平台式惯导系统初始对准及导航的软件设计

方位锁定小转角对准法是近年来提出的一种新的平台式惯导系统初始对准法。除限于实验设备等因素外,还由于采用汇编语言编制惯导系统软件是一项极为繁琐的工作,需要花费大量的时间和精力;因此,在此之前,本方案和很多其它方案一样,所能做的仅仅是数学仿真。本文的目的就是通过对这种初始对准方法进行软件设计与研究,力求编制一

SOFTWARE DESIGN OF ALIGNMENT AND NAVIGATION OF PLATFORM INS

The software design of “Locked Azimuth-Gimbal and Little Rotation Angle Alignment”is discussed. The software is worked out with Intel 8086 assembly language. Thereby, an utility program has been obtained that will be widely fit for the design of the alignment and navigation of platform inertial navigation system. At the same time, some problems on programming are specially studied, such as calculating the modulation-width pulse number of current applied to gyro torquer, salving differential equation with assembler and compensating the double precision with variational proportionality factor. The test results obtained from an actual inertial navigation are given at the end of this paper.
