摘　　要：随着舰船上的武器系统和观测系统的数量不断增多及对其的精度和可靠性等要求的不断提高,对精确的局部姿态基准需求也不断增长。该文给出了用于消除大型舰船甲板变形给各战位点带来影响的分布式捷联姿态基准的结构,讨论了分布式捷联姿态基准中基于实时多任务操作系统的姿态算法的实现方法,包括:实时多任务操作系统环境下组合式捷联姿态基准算法应用程序的多任务确定,组合式捷联姿态基准算法中各任务的实现等。采用文中所述方法实现了一种实用的组合式捷联姿态基准算法,算法的仿真结果证明了文中所述方法的正确性。Due to the increasing number of weapon systems and observation systems for navy vessels and the better-required performance, the number of separate attitude reference is also increasing. On the basis of putting forward the structure of distributed strapdown attitude reference system （DSARS） which is used to compensate the influence brought by the deck deformation of large-scale navy vessels, the implementation of attitude algorithm in DSARS based on the real-time multitask operating system is discussed. The multitask establishment of the integrated strapdown attitude reference algorithm and the accomplishment of each task are included. A useful integrated strapdown attitude reference algorithm is realized by the way discussed here and the simulation result proves the correctness of the program method.
