Abstract
The Transportable Adaptive Optical Ground Station, which was located at Tenerife (Spain) from 2014 until 2019 was shipped for a refurbishment and several enhancements to Switzerland. Following the refurbishment, a measurement campaign at the Swiss Optical Ground Station and Geodynamics Observatory Zimmerwald (Switzerland) was performed, in July/August 2021. The optical counter terminal for the experiments was the TDP1-LCT at the geostationary Alphasat satellite. In the seven weeks of the campaign, measurements for optical uplink communication at a rural site in Europe at an altitude of 900 meters to a GEO spacecraft were gathered. We give an overview of the improvements of the T-AOGS and the actual status after the refurbishment. We present the results of the link activities, e.g. the uplink budget (ground to space) and the dynamic of the atmosphere (scintillations index, number of fades, fade duration).
