针对航空航天、军工领域内火箭、导弹等飞行器的有关结构部位在飞行工况下脱落或分离的定位需求,设计了一套高性能的弹载定位系统。BDM910模块作为该系统的首要功能核心,通过RNSS模块实时与卫星通信获取自身位置信息,通过RDSS模块可以实现对地面北斗接收终端的短报文通信。GD32F450VIT6单片机对此过程中产生的信息数据进行提取、编帧处理。系统在一定程度上解决了武器装备、运载火箭等大型仪器设备在高温、高冲击、超高速等恶劣环境下工作的定位问题,经静态与动态综合性环境试验考核,定位误差在5 m左右,且集成度高,整机体积仅为200×140×104 mm³大小,具有定位精度高、通信实时性强的特点。

In view of the positioning needs of rockets,missiles and other aircraft in the field of aerospace and national defense industry that fall off or separate under flight conditions,a high-performance missile positioning system is designed.As the primary functional core of the system,the positioning module obtains its own position information through real-time communication with the satellite through the RNSS module,and can realize short message communication to the ground Beidou receiving terminal through the RDSS module.GD32F450VIT6 microcomputer extracts and frames the information data generated in this process.To a certain extent,the system solves the positioning problem of weapons and equipment,launch vehicles and other large instruments and equipment working in high temperature,high impact,ultra-high speed and other harsh environments,after static and dynamic comprehensive environmental test assessment,positioning error is about 5 m,and high integration,the whole machine volume is only 200×140×104 mm³ size,with high positioning accuracy,strong communication real-time characteristics.
