Summary
DescriptionWettzell Laser Ranging System.jpg |
English: Wettzell Laser Ranging System (WLRS), the satellite and lunar laser ranging system of the geodetic observatory in Wettzell, Bavaria. The 75cm telescope in the dome is both used to send the laser pulses and to observe the reflected signal. The small radar dish besides the dome is used to monitor air traffic: The laser is automatically switched off when a aircraft approaches the target position of the laser.
Deutsch: Wettzell Laser Ranging System (WLRS), ein System zur Messung der Entfernung von künstlichen Erdsatelliten und des Mondes am geodätischen Observatorium Wettzell, Bayern. Das 75cm Teleskop in der Kuppel wird sowohl zum Aussenden der Laserimpulse, als auch zum Empfangen des reflektierten Signals verwendet. Die kleine Radarschüssel neben der Kuppel dient der Überwachung des Flugverkehrs: Der Laser wird automatisch abgeschaltet, wenn sich ein Flugzeug der Zielposition des Lasers nähert. |
