摘要/Abstract

摘要： 针对微小型组合导航、制导与控制系统对其导航计算机处理能力、体积、功耗及适用性等方面的要求，设计一种嵌入式高性能导航计算机系统.采用ARM芯片AT91RM9200和DSP芯片ADSP21364双组合处理器方案，进行外围电路的扩展，能够高效的完成信息采集、实时导航解算、卡尔曼滤波及发送控制指令任务.设计注重了导航计算机系统的可扩展性，可应用于多种微小型GPS/SINS，DGPS/SINS/MC等组合导航、制导与控制系统.较之传统的导航计算机，突出了体积小，功耗低及适用性强等特点.

Abstract: A high performance navigation computer based on the embedded system is designed to satisfy the requirements of processing ability, volume, power and applicability of microintegrated navigation, guidance and control system. The computer can accomplish real time navigation algorithm and Kalman filtering by effectively collecting information from sensors, and transmits controlling instructionsby using ARM chip AT91RM9200 and DSP chip ADSP21364 as processors to extend peripheral memories and communication interfaces. The computer can be used in GPS/SINS，DGPS/SINS/MC due to its expansibility. The design is outstanding for the characteristics of small shape, high efficiency and low power compared with traditional ones.
