Emergency navigation enhancement system based on aerostat platform

The invention discloses an emergency navigation enhancement system based on an aerostat platform, which comprises a space-time traceability reference platform, an aerostat platform and a user terminal, wherein the near space aerostat platform is used for broadcasting a radio ranging signal to realize emergency navigation enhancement; the system disclosed by the invention can be applied to environments such as war areas, remote mountainous areas, natural disasters and the like in which GNSS satellite signals are shielded or interfered and deceived, and particularly can provide completely independent emergency navigation service for users under the condition that satellite navigation is completely unavailable. 本发明公开了一种基于浮空器平台的应急导航增强系统，包括时空溯源基准平台、浮空平台和用户终端：利用临近空间浮空器平台播发无线电测距信号实现应急导航增强，本发明系统可应用于战区、边远山区、自然灾害等GNSS卫星信号被遮挡或被干扰、欺骗的环境下，尤其是在卫星导航完全不可用的情况下，可以为用户提供完全独立的应急导航服务。
