Ship Navigation Information Processing System

Simply rely on inertial devices improve gyro,accelerometer accuracy, inertial navigation systems to improve navigation accuracy parameters of the high cost of integrated navigation method provides a good solution.Integrated navigation information system deal with the development,implementation of the submarine inertial navigation information and high-precision attitude determination GPS MS860-based navigation information and submarines underwater navigation information in real-time acquisition.Both synchronous real-time portfolio information made a deal,at the same time using serial RS-422/485 protocols and network TCP / IP protocol to send the external real-time for other system applications.At present,the domestic real with INS,high-precision attitude determination GPS MS860-based and underwater navigation project portfolio information or gaps in implementation.Deal with navigation information system project has developed prototype completed,filled this gap.Papers mainly deal with navigation information system analysis and design, according to the system to achieve the main function and to achieve performance targets,carried out the principle of analysis and design of hardware and software. Information processing systems to complete system all the necessary navigation equipment external signal conversion,processing,sending and display;the change of control of parts of the control,monitoring and management.Its operation, acquisition,solving the normal or not will directly affect the job performance of the entire system must be able to work long hours reliable.Hardware has an internal board to select the main research and design,with emphasis on angle conversion module implementation,internal time synchronization module implementation and chassis,panel design,the conversion treatment centers selected PC/104 bus.System in the inertial technology research and engineering application of the results based on specific project characteristics,study and master the navigation information underlying agreement,many realize DOS operating system protocol communication RS422 serial port,LAN communications,the completion of many real-time mission control and associated communications deal.Systematic comparison of different rotary module filtering method,and give the effect of filtering;for INS navigation information and the information MS860 features,the design position,posture combination of indirect output Kalman algorithm,and using the measured dynamic data filtering treatment,has give the value of the deal with the results of system optimization and performance conclusions.Designed rotary converter used in collecting smoothing filtering strategies,and in accordance with the MS860 provides information,design the optimal Kalman(Kalman) filter;and sea test data measured filter treatment,give the results of treatment.
