Engineering Physics Annotation << Back MATHEMATICAL MODELS AND THE CO-PROCESSING OF THE INFORMATION FROM VARIOUS METERS A.V. BABICHENKO S.Y. SUСHORUKOV V.K. SHKRED M.I. ORECHOV Describes the basic used in practice methods of measurement errors of different navigation systems with the joint the processing of information. At first contains a General list of measuring sensors and systems included in the information-control complexes of manned and unmanned aerial vehicles. These sensors and systems, together with appropriate computing and communications resources form the information-measuring channels for different methods of navigation: number, position, review and comparative. Given the generalized algorithm of work of the channel and the mathematical models of such channels, built on the basis of the different base systems: platform and strapdown inertial, аэрометрических, satellite, radio navigation, Doppler, radar, optical. For all these types of systems are given model errors - how in the form of expressions, reflecting the physics of work systems, and in formalized form of equations of state of linear stochastic systems. For inertial systems are given vector equation orientation errors, equations of errors the number of horizontal components of the linear speed, the expressions for the basic instrumental errors, and the equation of the relationship of these variables with the errors in the main navigation parameters. For systems aerometricheskih the error measurement of aerodynamic angles, altitude and temperature, as well as errors of an Instrument air channel base. Considered in detail by the error of the survey-impact tools: tools and methodological error ranges and the angles of sight objects, we consider the dependence of the errors of calculation of the geographical coordinates of one of the two objects (aircraft machine and визируемый target) from the errors of determination of their mutual (relative) coordinates, and Vice versa. Received detailed descriptions for information residuals between the information-measuring channels – both in the form of algorithms of residual, and in the form of a description of the internal structure of the residual between the inertial and satellite, аэрометрическим and inertial, inertial and Doppler, inertial and surveillance-aiming, inertial and radionavigation, Doppler and satellite, air. These expressions are adapted for use in on-Board algorithms integrated processing and information. Key words: information-measurement channel, the mathematical model errors, information discrepancy, the algorithm of the formation of measurements, the structure of the residual.
