Chennai, Feb 11 (Reporter) The Indian Space Research Organisation (ISRO) has successfully completed validation of network operations of Gaganyaan Orbital Module communications systems with the European Space Agency (ESA) Ground Station by conducting a series of Radio Frequency Compatibility Tests (RFCT). These tests are essential towards ensuring readiness of the entire communications architecture and validation of compatibility of ISRO’s systems with external ground stations before undertaking Gaganyaan missions, the Indian Space Agency said on Tuesday. This requires integrated operation of the Gaganyaan onboard Telemetry, Tracking and Command (TTC), Data Handling, Audio/Video Systems with the external Ground Station. With the successful accomplishment of these RFCT jointly with ESA, end-to-end compatibility between ISRO’s Gaganyaan Orbital Module communications systems and ESA’s Ground station network has been demonstrated. Ensuring seamless communication between Mission Control Centre and Gaganyaan Orbital Module is vital for the mission success, the Indian Space Agency said. This is essential for successful accomplishment of mission operations in human space missions such as communication with onboard Crew, monitoring of various onboard systems of the Orbital Module as well as commanding operations by a team of ground based Flight Controllers. In order to provide maximal communication coverage during the Gaganyaan missions, ISRO will be utilising is own capabilities as well as external ground station support from other agencies across the world. This cooperative activity was enabled through a Technical Implementing Plan (TIP) for providing Ground Tracking Support for Gaganyaan Missions signed by both ISRO and ESA in December 2024...////...
