Talking to TOI, Isro chairman K Sivan said, "We are going to launch HySIS at 9.59 am on November 29 from Sriharikota. Over 30 foreign satellites, including nano and mini satellites, will also be launched along with the main payload. Out of the 30 commercial satellites, 23 are from the US."
The satellite, which can see in 55 spectral or colour bands from 630 km above the ground, will be used for a range of applications like agriculture, forestry and assessment of coastal zones, inland waters, soil and other geological environments. Being an earth observation satellite, HySIS will also be used by the military for surveillance purpose. The optical imaging detector array chip in the HySIS satellite has been designed by Isro's Ahmedabad-based Space Applications Centre and manufactured by its electronic arm, Semi-Conductor Laboratory, Chandigarh.The hyspex technology is still an evolving science and has become a new global trend. Hyperspectral imaging combines the power of digital imaging and spectroscopy. It collects and processes information from across the electromagnetic spectrum. Hyspex imaging enables distinct identification of objects, material or processes on the Earth by reading the spectrum for each pixel of a scene from space.
HySIS carries two payloads in visible and near infrared regions of the electromagnetic spectrum. This earth observing imaging spectrometer will operate in the 0.4 to 0.95µm spectral range, will have 55 spectral bands with 10 nanometre spectral sampling and 30 metre spatial sampling. Push-broom scanning mode is the operating mode of this sensor from a 630-km orbit. According to Isro officials, 1000 X 66 pixels were designed to be readout, from both top and bottom directions, using four analog video ports to meet the frame rate requirement.
Metal strapping was used for swiftly transferring integrated charges from image to storage region, in order to reduce image smear. Designs (both at chip and package levels) went through detailed review, before clearing for mask making and package fabrication, by a team consisting of members from Isro's SCL (Semiconductor Laboratory) and SAC (Satellite Application Centre).HySIS spacecrafts carries the Hyper Spectral Compact Imaging in VNIR (Visible and Near Infrared) and SWIR (Shortwave Infrared) spatial region in 60 and 256 contiguous spectral bands respectively, with 10 nm bandwidth providing 30m spatial resolution and covering a swath of 30 km at 630 km orbit.
According to the previous and latest mission kits it appears that C43 is the first flight of the Higher Performance HPS3 stage which replaces the standard PS3 stage as part of the overall PSLV Higher Performance Project (PSLV-HP).

The High Performance PS3 (HPS3) has been around since PSLV C4/METSAT mission back in 2002. https://www.isro.gov.in/sites/default/files/flipping_book/PSLV-C4/HTML/files/assets/basic-html/page-1.htmlhttps://www.isro.gov.in/50th-high-performance-motor-case-hps3-third-stage-of-pslv-realised
