Space PSU NewSpace India Limited (NSIL) is working on issuing an expression of interest (EoI) for the Small Satellite Launch Vehicle (SSLV), the latest rocket from the Indian Space Research Organization (ISRO). After selecting an industry consortium for the product ionization of ISRO’s workhorse Polar Satellite Launch Vehicle (PSLV), NSIL has begun work on issuing an EoI for the Small Satellite Launch Vehicle (SSLV) (SSLV).
The PSU was also interested in putting the GSLV MK-III into production, but that is currently only projected to happen in the future. “The SSLV will be the next step,” Radhakrishnan D, chairman and managing director of NSIL, stated. We are currently in the midst of drafting the EoI for it, whereas GSLV MK-III will be introduced at a later date.”
The SSLV was designed by the Indian Space Research Organization (ISRO) to address the demand for launch services in a cost-effective manner. This all-solid vehicle is capable of launching satellites up to 500 kg in mass into Low Earth Orbit through three stages of operation (LEO).
SSLV will be equipped with three solid propulsion stages as well as a liquid propulsion-based Velocity Trimming Module (VTM) as a terminal stage, despite the fact that it is outfitted with three solid propulsion stages.
A lift-off weight of approximately 120 tonnes is achieved with a 2-meter diameter and 34-meter length SSLV. SSLV is capable of launching satellites weighing approximately 500kg into a 500km flat orbit. “The important characteristics of SSLV are its low cost and quick turn-around time, its flexibility in supporting many satellites, its feasibility for launch on-demand, and its minimal launch infrastructure requirements,” the VSSC continues.
Following the completion of the selection of the consortium for the contract to produce five PSLVs, NSIL is currently in the process of finalizing all service-level agreements and discussing terms and conditions with the selected consortium. According to Radhakrishnan, once all of the terms and conditions have been discussed, the formal agreement will be signed.
This was the first time that the Hindustan Aeronautics Limited (HAL)-L&T consortium has been selected for the PSLV contract, which was initially reported by the Times of India.
Small Satellite Launch Vehicle
NSIL’s interest exploratory letter (IEN) on the transfer of technology for the small satellite platform — the Indian Mini Satellite-1 (IMS-1) Bus — has received positive feedback, according to Radhakrishnan. “We have received responses from more than ten different companies. We will figure out the specifics of how the technology will be transferred to these companies. “This should go place very soon,” he stated.
The Times of India was the first to report about the IEN, which occurred in mid-March when the Department of Space (DoS) authorized NSIL to transfer the technology.
In addition to offering a dedicated platform for payloads for different types of satellites, the platform will also enable low-cost access to space.
A small satellite platform was developed by the UR Rao Satellite Centre (URSC), which, according to NSIL, “would enable low-cost access to space by providing a dedicated platform for payloads for earth imaging, ocean and atmospheric studies, microwave remote sensing, and space science missions with a quick turnaround time.”
A satellite bus, also known as a spacecraft bus, is a model that is frequently used to build satellites or spacecraft. The bus is the spacecraft’s infrastructure, and it is responsible for providing sites for payload.
According to the Indian Space Research Organization (ISRO), the small satellite project is intended to provide a platform for stand-alone payloads for earth imaging and science missions with a short turnaround time, and “two kinds of buses have been configured and developed: the IMS-1 and IMS-2 buses” in order to “make versatile platforms for different kinds of payloads.”
