The Indian Space Research Organisation (ISRO) has transferred its cutting-edge IMS-1 Satellite Bus Technology to Alpha Design Technologies Pvt. Ltd. This transfer was facilitated by NewSpace India Limited (NSIL), ISRO’s commercial arm, aiming to enable the private space sector in pushing development.

The IMS-1 satellite bus is a versatile and efficient small satellite platform designed by the U R Rao Satellite Centre. Its purpose is to provide low-cost access to space. The bus serves as a dedicated vehicle for various payloads, enabling Earth imaging, ocean and atmospheric studies, microwave remote sensing, and space science missions. It also ensures a quick turnaround time for satellite launches.

Weighing about 100 kg, the IMS-1 bus can accommodate a 30 kg payload. Its solar arrays generate 330 W power with a voltage range of 30-42 V. It offers a 3-axis stabilised system with four reaction wheels and a 1 N thruster for improved pointing accuracy. This technology has previously been used in ISRO missions such as IMS-1, Youthsat, and Microsat-2D, and serves as a precursor to the more advanced IMS-2 bus technology.

This marks the beginning of ISRO-developed satellite-bus technologies being transferred to private industries. The aim is to bolster India’s industrial growth in the space sector and promote technological self-reliance. The transfer opens up new opportunities for private players to contribute to space research and exploration, aligning with India’s plans to expand its presence in the global space market.

Alpha Design Technologies (ADTL) has expertise in engineering, manufacturing, and system integration. With the technology transfer, ADTL is poised to make a substantial contribution to India’s space research and exploration. This will further enhance technological self-reliance and support India’s vision of becoming a major player in the global space market.

This transfer of technology is a significant step towards enhancing private industry participation in the Indian space sector, driving innovation and advancements in the field.
