Indian Satellite AFR Captures Images of International Space Station

An Indian-built satellite, known as AFR, has successfully captured images of the International Space Station (ISS) while in orbit. The satellite, operated by Azista Space, recorded this remarkable feat from distances of approximately 250 km and 300 km, demonstrating its advanced imaging capabilities.

The 80 kg AFR satellite was launched in 2023 and is equipped with a sensor specifically designed to track the ISS. In total, the satellite captured the ISS in five distinct frames during sunlit conditions, achieving 100 percent success in two independent imaging attempts. The resulting images boast a sampling resolution of approximately 2.2 metres, validating Azista Space’s tracking algorithms and imaging precision.

“This achievement marks a pivotal milestone for Azista and a significant leap in India’s sovereign space preparedness,” stated Srinivas Reddy, Managing Director of Azista Space. He noted that AFR is the only Indian-built satellite to achieve such a feat, enhancing the country’s capabilities in non-Earth imaging (NEI) and space situational awareness (SSA).

Significance of Non-Earth Imaging

The images from the AFR satellite reveal the core structure of the ISS, providing critical insights into space situational awareness. This capability is particularly vital for military applications, as highlighted by Bharath Simha Reddy, Assistant General Manager at Azista Space. He emphasized that non-Earth imaging is crucial for determining the location of enemy satellites.

Azista Space has established a reputation for its strong capabilities in electro-optical payloads, image processing, and satellite bus engineering. This expertise allows the company to design and deliver end-to-end SSA satellites tailored to specific customer missions. The development of indigenous algorithms has been a key contributor to the satellite’s success in capturing these images.

Future Directions and Investments

The AFR satellite, initially launched as a technology demonstrator, has begun generating revenue through the acquisition of extensive ocean imagery, covering areas about 70 km wide and 7,000–10,000 km long. Clients both in India and internationally are purchasing these images, further establishing Azista Space’s presence in the global market.

In a strategic move to bolster India’s space capabilities, Azista Space plans to invest Rs 500 crore in setting up a space-grade electro-optical payload manufacturing facility in Sanand, Gujarat. This facility aims to support India’s burgeoning space and defence needs, enhancing the nation’s sovereign capabilities in military-grade electro-optical payloads. Reddy noted that this investment will play a critical role in national security and advanced surveillance requirements, positioning India among global leaders in this specialized domain.

The upcoming manufacturing facility is expected to significantly enhance indigenous production of advanced electro-optical systems, reducing reliance on imports while generating skilled employment opportunities. Azista Space is already exporting about 85 space subsystems to foreign customers, further solidifying its role in the international space industry.

As Azista Space continues to innovate and expand its capabilities, the success of the AFR satellite represents a noteworthy advancement in India’s space exploration efforts and technological prowess.
