Satellite Laser Ranging system operation, at SEJONG 363115.6N 1271810.5E	UNL	Research laser operation using a Satellite Laser Ranging system for determining the precise orbits of satellites passing over SOUTH KOREA. Horizontal scan range : BTN 000 DEG and 360 DEG Vertical scan range : BTN 023 DEG and 087 DEG Satellite Laser Ranging : ND:YAG Wave length : 532 NM Max energy per pulse : 2.85 mJ Max repetition rate(frequency) : 2000 Hz Pulse width : 50 ps @ 532 NM Beam divergence angle : 5 -200 arcsec The Laser Hazard Reduction System (LHRS) : The installed LHRS provides a means of detecting aircraft before they intersect a transmitted laser beam. Upon detecting an aircraft by the radar, the LHRS provides a signal so that laser beam be blocked to transmit.
