HRSAT 1A, 1B, 1C

HRSAT (High Resolution Satellite) 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 HRSAT carries a panchromatic and multispectral imager (four bands). The visible bands have a 2-m ground sample distance (GSD) and the infrared band has a 4-m GSD. 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 were to be launched by a single PSLV into a 660 km Polar Sun Synchronous orbit in February 2019, but were delayed to late 2023. The current status of the mission is unclear.
