We have designed and integrated a minimum SLR (Satellite Laser Ranging) system, named as Omni-SLR, which aims at a better global coverage of SLR network in the future. After a number of assembly tests, we could successfully receive retro-reflected signals from low-orbit satellites, i.e. SARAL, SWARM-C and BEACON-C, on 22 and 26 December 2023, at the rooftop of NIPR Tachikawa. The details of the outcome will be presented as well as the current system configuration. We plan to install the system at GSI's Ishioka Geodetic Station where our development should proceed more effectively. We also plan to test it in Antarctica Syowa Station within a few years.
