摘要
面对未来信息化、电子化战争复杂的电磁环境和高速、超高速精确制导武器发展需求,传统GPS/INS组合导航技术很难满足武器性能指标的要求。而GPS/INS深组合导航系统能在高动态和复杂电磁环境下为精确制导武器提供稳定、可靠、精确的导航信息,实现精确制导武器在复杂战场环境下对目标的精确打击。因此GPS/INS深组合技术成为近来人们的研究热点。深组合技术除了传统意义上利用GPS接收机信息修正INS之外,同时,采用INS导航数据还能对GPS接收机载波跟踪环路进行外部辅助,剔除信号中的动态信息,减小GPS接收机载波跟踪环对信号的跟踪范围,压缩环路带宽,提高接收机在高动态环境下工作稳定性和接收机抗干扰性能,以保证组合导航系统的可用性和可靠性。
To face up with the complex electromagnetic environment of informational and electronic warfare in the future and to meet the requirements for high-speed,ultra-high-speed precision-guided weapons development,since the conventional GPS/INS combined navigation technology is difficult to satisfy the performance requirement of weapons,the deeply-coupled GPS/INS navigation system can provide the precision-guided weapons with stable,reliable and accurate navigation information under the high-dynamic and complex electromagnetic conditions to achieve the target precision strike by the precision-guided weapons under the complex theater environment.Therefore,the coupled GPS/INS technology has become hot research point.The GPS/INS coupled technology,besides use of GPS receiver information for correction INS,meanwhile,is in the adoption of INS navigation data for external aid to the GPS receiver carrier tracking loop,eliminating the dynamic information in the received signals,decreasing the tracking range of the GPS receiver carrier tracking loop for the signals,compressing the bandwidth of carrier tracking loop to improve the receiver working stability and anti-jamming performance under high-dynamic conditions so as to ensure the usability and reliability of the coupled navigation system.
