Design Method For Virtual Test System For Verification Based Transfer Moving

With the development of space-based tactical and strategic weapons,weapons before launching the initial alignment technology put forward higher requirements,the traditional optical sight,time alignment methods such as self-aligning takes too long,and aligned to achieve in the stationary state,the initial space-based weapon systems transmit alignment needs to be at high dynamic conditions,traditional initial alignment method has been unwell for space-based weapons systems.Fast and accurate completion under dynamic conditions of high dynamic initial alignment has become a key technology of modern weapons.For several common Moving Base Transfer Alignment Method comparative analysis,we found that if you use "speed + profile" matching algorithm that can quickly and efficiently transfer alignment.In this paper a derivation operation relationship equation between the main INS and the sub-INS,and provides a method of compensating the lever arm effect;establishes the error propagation equation the main and sub inertial navigation systems;and established based on "Velocity + Attitude" matching the observation equation;Kalman filter design; prepared Alignment simulation program;the validity of the matching algorithm.Modern distributed computer simulation technology and fast development of parallel computing technology in the aerospace field,distributed simulation technology is increasingly being applied to the development and demonstration of technologies.Due to the increasing complexity of modern weaponry system and become larger, and therefore the complexity of modern weapons and equipment for system simulation test management system is also increased. In this paper, this trend has developed virtual test simulation platform.In the second half of this article first introduces the virtual test platform functionality and composition;analysis of the overall architecture and the corresponding function of each module software; and finally,the key technology platform for a detailed description and show the interface effects software.The system uses a client / server(C/S) architecture,information exchange between the use of local area network communication between client and server implementation and management of child nodes of the simulation.And may generate a virtual test configuration file, can be realized quickly duplicate complex test configuration and remote control.The software for different virtual test, support reallocation model file in the node.After the software is written,the test results and practical applications of the software in virtual test showed virtual test platform to build on the successful realization of the test tasks, management and control of the test run,the software is relatively stable,people and interface friendly.
