为提高导航的精度和实时性,设计了基于DSP和FPGA的导航计算机模块,成功实现了低成本、小型化的捷联惯性导航系统.通过描述硬件的设计原理和软件的框架及流程,简要介绍了系统的设计和实现方法.经验证,该系统达到了导航定位的性能和精度要求,姿态、位置和速度等参数可以有效融合多传感器的导航信息,能满足导航计算机在处理能力、体积、功耗和适应性等方面的要求.%Aiming at improving the precision and real-time performance of navigation, a navigation computer module based on DSP and FPGA was designed, and the strap-down inertial navigation system with low-cost and miniaturization was made up successfully. The design and implementation methods of the system are briefly introduced while the hardware design theory and the software architecture (including its flow path) are described. The verification results of the system shows that the system can meet the performance and accuracy requirements of navigation and orientation, efficiently fuse the navigation information from multi-sensor with flight attitude, position, speed and other parameters, and satisfy the navigation computer with its processing ability, volume, power consumption, adaptability and other performance parameters.
