Abstract

In this paper, we proposed on the azimuth correction method for a line-of-sight data-link tracking antenna system. Tracking antenna system is essential to maintain line-of-sight between moving object and data-link equipment. In order to calculate the azimuth and elevation between the moving object and antenna system, we used GPS data. also to match the each coordinate systems, we used geomagnetic sensor or beacon. However, the geomagnetic disturbance-prone terrain in places difficult to correct calibration. The first step, finds the location of the strongest RF signal, we should remember the difference between the reference point and the detected position of the antenna. The second step, we could communicate each other. And the azimuth angle is calculated by GPS values. Despite the geomagnetic interference, we can correct the azimuth angle quickly and easily.

본 논문에서는 가시선 데이터링크용 추적안테나 시스템에 적용하기 위한 방위각 보정 알고리즘에 대해 연구한다. 이동하는 물체와 가시선 통신링크를 유지하기 위해서는 추적안테나 시스템이 필수적이다. 방위각과 고각계산을 위해서는 이동체와 안테나시스템의 GPS값을 이용하는데, 이때 두 좌표계의 동일성을 유지하기 위해서 초기에 지자기센서나 beacon등을 이용하여 보정을 하게 된다. 하지만 지형적으로 지자기교란이 생기기 쉬운 장소에서는 정확한 보정이 어렵다. 따라서 본 논문에서는 초기에 RF신호의 수신세기추적을 통해서 신호의 발생 위치를 검출하고 검출된 위치까지의 방위각 보정 값을 계산하여 통신링크개설 후 수신된 GPS값에 보정 값을 적용함으로서 주변의 영향을 최소화하면서 쉽고 빠르게 보정할 수 있다.
