RESEARCH ON GEOMAGNETIC DIURNAL VARIATION OBSERVATION SYSTEM BASED ON SURFACE MOBILE PLATFORM AND ITS APPLICATION TO DEEP SEA SURVEY

摘要: 基于水面智能移动平台,提出了一种深远海地磁日变观测系统的设计方案及观测方法。该系统采用水面智能移动平台搭载地磁日变观测系统,自主航行至规定水域进行原位连续观测。其设计续航能力40d,可观测深度30m,采用自主动力维持海面上对地位置范围≤1000m。实验表明,该系统实际功能和性能与设计方案一致,证明了该设计及观测方法的有效性和先进性。

Abstract: A geomagnetic diurnal variation observation system for deep sea survey based on intelligent mobile platform was introduced in this paper. The system is carried by an intelligent mobile platform on the sea surface, which may automatically navigate to specific regions for continuous in-situ observation. The designed endurance of the system is 40 days, with an observable depth of 30 m, and the range of ground position on the sea surface maintained by the autonomous power is no more than 1 000 m. The experiments show that the actual function and performance of the system are consistent with the design scheme, which proves the effectiveness and advancement of the design and observation method.
