EOS series GISAT series

EOS-05 (also known as GISAT-1A) is an Earth observation satellite, which is the second satellite in the GISAT series made by ISRO. It is planned to be launched in 2026 using a GSLV Mk II rocket from Satish Dhawan Space Centre. The satellite aims to improve the existing remote sensing capabilities.

Launch

GISAT-1A was planned to be launched from Satish Dhawan Space Centre between 20 February and 5 March 2026. It is now planned to be launched aboard the GSLV-F18 mission in July 2026.

Payload

GISATs will image in multi-spectral and hyper-spectral bands to provide near real-time pictures of large areas of the country, under cloud-free conditions, at frequent intervals which is, selected field image in every 5 minutes and entire Indian landmass image every 30 minutes at 42 metres (138 ft) spatial resolution.

Features of GISAT-1A are:

• 700 mm Ritchey–Chrétien telescope based on the design of Cartosat-2A
• Array detectors in Visible and Near-InfraRed (VNIR), and Short Wave-InfraRed (SWIR) bands
• Electronically steerable, phased array antenna
• High agility, jitter-free platform
