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 was planned to be launched on 20 February 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 meant to be launched from Satish Dhawan Space Centre on 20 February 2026. It will be launched aboard a GSLV Mk II rocket, aboard the GSLV-F17 mission.
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 m 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
