摘要
针对定位导航与授时系统的微小型化、一体化应用需求,提出了一种微型定位导航授时(Micro-PNT)系统集成方案,该方案是微小飞行器在GNSS拒止条件下可靠工作的有效解决手段。系统基于电路刚挠一体化工艺和器件空间布局优化技术,集成了MEMS惯性仪表、芯片级原子钟、处理器、电源芯片等功能器件,实现了系统的微型化、一体化。文中阐述了系统的集成架构和软件工作流程。通过系统样机的研制,验证了集成方案的可行性。通过分析系统样机的集成特点,指出其微型化存在的问题。最后,结合关键器件和三维微系统集成技术发展,给出了Micro-PNT微系统集成架构。
For the miniature and integration of positioning navigation and timing system, an integration solution of Micro-PNT system was proposed, which is an effective solution for micro air vehicle under GNSS denial environment. MEMS inertial instruments,chip-scale atomic clock,micro-processor,power chip and other chips were integrated based on rigid-flexible integration processing and Layout optimization technology. The integration frame and software flow were presented in detail. Designing was validated through system production. Problems of the integration for micromation were proposed through analyzing the integration form. Finally, microsystem integration frame of micro-PNT was proposed which was based on key parts and 3 D microsystem integration processing in the future.
