ISRO’S use of the high throughput X-band frequency for the Aditya mission is a first.

World News

ISRO had previously solely utilized X-band for payload data downloads. X band operates at 8–8.5GHz compared to S-band’s 2-2.5GHz frequency. This complies with universal requirements for missions outside the influence of Earth.

The main benefit of using X-band is that it makes it possible to communicate with faraway satellites more clearly.

The distance in the instance of Aditya-L1 is 1.5 million kilometers.

The first Earth-bound manoeuvre of Aditya-L1 was accomplished, and ISRO declared, “The satellite is healthy and performing normally. The second Earth-bound manoeuvre is set for 3am on September 5 and the new orbit is 245km x 22,459km.

Multiple tracking stations run by the Bangalore-based ISRO Telemetry, Tracking and Command Network (ISTRAC) are responsible for managing Aditya’s operations. A temporary station is part of the setup, and TOI was the first to report on it in January. It is located in the Fiji Islands.

An 18m antenna near Byalalu, about 30 kilometers from Bangalore, serves as the primary operational antenna. The Aditya-L1 mission, which was planned to carry X-band telemetry, provided funding for the antenna setup, which was commissioned in 2021.

It has features for automatic tracking in both bands and can be controlled remotely from the network management center.
