well. The paper includes derivation of potential characteristics of accuracy and noise-resistance of smoothing algorithms. In addition, some statistical modelling results are given in the article.

 

Keywords: optimal filtering, carrier tracking, optimal smoothing, noise-resistance

THE APPROACH TO SYSTEM-AGGREGATIVE NAVIGATION SYNTHESIS

FOR AN AUTOMATIC MOVABLE OBJECT

  1. V. Baushev, L. V. Tananikina, V. I. Yakunin

 

The approach to the external (system-aggregate) design of navigation support for an automatic movable object is proposed. This approach is based on the methodology of the targeted processes effectiveness theory. The example is considered and expression for determining the values of the performance indicator, depending on the values of the parameters of the navigation system and the process of its application, is derived.

INTEGRATION OF DISTRIBUTED INERTIAL NAVIGATION SYSTEMS BUILT AROUND FIBER-OPTIC AND MICROELECTROMECHANICAL SENSORS

A. V. Chernodarov, A. P. Patrikeev, S. A. Ivanov, I. I. Merkulova

Basic features of the integration of inertial and satellite navigation systems (ISNS), which are built around fiber-optic and microelectromechanical sensors are considered. New properties of the above systems, which are connected with their unification into a single structure are justified. The possibility for the raising of both their accuracy characteristics and their reliability characteristics is shown. The proposed approaches to the realization of such a possibility for the ISNS rely on the method of vector matching and Kalman filtering mathematical apparatus. The studies conducted corroborate the fact that it is possible and expedient to apply the proposed technology to improve accuracy characteristics of the combined ISNS.

Keywords: fiber-optic sensors, inertial navigation systems, micromechanical sensors, system integration.
