The Indian Space Research Organisation (ISRO) has begun transferring IMS-1 Satellite Bus technology to Alpha Design Technologies, a Bengaluru-based private company. The transfer was facilitated by ISRO’s commercial arm NewSpace India Limited (NSIL) through an agreement.

Key Highlights:

• The IMS-1 satellite bus was developed by the UR Rao Satellite Centre.
• It is a small satellite platform designed to enable lowcost access to space.
• The bus can serve as a dedicated vehicle for many different payloads, facilitating Earth imaging, ocean and atmospheric studies, microwave remote sensing and space science missions.
• The bus weighs about 100 kilograms and can carry a 30-kilogram payload. The solar arrays onboard generate 330 watts of power.
• It comes with four reaction wheels with a 1 Newton thruster that is good for pointing accuracy with an accuracy threshold of 0.1 Degrees.
• The bus was used in previous ISRO missions like IMS-1, Youthsat and Microsat-2D.
