Analysis And Design Of The Test And Control System In North Seeker

The high accuracy north seeker,makes use of inertial technique,can provides north face basis fo precision attack weapon system.It of emergence makes continent-based weapons launching system had the real maneuvering mesning.Its function is to obtain the azimuth angle with respect to beographic north amd local latirude through north-seeking measure under the comdition of the carrier staying at static state so that aligning orientation and plumbing benchmark.The Rapid North-Seeking and Orientation-Measuring system is a kind of self-comtained and independent position indicating system without relying on any outside information.It can not be interfered by the environment suchas magnetic field.It cannot be interfered by the environment such as magnetic field.It behaved premium properties under the coneition of either high or lov temperature.The system can fast determine geographic north precisely under all-day environment,and is ruitable for the high mobile operation environment especially.This has provided the good technical support for the motorized missile launch,The traditional Rapid North-Seeking and Orientation-Measuring system can promptly provide the north primary standard for the demand of missile launch.But the accuracy of survey data needs to revise, for satisying the request of the missile launch parameter.The traditional Rapid North-Seeking and Orientation-Measuring system generally adopt the computer platform using PC/104with high volume,high power consumption,fewer interfaces.Compared with PC/104,the ARMchip has incomparable merits such as low power,more interfaces,high integration level and convenient repotting of program.So,the thesis uses LPC2292 of ARM chip to comstruct the computer platform for the Rapid North-Seeking and Orientation-Measuring system. The thesis first analyse the theory of the system,the discusses the hardware design of computer platform of the system in detail.Then,the process of repotting the flush rype real-rime operating systemμC/OSⅡis given.Finally,the thesis briefly gives the process of exploiting the sortware of Rapid North-Seeking and Orientation-Measuring system.
