Abstract

Korea Astronomy and Space Science Institute (KASI) has been operating SLR (Satellite Laser Ranging) system with 2kHz repetition rate for satellite precise orbit and spin determination as well as space geodesy. But the SLR system was improved to be capable of laser ranging with high repetition rate, up to 10kHz by developing new operation software and novel range gate generator, called HSLR-10. The HSLR-10 will contribute to the accurate spin rate determination of geodetic satellites and geodetic research due to its largest repetition rate in the world. In this study, the development methodology and configuration of operation software are addressed, and its validation results are also presented.

한국천문연구원은 인공위성 정밀궤도 결정, 우주측지 및 인공위성 자세역학 연구를 위해서 2kHz 반복율을 가지는 SLR 시스템을 운영하고 있다. 그러나 측지위성의 회전속도를 보다 정밀히 결정하고 거리 측정 정밀도 향상을 위해서 고반복율의 SLR 관측 데이터가 요구된다. 따라서 고반복율 시스템 구현을 위해 운영 소프트웨어 및 레인지 게이트 생성기를 개발하여 최대 10kHz 반복율로 레이저추적이 가능한 HSLR-10(High repetition-rate Satellite Laser Ranging-10kHz) 시스템으로 개선하였다. 본 연구에서는 10kHz 반복율을 가지는 HSLR-10 시스템의 운영 소프트웨어 개발 방법, 구성 및 검증 결과를 제시한다.
