成功大學的電漿與太空中心已經研發磁阻式磁力計(magneto-resistive magnetometer)，磁阻式磁力計系統是由非同向性磁阻式探測器組成。磁阻式磁力計具有較小的體積(25 mm × 20 mm × 15 mm)，重量為25公克，和較低的功率消耗(120mW)。此磁阻磁力計系統將和磁通門磁強計(fluxgate magnetometer)、拉繆爾探針(Langmuir probe)、離子能量分析器(ion energy analyzer)、中性粒子分析儀(neutral particle analyzer)、太陽方位探測器(sun aspect sensor)等酬載一起搭載在探空火箭上，執行國家太空中心贊助的電離層觀測實驗計畫。
在這篇論文裡,會提到非同向性的磁阻式探測器的原理，磁阻式磁力計的系統架構，運用磁通門磁強計來校正磁阻磁力計系統，還有磁阻磁力計的溫度測試結果。此外，磁阻磁力計的建構是為了量測低頻的微小磁場變化以及直流磁場，此次探空火箭的量測結果可以提供在地球低緯度的電離層磁場資料。

The magneto-resistive magnetometer (MRM) has been developed at the Plasma and Space Science Center of National Cheng Kung University. The MRM is made of anisotropic magneto-resistive (AMR) sensor chips, which have appealing features of small size (25 mm × 20 mm × 15 mm), light weight (25 grams) and low power consumption (120 mW). The MRM and a fluxgate magnetometer, a Langmuir probe, an ion energy analyzer, a neutral particle analyzer, and a sun aspect sensor will be deployed in the Sounding Rocket Experiment #10 mission, which is supported by National Space Organization of Taiwan.
In this thesis we present the operating principle of anisotropic magnetoresistive sensor, the design of the MRM system, the calibration of MRM with the fluxgate magnetometer, and the temperature test of the MRM. The MRM system is designed to measure small variations of low frequency and DC magnetic field thus providing additional information on the Earth’s ionosphere at low latitudes.
