The satellite laser ranging system for the satellite laser ranging (SLR) observations in the Shimosato Hydrographic Observatory (SHO) has been in operation for almost 10 years since its last update in 2009. In order to enhance the safety and usability of the observation system, the SHO updated the laser ranging equipment in 2018. The new system uses a laser oscillator with a changeable pulse repetition rate up to 1 kHz (i.e., kilohertz laser), by which we can collect the ranging data at a higher rate than by the former one with a pulse repetition rate of 5 Hz. The relevant updates on the control devices and software contribute to the simplification of the SLR operation. These updates will enable the SHO to continue to provide highquality laser ranging data to the International Laser Ranging Service(ILRS) as a Global Geodetic Observing System (GGOS) site.Journal
