Earth observation satellite of India
From Wikipedia, the free encyclopedia
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.[1][2][3]

Launch
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
| Band | Channels | Ground Resolution(m) | Range(μm) |
|---|---|---|---|
| Multispectral (VNIR) | 6 | 42 | 0.45 – 0.875 |
| Hyperspectral (VNIR) | 158 | 318 | 0.375 – 1.0 |
| Hyperspectral (SWIR) | 256 | 191 | 0.9 – 2.5 |
