Much work has been accomplished over the past 20 years in the developing and testing of an Auto GCAS. In the past three years, a Fighter Risk Reduction Pro- gram (FRRP) has been undertaken by the Air Force Research Laboratory (AFRL) at Wright Patterson AFB. This program is a joint effort between AFRL, NASA Dryden, Lockheed Martin Aeronautics, and the Air Force Flight Tests Center. The FRRP has advanced Auto GCAS technology to a level now capable of production transition. Results of this effort will be discussed in this paper. The F-16 test air- craft is shown in Fig. 1. Controlled Flight Into Terrain (CFIT) is defined as collision with terrain, water, trees or a man-made obstacle during flight prior to planned touchdown. CFIT includes mishaps where the aircraft is controllable and the pilot is actively control- ling the aircraft or the pilot’s ability to control the aircraft is reduced due to spatial disorientation. CFIT also includes mishaps where the aircraft is flown in con- trolled flight to a point where it is no longer possible to avoid unintended ground impact (e.g., attempted maneuver with insufficient altitude or airspeed, low altitude over bank or flight into a box canyon), regardless of subsequent pilot reaction (e.g., add power, maneuver to avoid terrain, etc.). Prevention of CFIT mishaps utilizing Auto GCAS will be presented. The requirements for Auto GCAS and the order of importance of those requirements will be discussed in this paper.

The article describes the range of aircraft location vertical finders to determine the pitch and roll angles. The mentioned devices reflect the main stages of the attitude control system development throughout the history at the Control Device Depart- ment of the Tula State University, ranging from classical platform systems to mi- cromechanical and pyrometer strapdown attitude reference systems. A multifunctional attitude gyroscope based on two two-degree-of-freedom gyros driven by electric gyro motors has been discussed as a classical platform attitude gyroscope. Strapdown vertical references are represented by system samples based on micro- mechanical inertial sensors and pyrometer detectors. The article provides the specifications of the vertical references concerned and performs the comparative analysis thereof. It also shows the advantages and disadvantages of each of these systems.

The structure of the mobile inclinometric station performing continuous inclinometric survey of the relative position of the wellbore trajectories of the underground mine borehole group, and its algorithmic description and software are considered. New engineering solutions obtained when designing the stations are analyzed. The results of the station tests under excavation conditions are presented.

A random process value prediction problem is considered. In this problem the assumption is made that the uncertainties generating the process analyzed have a statistic nature and that observations are carried out with unknown but bounded noise. A randomized algorithm filtering arbitrary external noise in observation is pro- posed. Examples of simulation in comparison with traditional approaches are presented.

The given work develops the researches [1-4, 6], devoted to designing, creation and research of the superminiature micromechanical gyroscope (SMMG) (fig. 1). The purpose of work are maintenance of effective functioning of the SMMG. For achievement of the purpose are delivered and solved the following problems. – Construction and research of mathematical models for calculation and the analysis of frequencies own oscillations (1)-(5) and for estimations of strength and vibration strength (6), (7) distributed systems SMMG with rectilinear elastic elements (fig. 2). – Construction and research of mathematical models for calculation and the analysis of frequencies own oscillations (8)-(18) distributed systems SMMG with curvilinear elastic elements (fig. 3-5). – The analysis of influence of the technological errors of manufacturing elastic elements on characteristics support (table. 1, fig. 6) is conducted. During realization of activity it is developed supporting software. The conducted analysis of bilateral and console elastic support SMMG has allowed to reveal the main features and frequency properties of such support. On the basis of the conducted researches of elastic support, the capability of creation superminiature (by a volume <0,2 mm3 without of service electronics) the mi- cromechanical gyro with set frequency and strength properties is shown.

The phenomenon of dead band in laser gyroscopes is widely known. However, as it has been found out recently, the dead band also occurs in fiber-optic gyroscopes (FOG). The issues related to the problem of dead band in interferometric close-loop FOG are considered. The causes of FOG dead band appearance and methods of its suppression are described and analyzed on the basis on literature review. FOG dead band identification and estimation procedure are discussed. The dead band values for FOG developed in Russian Federation (by RPC OPTOLINK Ltd., JSC Perm Research and Production Instrument Company, Concern CSRI Elektropribor, JSC, jointly with National Research University of Information Technologies, Mechanics and Optics) and other countries (Honeywell, IXSEA) are given.
