Last week, ISRO’s PSLV rocket launched the HYsIS hyper-spectral imaging satellite along with 30 secondary payloads into orbit. Below is a closer look at these payloads taken from ISRO’s mission guide.
HysIS is an earth observation satellite developed by ISRO. It is the primary satellite of the PSLV-C43 mission. The satellite is built around ISRO’s Mini Satellite-2 (IMS-2) bus and the mass of the spacecraft is about 380\kg.
The satellite was placed in 636 km polar sun synchronous orbit with an inclination of 97.957 deg. The mission life of the satellite is 5 years. The primary goal of HysIS is to study the Earth’s surface in visible, near infrared and shortwave infrared regions of the electromagnetic spectrum.
HysIS Mass Specifications
Mass: ~380 kg
Overall Size: 2.158 m x 1.386 m x 1.121 m in stowed configuration
Payload: Hyperspectral Imager in VNIR and SWIR bands
Power: 730 W, 64 Ah Li-Ion battery
The co-passengers of HysIS include 1 Micro and 29 Nano satellites from 8 different countries. The total weight of 30 co-passenger satellites is 261.5 kg. All these satellites were placed in a 504 km orbit by PSLV-C43. These satellites have been commercially contracted for launch through Antrix Corporation Limited, the commercial arm of ISRO.
