Eyes In the Sky: How India's Satellite Fleet Is Leading The Charge In National Defence
Last Updated: India has built one of the largest remote-sensing satellite networks ramping up with the launch of its first radar imaging satellite RISAT-1 in 2009 post the 2008 Mumbai attacks. With the Army on the ground, the Navy at sea, and pilots in the air, India boasts of one of the largest and formidable defence forces in the world. Now it's the country's rapidly-advancing satellite coverage that bolsters its border surveillance, day and night, under all weather conditions, becoming a backbone for strategic defence. 'At least 10 satellites are continuously working round-the-clock for the strategic purpose to ensure the safety and security of the citizens of the country. We have to monitor our 7,000 km seashore areas and the entire Northern part continuously. Without satellite and drone technology, we can't achieve that," said Dr V Narayanan, ISRO chairman last week in Imphal. With the IRS series, Cartosat, Oceansat, Resourcesat, and RISAT (Radar Imaging Satellites), India has built one of the largest constellations of remote sensing satellites in operation providing images with different spatial, spectral, and temporal resolutions to meet different users. The recent tensions with neighbouring Pakistan highlighted significant capabilities of this network. 'Our existing capabilities are very good, and have become more robust with the launch of radar imaging satellites (RISAT series). If we look at the pictures from Operation Sindoor, the pictures showing clear damage to air fields – whether taken by satellites or UAVs – were very clear. We need to keep strengthening our constellation further to ensure continuous, 24X7 surveillance round the clock," said Ajay Lele, Deputy Director General, MP-IDSA, New Delhi. ADVANCED RADAR IMAGING SATELLITES ISRO's launch of the first radar imaging satellite in 2009 post the 2008 Mumbai attacks provided a shot in the arm, delivering 24-hour imagery under all-weather data, day and night enhancing border surveillance for 13 years, until its re-entry in 2022. Since then, it has launched RISAT-1A in 2012, and RISAT-2BR1 in 2019 each carrying a mission life of five years. The latest launch of EOS-09, which could not be accomplished, would have further strengthened these capabilities, injecting one more Radar Imaging Satellite (RISAT-1B) into space. Since most of these satellites are in polar, sun-synchronous orbits, they provide consistent coverage by revisiting the same location, at the same local time each day. EYE ON THE BORDERS, DAY AND NIGHT SURVEILLANCE The Synthetic Aperture Radar on these satellites plays a crucial role in strategic defence as it provides high-resolution data, day and night under all-weather conditions. In spotlight mode, the radar signal can be focussed on a specific area to capture high-resolution images especially critical for military installations and infrastructure. The longer the time that radar spends over a target, the better the resolution. Multiple radar pulses create a more detailed image. Since most of these satellites have dual purpose, they serve critical strategic needs, and at the same time, provide useful data for various other sectors. While the high-resolution imagery is only shared with government and military users, the images for mapping agriculture, urban planning, water resources, landslides, glaciers, ground water potential, disaster management, forest biomass estimation continue to be used for multiple other applications. India's capabilities will get a major boost with the much-anticipated launch of NISAR-NASA-ISRO Synthetic Aperture Radar in June-July this year – which will offer unprecedented view of the Earth, mapping the entire globe with precision every 12 days, and capture places that have otherwise been obscured. The satellite will be able to detect changes as small as 10 m, piercing through dense cloud dover, day and night. First Published:

RISAT-1B Satellite: India's answer to Pahalgam's tragedy
India's space prowess is set to soar with the Indian Space Research Organisation (ISRO) launching RISAT-1B, also called EOS-09, on May 18, 2025, from the Satish Dhawan Space Centre in Sriharikota. This radar imaging satellite, the seventh in the RISAT series, comes days after a deadly terrorist attack in Pahalgam, making its role in national security vital. Launched aboard the Polar Satellite Launch Vehicle (PSLV-C61) XL at 6:59 am IST, the 1,710 kg RISAT-1B will orbit at 529 km in a sun-synchronous path, equipped with C-band synthetic aperture radar (SAR) for all-weather surveillance. As India strengthens its borders post-Pahalgam, this satellite promises to be a game-changer. Let's explore the RISAT series' evolution and how RISAT-1B fits into this legacy. The RISAT Series: A Shield in the Sky The RISAT (Radar Imaging Satellite) series began as a response to India's security needs, particularly after the 2008 Mumbai attacks. Designed for dual civilian and military use, these satellites use SAR to capture high-resolution images, unaffected by weather or time of day. The series includes RISAT-2, RISAT-1, RISAT-1A, RISAT-2B, RISAT-2BR1, and RISAT-2BR2, each advancing India's ability to monitor borders and counter threats. RISAT-1B's launch marks another milestone in this journey. Evolution of the RISAT Series Each RISAT satellite has brought technological leaps, enhancing India's surveillance capabilities. Here's a look at their development: – RISAT-2 (2009): Launched in April 2009, RISAT-2 was India's first dedicated radar imaging satellite, developed with Israel's assistance. Weighing 300 kg, it used an X-band SAR with a resolution of about 1 meter. Deployed post-Mumbai attacks, it focused on border surveillance, helping security forces track infiltration. Its compact design and agility made it a vital asset for early counter-terrorism efforts. – RISAT-1 (2012): Launched in April 2012, RISAT-1 was India's first indigenously developed SAR satellite. Operating in C-band, it offered resolutions from 1 to 50 meters, suitable for both civilian (agriculture, disaster management) and military purposes. At 1,858 kg, it was heavier, orbiting at 536 km. Its versatility allowed monitoring of terrorist hideouts and border activities, laying the foundation for future RISATs. – RISAT-1A (2022) : Also known as EOS-04, RISAT-1A was launched in February 2022. A follow-on to RISAT-1, it used C-band SAR with improved imaging capabilities. Weighing 1,852 kg, it orbited at 529 km, enhancing border surveillance and disaster monitoring. Its advanced data processing supported real-time intelligence, crucial for operations like the 2016 surgical strikes. – RISAT-2B (2019): Launched in May 2019, RISAT-2B marked a shift to the RISAT-2 series' upgrades. Using X-band SAR, it achieved a finer resolution of about 0.5 meters. Weighing 615 kg, it orbited at 557 km, focusing on military surveillance. Its enhanced imaging helped identify small objects, aiding counter-terrorism missions. – RISAT-2BR1 (2019): Launched in December 2019, RISAT-2BR1 pushed boundaries with a resolution of 0.35 meters, among the finest in the series. Its 628 kg frame carried an advanced X-band SAR, orbiting at 576 km. This satellite played a key role in tracking cross-border threats, offering crystal-clear images for security operations – RISAT-2BR2 (Proposed/Assumed): While limited details are available, RISAT-2BR2 is part of the series' ongoing enhancements. Likely similar to RISAT-2BR1, it uses X-band SAR with high-resolution imaging, further strengthening India's surveillance network. RISAT-1B: A Timely Addition RISAT-1B, with its C-band SAR, builds on RISAT-1 and RISAT-1A's legacy. Its 1,710 kg frame and 529 km orbit ensure comprehensive coverage of India's landmass. Key features include: – All-Weather Imaging: Unaffected by clouds or darkness, it ensures constant monitoring. – High-Resolution Surveillance: Capable of detecting small objects, critical for identifying terrorist movements. – Dual-Use Capability: Supports civilian tasks like agriculture and disaster management alongside military operations. Post-Pahalgam, RISAT-1B's launch aligns with Operation Sindoor, enhancing India's ability to monitor terrorist activities. Its data will support swift responses, preventing infiltration and ensuring national safety. The Road Ahead: NISAR and Beyond ISRO isn't stopping here. In June 2025, the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite will launch aboard the Geosynchronous Satellite Launch Vehicle (GSLV-F16). This joint India-US project will use dual L-band and S-band SAR for global monitoring, with applications in climate, agriculture, and security. NISAR's advanced imaging will complement the RISAT series, creating a robust surveillance network. Why RISAT-1B Matters The Pahalgam attack underscored the need for vigilant border monitoring. RISAT-1B, with its cutting-edge technology, strengthens India's skyward defence. The RISAT series has evolved from RISAT-2's basic imaging to RISAT-2BR1's pinpoint accuracy, and RISAT-1B continues this trend. Its ability to provide real-time, weather-proof intelligence will deter cross-border threats, building on successes like the 2016 surgical strikes. As India prepares for NISAR, the RISAT series remains a cornerstone of its security strategy, ensuring the nation stays one step ahead of its adversaries. In a world of evolving threats, RISAT-1B is more than a satellite—it's a symbol of India's resolve to protect its borders, inspired by tragedies like Pahalgam. With ISRO's relentless innovation, the skies are not just a frontier but a shield for the nation.
