The satellite will be placed in a 636 km polar sun synchronous orbit (SSO), with an inclination of 97.957 deg. The mission life of the satellite is five years.”

According to the space agency, the primary goal of HysIS is to study the earth’s surface in visible, near infrared and shortwave infrared regions of the electromagnetic spectrum.

The co-passengers of HysIS include one Micro and 29 Nano satellites from eight different countries, the agency said, adding, all these satellites will be placed in a 504 km orbit by PSLV-C43.
