The Accurate Ranging System for Geodetic Observation – Mobile (ARGO-M) was successfully developed as the first Korean\udmobile Satellite Laser Ranging (SLR) system in 2012, and has joined in the International Laser Ranging Service (ILRS)\udtracking network, DAEdeoK (DAEK) station. The DAEK SLR station was approved as a validated station in April 2014,\udthrough the ILRS station “data validation” process. The ARGO-M system is designed to enable 2 kHz laser ranging with\udmillimeter-level precision for geodetic, remote sensing, navigation, and experimental satellites equipped with Laser Retroreflector\udArrays (LRAs). In this paper, we present the design and development of a next generation high-repetition-rate SLR\udsystem for ARGO-M. The laser ranging rate up to 10 kHz is becoming an important issue in the SLR community to improve\udranging precision. To implement high-repetition-rate SLR system, the High-repetition-rate SLR operation system (HSLR-10)\udwas designed and developed using ARGO-M Range Gate Generator (A-RGG), so as to enable laser ranging from 50 Hz to 10\udkHz. HSLR-10 includes both hardware controlling software and data post-processing software. This paper shows the design\udand development of key technologies of high-repetition-rate SLR system. The developed system was tested successfully\udat DAEK station and then moved to Sejong station, a new Korean SLR station, on July 1, 2015. HSLR-10 will begin normal\udoperations at Sejong station in the near future
