Key Technology of the Absolute Gravity Measurement Under High Dynamic Environment

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.
