AI Technical Summary

Technical Problem

In satellite navigation denied environments, existing heterogeneous unmanned systems suffer from large long-term cumulative drift and are susceptible to electromagnetic interference, resulting in low cooperative positioning accuracy and poor robustness.

Method used

A multi-source quantum sensing fusion method is adopted. An absolute time synchronization benchmark is established by deploying CPT chip atomic clocks on UAV and unmanned vehicle nodes. Absolute attitude changes are measured by using NV color center quantum gyroscopes. A quantum entanglement distribution link is established for interferometric measurement. The error state Kalman filter algorithm is combined to perform multi-source information fusion estimation and output the absolute pose state.

Benefits of technology

It achieves high-precision and robust cooperative positioning of heterogeneous unmanned systems in satellite navigation denied environments, eliminates drift interference from traditional sensors, and provides picosecond-level timestamp alignment and nanometer-radian-level attitude perception accuracy.

Abstract

本发明涉及异构无人系统协同定位技术领域,具体涉及一种基于多源量子传感融合的异构无人系统协同定位方法,该方法通过在节点上部署CPT芯片原子钟进行双向时间比对,建立绝对时间同步基准;部署NV色心量子陀螺仪测量载体旋转诱导的Berry相位,获取绝对姿态变化信息;在节点间建立量子纠缠分发链路进行干涉测量,获取节点间高精度的相对距离与相对姿态;最后以绝对时间同步基准为时间戳对齐基础,将绝对姿态变化作为状态预测输入,将相对距离与姿态作为观测约束输入,通过误差状态卡尔曼滤波算法进行误差闭环修正,输出绝对位姿状态。本发明有效克服了卫星导航拒止及强干扰环境下传统传感器漂移发散的缺陷,实现了高鲁棒性的三维协同定位。
