Measuring atmospheric dispersion with WLRS in multiple wavelength mode

The WLRS (Wettzell Laser Ranging System) allows the simultaneous tracking of satellites on two different wavelengths. These are the fundamental frequency of Nd:YAG at 1.064 microns and the second harmonic at 532 nm. Range measurements to the satellite LAGEOS were carried out with different experimental set-ups, after developing a detector unit based on a silicon avalanche photodiode in Geiger mode, which is sufficiently sensitive in the infrared domain. An approach towards a quantitative interpretation of the data is suggested and discussed briefly.

LLR: Activities in Wettzell

Following the idea of a fundamental station, the Wettzell Laser Ranging Station was designed to range to all types of satellites and to the moon. After obtaining the first lunar echos in October 1990, the system's operation was improved. A short report of lunar ranging activities is given.
