中低軌道地磁動(dòng)態(tài)模擬器

Dynamic Geomagnetic Field Simulator on MEO/LEO

  • 摘要: 文章介紹了1臺(tái)能為中低軌道飛行器提供動(dòng)態(tài)地磁場(chǎng)環(huán)境的模擬器，詳細(xì)論述了模擬器的系統(tǒng)組成、線圈結(jié)構(gòu)、電源和磁強(qiáng)計(jì)指標(biāo)參數(shù)、控制方式和調(diào)試方法，介紹了根據(jù)WMM2000地磁場(chǎng)模型計(jì)算出軌道上各點(diǎn)的磁場(chǎng)值，利用數(shù)值分析的方法找出輸出電流與產(chǎn)生磁場(chǎng)大小的對(duì)應(yīng)表達(dá)式，從而根據(jù)計(jì)算出的磁場(chǎng)值和輸出電流，用程控電源成功實(shí)現(xiàn)了中低軌道地磁場(chǎng)的動(dòng)態(tài)模擬。

     

    Abstract: A simulator which can provide a dynamic geomagnetic environment for spacecraft on MEO/LEO is introduced, and its system make-up, the structure of the coil, parameters of the magnetometer and power supply, controlling and debugging methods are discussed. The magnetic fields on orbit are calculated according to WMM2000 geomagnetic field model, and the expression for magnetic and current is obtained with numerical analysis. The geomagnetic field on MEO/LEO is simulated dynamically using the programmed power supply.
