Status and Progress of ARGO

Over the last few years, Korea Astronomy and Space Science Institute had prepared for introducing the SLR system in Korea. Even though we spent a lot of time to overcome the many barriers just same as other projects, we could finally start the ARGO project to make the series of SLR from this year. ARGO, new SLR systems of Korea, stands for the Accurate Ranging system for Geodetic Observation and this was the name of ship on which Jason and Argonauts voyaged to retrieve the Golden Fleece in Greek mythology. The goal of ARGO project is to make two SLR systems, one is a 40 centimeter mobile SLR system and another one is an 1 meter fixed SLR system, and to start the operation from the year 2011 and 2013 respectively. The participants of ARGO project are involved in five working groups related with the components of SLR system, for example Electro-Optics, to work more specifically. Due to their efforts including the visiting to several SLR sites in abroad, we could determined the more detailed requirements and scheduling for ARGO system. In this paper, we will give the current status and future plan of ARGO project with the context of requirements and scheduling of ARGO.
