Abstract

One of the important ways to improve the performance of magnetometers in satellite exploration is to reduce magnetic noise from satellites. One of the methods to decrease magnetic noise is by extending the satellite boom. However, this approach is often not preferred due to its high cost and operational considerations. Therefore, in many cases, removing interference from the satellite platform in the measured dataset is widely utilized after data acquisition. In this study, we would like to introduce an algorithm for removing magnetic noise observed from magnetometers installed on two solar panels and one main body without a boom.

위성에서 나오는 자기잡음(magnetic noise)을 줄이는 것은 위성탐사에서 자력계의 성능을 향상시키는 중요한 방법 중의 하나이다. 자기잡음(magnetic noise)를 줄이는 방법 중의 하나가 위성에서 붐(boom)을 길게 뽑아내는 것이나, 이것은 높은 비용과 위성 운용 난이도 측면에서 선호하지 않는 방법이다. 그래서 많은 경우, 자기장 데이터 산출 후에 측정 데이터 세트에서 위성 플랫폼의 자기 간섭을 제거하는 것이 널리 사용된다. 본 연구에서는 붐 없이 태양전지판에 2개 그리고 본체 1개씩 각각 설치된 자력계(magnetometer)에서 관측한 자기잡음(magnetic noise)을 제거하는 알고리즘을 소개하고자 한다.
