The paper presents the results of development of the precision gyro device complex, designed to be used as part of control systems for carrier rockets and boosters, and also basic inertial measuring devices involved in this complex. These devices are a single-degree-of-freedom gyro unit and a gyroscopic integrator of linear accelerations with gas-static support. Essential advantages of the gas-static support usage when designing precision inertial devices as against the floated support are stated. The results of designed complex operation as part of the booster "Briz-M" are given in the paper.

The paper presents the results of works carried out in Ramenskoye Planning and Design Bureau, Physical and Technological Institute of RAS, JSC “Micron” factory” on development of the monolithic silicon micromechanical acceleration sensor to be used in navigation and control systems. The route technology of manufacturing a microsensor is considered in the paper. The results of testing acceleration microsensor specimens at different stages of the technological process are cited.

The paper deals with the results obtained in laboratory and ship trials of goniometric equipment for a user of satellite navigation systems GLONASS and GPS - MPK-11 - developed in SRI of Radio Engineering of Krasnoyarsk State Technical University with a view to determine prospects of using this equipment jointly with the miniature strapdown measuring module developed in CSRI "Elektropribor". A complexing filter is introduced on the basis of experimentally obtained error characteristics of satellite receiver and inertial measuring instrument. The results of integrated system error simulation using trial data are given in this paper.

Main technical characteristics and principles of Universal automatic identification system (AIS) functioning are given. AIS will be applied by maritime users since 2001 according to IMO Resolution MSC.74(69). It is known that radar is the main source of information in Vessel Traffic Monitoring System (VTMS) which monitors the area of maritime administration responsibility. However, VTMS provides a raw radar picture which has some disadvantages under definite circumstances: the detection range is rather short, especially for small targets; with intensive sea or rain clutter the target may not be detected; targets behind the islands or river turns are not visible; target's manoeuvre is not instantaneously detected due to the filtering and smoothing algorithms, etc. Hence the necessity occurs to overcome these drawbacks in some manner. One of the ways to remove these drawbacks is to apply the universal automatic identification system (AIS) which being the transponder transmits practically in real time scale data on the ship's coordinates determined with differential navigation satellite systems (GLONASS/GPS), such as heading, course and speed over ground. Such system is virtually free of these disadvantages. Besides, it enables automatic identification of targets, which VTMS cannot do.

TRANSAS ideology on integration of AIS information on the shipborne INS, radar, ECDIS displays is proposed. Demo test results are described.

Creation results and application prospects of a multifunctional navigation equipment for users of global navigation satellite systems including GLONASS and GPS, which provides objects' spatial orientation determination, are discussed in the paper. The global navigation satellite system (GNSS) GLONASS provides a high precision navigation for moving objects. Along with the determination of coordinates and velocity as well as user's precision time, GNSS application is promising to determine objects' spatial orientation (angles of azimuth, pitch and heel). Over 10 years Krasnoyarsk enterprises have been cooperating successfully in the field of development and introduction of users multifunctional navigation equipment (UNE) for the GLONASS and GPS GNSS.

Radio Frequency Interference such as TV and FM harmonics, which occurs frequently in the environment of a GPS receiver, affects adversely its accuracy. This paper deals with the problem of interference mitigation. Classically the precorrelation techniques used for interference excision result in a prewhitening filter. These techniques do not take the statistical properties of the interference into account. Here we apply a method based on the weak signal detection theory to define the optimum receiver in the presence of non-gaussian noise. In that case the receiver differs from the conventional one. It includes a non-linearity law applied to the complex IQ signal.

This paper presents the non-linear filter and the associated receiver is compared to the conventional system. It includes a theoretical analysis that allows to evaluate the method for continuous, swept and pulsed sinusoidal interference. Also is carried out a simulation of the receiver which includes the non-linearity estimation whose shape is adapted to the jammer using a blind technique.
