In response to the devastating terrorist attack in Jammu and Kashmir's Pahalgam that claimed the lives of 26 individuals, the Indian government and its scientific community are ramping up efforts to enhance national security. The Indian Space Research Organisation (ISRO) is preparing to launch an advanced radar imaging satellite designed to bolster surveillance along India’s sensitive borders. This urgent step is aimed at preventing future attacks by enabling constant monitoring of enemy movements, even in themost challenging weather and lighting conditions.

Radar Imaging Satellite to Strengthen Border Surveillance

ISRO is on the verge of launching a new Earth Observation Satellite, EOS-09, aboard its trusted workhorse, the PSLV-C61 rocket. What sets this satellite apart is its cutting-edge radar imaging technology. Unlike optical satellites that depend on sunlight and clear skies to capture images, EOS-09 is equipped with a synthetic aperture radar (SAR) operating in the C-band frequency. This allows the satellite to capture high-resolution images of the Earth’s surface in all weather conditions and during both day and night.

According to Union Minister for Science and Technology, Dr. Jitendra Singh, the EOS-09 satellite will significantly enhance India’s ability to conduct round-the-clock surveillance. Its radar imaging capabilities will enable it to detect even well-camouflaged assets, giving India an edge in detecting and thwarting any nefarious activities along its borders.

A Technological Leap in India’s Spy Satellite Capabilities

The addition of EOS-09 to India’s satellite fleet marks a major milestone in indigenous space technology. Indian scientists have developed this state-of-the-art satellite as part of a broader push to build self-reliance in strategic areas. The satellite will join an existing constellation of over 50 Indian satellites currently operational in space, each playing a key role in communication, navigation, weather forecasting, and surveillance.

Although India’s Cartosat-3 satellite already offers high-resolution images with a precision of less than half a meter, it remains limited by its optical system, which fails in low-light or nighttime conditions. Enemy forces have often taken advantage of these dark windows to shift troops and equipment under the cover of night. EOS-09 aims to eliminate this vulnerability by ensuring 24/7 monitoring, regardless of weather or lighting.

ISRO Launch in 'Campaign Mode'

ISRO Chairman Dr. V Narayanan confirmed that the preparations for the upcoming PSLV-C61 mission are progressing in “campaign mode,” indicating the urgency and strategic priority of this launch. The space agency is working tirelessly to ensure the radar satellite is deployed in orbit as soon as possible. This rapid pace of operations underscores the government's commitment to reinforcing national defense infrastructure through space-based technology.

Given the current security climate, the launch of EOS-09 is not just a technological achievement but also a crucial strategic step. It demonstrates India’s readiness to leverage space-based assets for internal and external security, especially in regions prone to cross-border infiltration and terrorist activity.

A New Era of Constant Vigilance

The launch of EOS-09 represents more than just another satellite in orbit—it marks the beginning of a new era of vigilance for India. By eliminating the limitations of previous surveillance tools, this radar imaging satellite ensures that potential threats can no longer hide under the cloak of darkness or bad weather. With this technological advancement, India is taking a significant stride toward maintaining round-the-clock situational awareness along its borders.

As the countdown begins for the PSLV-C61 mission, ISRO’s efforts underline how science and technology can directly contribute to national security and strategic readiness in times of crisis.
