India’s New Eye in the Sky: EOS-05 Satellite and What It Means for South Asia

EOS-05 is a single satellite that is part of a broader imitative of India to strengthen its ISR capabilities.

The Indian Space Research Organization (ISRO) recently launched a new surveillance satellite designated as EOS-05 into geosynchronous earth orbit (GEO). The launch was carried out with the GSLV-F17 rocket.

The satellite – launched on September 4 – is the first earth observation satellite deployed in GEO by India. The satellite will allow New Delhi to continuously observe the subcontinent from an altitude ranging between 34,903 km and 35,884 km. The chairman of ISRO, V. Narayanan, said that “EOS-05 will become India’s first dedicated imaging satellite from the geo orbit providing important strategic data for the country.” 

The launch of the satellite is part of India’s long-term plan to strengthen its intelligence, surveillance, and reconnaissance (ISR) capabilities. The satellite will provide India with the capability to persistently track military movements in the subcontinent – especially Pakistan’s naval warships, aircraft, strategic assets movements, and force mobilization during crisis time. A new eye in the sky is an important military asset for India and can increase its counterforce capabilities in the age of emerging and disruptive technologies. 

India’s current space architecture consists of navigation, communication, ISR, and scientific satellites. For the purpose of communication, India has three dedicated military satellites – two of which are used by the Indian Navy and one by the Indian Air Force. Besides this, India has around 10 satellites that are dual-capable and can be used for military communication. The Indian navigation satellitessystem – known as Navigation with Indian Constellation (NavIC) – has three operational satellites, IRNSS-1B, IRNSS-1I , and NVS-01. However, for basic positioning service four satellites are required in orbit ; the next satellite NVS-03 would be launched soon. The Indian ISR architecture consists of the CROSAT series for Optical purposes, the RISAT and NISAR series for SAR purposes, and the EMISAT satellite for Electronic ISR. The newly launched EOS-05 would be India’s first ISR satellite that would give real-time persistent observation of the subcontinent. 

In 2024, India’s Cabinet Committee on Security (CCS) approved the Space Based Surveillance Phase-III (SBS-III) program that aimed to deploy 52 defense satellites into low-earth orbit (LEO) and geostationary orbit for surveillance. Under this project, ISRO will deploy 21 satellites and the private sector will develop 31 satellites. 

After the May 2025 crisis, there have been calls within the Indian strategic community to further strengthen Indian military capabilities in the space domain. For example, former Indian Chief of Defense Staff General Anil Chauhan, speaking at the Indian Defense Space Symposium (IDS) 2026, stressed the importance of military space based assets. He said, “If we fail in space, we will be forced to fight blind. However, if we dominate in space, we will fight with foresight.” 

The statement reflects a transformation in India’s strategic thinking vis-à-vis the military utility of space. The evolving character of warfare necessitates strengthening ISR architecture for maintaining persistent surveillance of strategically important areas both during peacetime and crisis situations.
