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 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

GISAT-1A will 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. ^{[4] [5] [6]}

Payload

GISAT-1A in deployed configuration.

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

Imaging capabilities of GISAT-1A

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
