The Ground Station Engineering Division (OPS-GS) of the Ground Systems Engineering and Innovation Department (OPS-G) is pleased to announce the 10th ESA International Workshop on Tracking, Telemetry and Command Systems for Space Applications, TTC2025, which will be held from the 25th to the 28th November 2025 at the European Space Operations Centre (ESOC) in Darmstadt (Germany).

Tracking, Telemetry, and Command (TT&C) are a fundamental element of space programs. Advances over the past decade in telecommunications, signal processing, computing, and electronics have significantly enhanced the design and functionality of TT&C and payload systems for both space and ground systems. The adoption of new frequency bands, including optical links, has transitioned from conceptual to operational reality. The standardization of modern modulation and coding schemes enhances the efficiency of link resource utilization. Efforts focus on achieving a combination of higher data rates, enabling greater scientific return, and optimizing ground station capacity to support the growing number of missions. At the same time, measures to enhance the security of these systems are being continuously reinforced.
