Ralf Monikes, Oliver Meister, Armin Teltschick, Jan Wendel, Gert F. Trommer Performance comparison of a fixed-interval smoother and a Kalman filter for GNSS/INS integration 3
This paper compares several approaches of GNSS/INS integration. Tightly coupled and loosely coupled approaches are discussed as well as an approach that tightly integrates differential GNSS and inertial navigation with carrier phase ambiguity resolution. Hence, centimetre accuracy can be achieved with a tightly coupled system. The approach can be combined with a smoother which improves the overall system performance by means of post-processing. Measurement results show that the presented smoothing algorithm can overcome problems of poor satellite availability. It is possible to recover the trajectory during GNSS outages even together with a low-cost MEMS inertial navigation system.

Problems that arise during use of integrated navigation systems (INS) are considered. The proposed solutions permit us to take into account any changes in dynamic and accuracy characteristics of sensors by means of the appropriate coefficients of the models of errors. Under actual conditions of INS operation, the determination of current values of the parameters of the models of sensors and of an estimation filter rely on identification procedures. The results of full-scale experiments are given, which corroborate the expediency of parametric identification of the models of INS errors in real time and from flight data.
A.D. Barabanov, V.A. Osipov, V.A. Tupikov, L.S. Turnetsky On the navigation support of the remotely piloted helicopter deck landing 32
The article is considered to the problem of the providing the remotely-piloted helicopter's (RPH) deck landing. The conditions of the landing at the heavy sea are analyzed. The factors that complicate the landing are determined. The hardware composition of the landing complex, algorithms of solving the tasks of that system and estimates of these algorithms' accuracy are given. There are offered ways of the optimization of these algorithms that provides the increasing of automatized RPH deck landing's reliability and safety.
S.P. Dmitriev, A.V. Osipov Consideration of errors peculiarities for the marine integrated navigation systems under accuracy control by mathematical metrology methods 42
The paper considers the peculiarities of the statistical models which is used at present for solution of navigation problems. It is shown that these peculiarities does not allowed in mathematical metrology. It is proposed the form of accuracy requirements and an test procedure for testing these requirements. It is presented results for certainty assessment of experiences and the field of application of mathematical metrology.
D.A. Koshaev Information inspection and recovery of navigation complexes at the diversity of fault types and uncertainty of their models 47
Diversity of types of information faults in navigation complexes makes the development of algorithms for fault detection and isolation to be realized in the on-board computer complicated. Moreover, a complete list of possible types of faults may be unknown. Two algorithms are suggested to overcome these difficulties. The first algorithm presumes a set of types of faults to be known. It employs an augmented Kalman filter (AKF) that estimates a group of possible faults and allows the amount of computations to be reduced. It has been shown that the results of the AKF application allow derivation of a posteriori probabilities and estimates of particular faults as well as estimates of additional errors in navigation parameters caused by faults. These estimates can be used to recover the faulty system. The second algorithm does not require knowledge about types of faults and is intended to detect the system of the complex that has errors, anomalous in level and behavior, and to compensate for these errors. The efficiency of the algorithms developed is supported by the results of simulation and bench tests of the navigation complex including more than one inertial system.
G.M. Vinogradov, N.A. Temlyakov, I.V. Balabanov, T.V. Balabanova, V.I. Stepin Investigation of the elastic suspension design for the dynamically tuned gyroscope of GVK-16 type 60
Is shown, that the design elastic suspensions dynamically tuned gyroscope of a type GVK-16 causes, in case of force influence on the part of a rotor in a direction of an axis of own rotation gyroscope, same (tension or compression) longitudinal deformation of its elastic elements. The theoretical substantiation of influence of longitudinal force on working angular rigidity of elastic elements having variable cross section is received. With the purpose of reception of the approached analytical decision the account with an elastic element of constant section is carried out which has shown, that the tension force reduces, and the compressing force increases its working angular rigidity.
L.A. Severov, N.A. Ovchinnikova The generalized dynamics model for micromechanical gyroscopes of RR type 68
Dynamics model as a six-degree-of-freedom system has been developed for a wide class of micromechanical gyroscopes of RR type having sensors in the form of rotor. Interaction dynamics of the sensor rotary and translational motions has been analysed. The generalized model obtained makes it possible to analyse both two-dimensional and one-dimensional micromechanical gyroscopes with regard to possible asymmetry of the parameters.

Brief note

Ye.Yu. Alekhova Testing of Poisson's equations numerical solution algorithms 102
Algorithms that enable one to calculate precise readings of gyro sensors for the angular motion that simulates the change in the orientation of an object and possible angular vibration are formed. In parallel, the precise orientation of the object is determined. The algorithms are proposed to be used for the operational development and testing of on-board algorithms designed for the calculation of orientation in strapdown inertial navigation systems. The results of the operation of two different on-board algorithms are demonstrated by way of examples.
