The Indian Space Research Organisation (ISRO) is preparing to launch the GSLV-F17 mission carrying the GISAT-1A satellite, also designated EOS-05, towards the end of May 2026 from the Satish Dhawan Space Centre at Sriharikota. The GISAT-1A is a geo-imaging Earth observation satellite weighing approximately 2,100 kilograms that will operate from a geostationary orbit. Unlike satellites in low Earth orbit that pass over a region only periodically, a satellite stationed in geostationary orbit can provide near-continuous observation of the Indian subcontinent. This makes GISAT-1A particularly valuable for rapid monitoring of natural hazards and disasters such as floods, cyclones and landslides, where timely imagery is critical for response. The satellite is designed to deliver high-resolution multi-spectral and hyper-spectral images, enabling monitoring of agriculture, forestry, water resources, urban development and natural disasters. The launch vehicle is the Geosynchronous Satellite Launch Vehicle Mark II (GSLV Mk II), the largest operational launch vehicle developed by India. It is a three-stage vehicle with four liquid strap-on motors, and its third stage uses the indigenously developed and flight-proven cryogenic Upper Stage (CUS). The mission follows a stage-3 failure of the PSLV-C62 in ISRO's first launch of 2026 in January, making a successful GSLV-F17 flight an important confidence-building milestone. The geo-imaging capability significantly strengthens India's disaster management, agriculture planning and resource monitoring infrastructure, contributing to the country's space-based governance and early-warning ecosystem.
