| 摘 要： | 捷联惯性航姿系统是一类低成本的惯性导航系统，它主要用于输出三维姿态，并能直接输出与载体坐标系一致的三轴角速率和线加速度，便于自动驾驶仪和制导系统应用。本文以实际研制的ＨＪＬ－１捷联惯性航姿系统为例，讨论了整体系统组成原理，导航算法的实现，包括四元数姿态方程、修正方式、初始对准以及计时中断的实现等；文中还介绍了由Ｃ语言编制的导航软件结构和ＣＳＤＢ通讯的处理思想；最后给出了工程样机实验情况的说明。

| Abstract: | Strapdown Inertial Attitude and Heading Reference System(SIAHRS) is one of the low cost Inertial Navigation System (INS),it is used mainly to output three-dimensional attitudes,can output directly angular rate and straight line acceleration,the direction of which is consistent with airborne coordinate frame. So,it is convenient for use by autopilot and guidance system.The paper is an example of HJL-1 SIAHRS.It discusses the composition principle of SIAHRS, and then gives some navigation algorithm,including four elements attitude equation,correct way,initial alignment and time interrupt.However,it describes the structure of navigation software programmed by C language and Commercial Standard Digital Bus(CSDB).Finally,it shows the test result about prototype SIAHRS. |
