HRSAT 1A, 1B, 1C

HRSAT is an Indian satellite constellation consisting of three satellites in a single orbital plane.

A constellation of small satellites with sub meter resolution in PAN and a daily revisit capability has a great potential for commercial applications in large scale mapping, agriculture, urban planning, rural development, infrastructure development, Disaster management, etc.

The constellation will have daily revisit capability with 45 tilts. The payloads will have imaging capability of ~1 m Ground Sampling Distance (GSD) with 15 km swath in Panchromatic mode, 2 m / 4 m GSD in three band multi-spectral (Mx) mode with 15 km swath, and 20 m GSD in IR band with a swath of 6 km.

The three satellites are to be launched by a single PSLV into a 660 km Polar Sun Synchronous orbit in February 2019.
