Abstract:The concept and features of image navigation are reviewed in the paper. The typical application of image navigation in robot navigation,missile navigation and terrain aided navigation is introduced. Also, the paper discusses the feature of the image navigation, as well as the advantages and limitations in the different application field. Especially, the image navigation used in the aircraft is analyzed in detail. A prediction about the prospective and development of image navigation is given in the end.

Abstract:In this paper, general situation of the development about torque transducers is briefly introduced, and the advantage and disadvantage of all kinds of torque transducers are compared, it introduces fully about the up to date torque transducers, some key technology and the research hotspot are discussed at the same time.

Abstract:Based on the measurement process and learning of measuring error, a novel method of using the limit point to evaluate the static characteristics of the nonlinear transducer is presented. The two models to calculate the static characteristics of the nonlinear transducer by using the above method are given. And the calculation and investigation are provided by a set of the calibrated data for an electrical eddy nonlinear displacement transducer.

Abstract:Aiming at the coordinate transformation in the station movement of large scale dimension measurement,a least square coordinate transformation model and the parameter solution based on mode searching are given. Experiments show that this method is correct and practical.

Abstract:In this paper the construction of current loop designed for servo of Airborne Electro opitcal Pointing and Tracking Platform(AEPTP)is presented and an insight analysis into the design of current regulator is mainly discussed .At last a simulation of the modeled current loop is made using the MATLAB.

Abstract:The paper introduces the conception of machine vision,discusses the application of the airborne monocular camera machine vision in the system of auto landing on deck of UAV.On the basis of quick detection of the front naval ship and beforehand calibration of camera,using the theories and methods of machine vision,the intrinsic parameters of camera and projective geometry,the distance between the UAV and the naval ship is reckoned in the paper.Finlly it prospects the development and applications of machine vision.

Abstract:A new method of torque load and control with asynchronous motor is brought forward in this paper Torque is loaded and controlled without torque sensor and special torque loading equipment Fuzzy PID control arithmetic is used in this paper instead of routine PID,and it is better to simulate the running in,joint and exceeding test of clutch

Abstract:On the basis of the demand of manufacturing the checkout device,this paper analyzes the frequency signals of the aeroengine rotate speed and vibration,and then two signals of generating circuits are designed to simulate the corresponding signals.All above works could have a referrence to the manufacture of this checkout device.

Abstract:Taking example for the TCM 3 auto calibration system of thermocouple,the system as a measuring verification device is introduced.The system can undertake the core component part of temperature transference.Its mainly technical indexs can ensure the veracity of the measuring data.

Abstract:Through the experiment,the effects of SP formula,engine pressure,temperature and moisture of atmosphere on the plume primary smoke and the secondary smoke are studied and the essence of theory is discussed.

Abstract:In this paper, the error source of one measuring process standard deviation in horizontal direction of optical theodolites is analyzed. The combined standard uncertainty and expanded uncertainty of this standard are evaluated.

Abstract:In this paper, the principle of centrifuge is introduced, the mathematics model of acceleration is presented. The uncertainty of centripetal acceleration produced by the precise centrifuge is analyzed.

Abstract:An automatic test system is introduced according to flight management computer.The system hardware and its function are described,together with software and test procedure.This system satisfies the flight component maintenance manual.

Abstract:According to the demands for the evaluation of metrological security efficiency of the armament equipments,the parameters of metrological security resource are defined in classification.The index system of that based on the summary of work experience is given.
