    量子绝对重力高动态测量关键技术研究

    Key Technology of the Absolute Gravity Measurement Under High Dynamic Environment

    • 摘要: 地球重力场信息可用于匹配导航定位,要求重力测量设备精度高、长期稳定好且适应动态测量。当前量子动态绝对重力仪延续了经典动态相对重力仪技术方案——“重力传感器+姿态控制平台”组合的方案。这从多方面限制了量子动态绝对重力仪的动态适应性和测量精度的发展,制约其在车辆、无人机、无人船等剧烈动态场景下重力测量能力。梳理了当前量子绝对重力高动态测量相关关键技术发展现状,分析探讨了其应用前景,总结了其发展方向。

       

      Abstract: Information on the Earth's gravitational field can be used for matching navigation and positioning. It requires the gravity measurement have high precision, excellent long-term stability, and adaptability to dynamic measurement. Current quantum dynamic absolute gravimeters inherit the technical scheme of classical dynamic relative gravimeters, the combination of a gravity sensor and an attitude control platform. This limits the development of quantum dynamic absolute gravimeters in terms of dynamic adaptability and measurement precision in multiple aspects, and restricts its capability under high dynamic scenarios such as vehicles, unmanned aerial vehicles, and unmanned ships. This paper will sort out the current development status of key technologies related to quantum absolute high dynamics gravity measurement, analyze the discuss their application prospects, and summarize their development directions.
