卫星地面磁测量是卫星环境试验的一个重要组成部分,精确的磁测量必须磁场或可控磁场中做。在没有大型磁设备的情况下,提出在地磁场中做磁测量题。本文分析了在地磁场中做磁测量的特点和影响测量精度的因素,指出了在场中做磁测量的应用范围,测量方法及在测量中应注意的问题,给出了在地磁做磁矩测量的几个试验测量结果。 Satellite ground magnetic measurement is an important part of satellite environmental testing. Precise magnetic measurements must be made in a magnetic field or a controlled magnetic field. In the absence of large-scale magnetic equipment, proposed in the magnetic field to do magnetic measurement problems. This paper analyzes the characteristics of magnetic measurement in geomagnetic field and the factors that affect the accuracy of measurement. It points out the application range, measurement methods and problems that should be paid attention to in magnetic field measurement in the field. Several experimental measurements.
