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.
