The invention discloses an unmanned aerial vehicle magnetic field vector measurement precision system which is composed of an aerial carrier system, an aeromagnetic three-component magnetometer and an accessory, can accurately measure a vertical gradient and an oblique gradient perpendicular to a measuring line respectively, and can measure magnetic three-component data and magnetic gradient data in a certain direction at the same time. The method does not need the conversion calculation of conventional total intensity magnetic anomaly for secondary calculation, can avoid errors possibly introduced in the conversion process, is ingenious in design and reasonable in structure, magnetic anomaly three-component data is only related to field source magnetic parameters such as the total magnetization intensity direction, direction information of a normal field does not need to be considered in the application process, and the method is suitable for large-scale popularization and application. The method is slightly influenced by the position of a research area (such as a low-latitude area), and has better description capability theoretically for the condition with more complex geological conditions.
本发明公开了一种无人机磁场矢量测量精度系统,由载机系统,航磁三分量磁力仪和附件三大部分构成,可分别精确测定垂向梯度和垂直于测线的斜向梯度,可同时测量磁三分量数据及某方位磁梯度数据,不再需要常规总强度磁异常的转换计算来二次求取,可避免该转换过程中可能引入的误差,且设计巧妙,结构合理,磁异常三分量数据仅仅与场源磁性参数如总磁化强度方向相关,应用过程中无需考虑正常场的方向信息,受研究区域位置(如低纬度地区)影响小、对能地质条件更复杂的情况理论上也具有更好的描述能力。
