On December 4, 2024, the European Space Agency (ESA) and the Indian Space Research Organisation (ISRO) formalized an agreement to provide ground station support for ISRO's Gaganyaan human spaceflight program. This collaboration aims to enhance communication and tracking capabilities for the Gaganyaan missions, which include two uncrewed flights followed by a crewed mission planned for 2025.

Technical Implementing Plan (TIP)

The agreement includes a Technical Implementing Plan that outlines how ESA will assist ISRO in tracking and monitoring the Gaganyaan crew module using its global network of ground stations. This support is crucial for ensuring seamless data flow and communication during the missions.

Ground Station Support

ESA will utilize its 15-meter antenna in Kourou, French Guiana, along with additional antennas from the German Aerospace Centre (DLR) and the Spanish National Institute for Aerospace Technology (INTA). This network will facilitate real-time tracking and command capabilities throughout the missions.

Compatibility Testing

A suitcase-sized model of Gaganyaan's radio equipment is set to undergo compatibility testing at ESA's Ground Segment Reference Facility in Germany. These tests will ensure that the spacecraft's radio systems can effectively communicate with ESA's antennas, which is essential for mission success.

This agreement builds on a long history of collaboration between ISRO and ESA, which has included support for various missions such as Chandrayaan-3 and Aditya-L1. The partnership is seen as a significant step forward in international space cooperation, particularly as ISRO advances its human spaceflight capabilities through the Gaganyaan program.

ESA's involvement in supporting ISRO's Gaganyaan missions represents a critical enhancement of India's capabilities in human spaceflight, leveraging ESA's extensive experience in ground operations and communications.
