The European Space Agency operates an optical ground station at Observatorio del Teide, equipped with a 1‑m telescope and a multipurpose configuration for commissioning and testing laser communication payloads. The study investigates how atmospheric turbulence parameters affect the performance of bidirectional ground‑to‑space laser communication experiments. The authors characterize the bit‑error‑rate (BER) behavior under varying turbulence conditions by measuring BER across different atmospheric states. The satellite‑to‑ground link has yielded more than 80 successful sessions since 2001, with an average BER of 1×10⁻⁶ over 20‑minute periods and occasional BER as low as 10⁻⁹–10⁻¹⁰ over 5‑30 minute intervals.
The European Space Agency has built an optical ground station sited at the Observatorio del Teide operated by the Instituto de Astrofísica de Canarias. This station, equipped with a 1m telescope, has a multipurpose configuration for in-orbit commissioning and checkout of laser communication payloads. Since November 2001, the bidirectional link with satellite ARTEMIS has been established in more than 80 successful sessions. In this paper, we analyze the influence of turbulence parameters on the performance of communications in the bidirectional ground to space laser communication experiments. The link performance observed in the satellite-to-ground channel showed average bit error rates of 1E-6 over long durations (20 minutes), however in some occasions BER's of at least 10<sup>-9</sup> -10<sup>-10</sup> over durations of 5 to 30 minutes were observed. The behavior of the Bit Error Rate measurements performed in different turbulence conditions is characterized.
