SLR is the abbreviation for Satellite Laser Ranging. In contrast to GNSS (Global Navigation Satellite Systems), the SLR community is a small group of institutions involved in collecting data, processing the observations, or combining and analyzing the products. These activities are coordinated by the International Laser Ranging Service (ILRS).
The principle of SLR measurements is explained here.
The AIUB is contributing to the data collection with the Zimmerwald observatory and processing SLR measurements in the frame of different projects. Selected results are introduced on the subsequent pages:
