In mid of last month, Indian space agency. ISRO, had invited an expression of Interest (EOI) for the complete Transfer of Technology (ToT) of Small Satellite Launch Vehicle (SSLV). Now, in less than a month, ISRO on Friday announced that it has transferred the IMS-1 Satellite Bus Technology to Adani Group-owned Alpha Design Technologies Pvt. Ltd., a Bengaluru-based company engaged in development / manufacture / supply of almost all types of defence electronics, avionics, simulation, UAVS, AFV equipment & systems.

Alpha Design is one of the two private players identified to receive the transfer of this technology through Interest Exploratory Note (IEN) published by NSIL. The other private entity to receive the technology transfer is yet to be disclosed however.

ISRO's commercial arm NewSpace India Limited (NSIL), facilitated the technology transfer to Alpha Design through an agreement signed during an event held at the NSIL headquarters on August 2, 2023.

The Technology Transfer Documents were formally handed over by Shri. D Radhakrishnan, Chairman and Managing Director of NSIL to Col. H. S. Shankar (Retd.) VSM, Chairman and Managing Director of Alpha Design. 

"This transfer marks the beginning of satellite-bus technologies developed by ISRO being transferred to private industries," said ISRO in a release.

By transferring the IMS-1 technology to the private sector, ISRO and Department of Space aims to bolster India's industrial growth in the space sector and foster technological self-reliance. The development opens up new avenues for private players to contribute to space research and exploration, in line with India's vision to expand its presence in the global space market.

The IMS-1 (Indian Micro Satellite) satellite bus, developed by the U R Rao Satellite Centre (URSC/ ISRO), is a versatile and efficient small satellite platform designed to facilitate low-cost access to space. IMS-1 is an Earth observation satellite in a sun-synchronous orbit, and is the fourteenth satellite in the Indian Remote Sensing (IRS) satellite series built, launched and maintained by ISRO.

The satellite bus serves as a dedicated vehicle for various payloads, enabling Earth imaging, ocean and atmospheric studies, microwave remote sensing, and space science missions while ensuring a quick turnaround time for satellite launches.

IMS-1 bus, weighing about 100 kg, accommodates a 30 kg payload. Solar arrays generate 330 W power with a raw bus voltage of 30-42 V. It offers a 3-axis stabilized with four reaction wheels with a 1 N thruster that provides +/- 0.1 degree pointing accuracy. It is a forerunner for IMS-2 bus technology, capable of improved features. IMS-1 bus is utilised in previous ISRO missions like IMS-1, Youthsat and Microsat-2D.

Founded in 2003, by Col. H.S. Shankar, Akunuri Mohana Rao and Rakesh Dhar Jayal, Alpha Design Technologies is a leading aerospace and defense company based in India. With expertise in engineering, manufacturing, and system integration, ADTL has been a key player in various projects related to defense, space, and homeland security, contributing significantly to India's technological progress in these domains.

In December 2021, Adani Enterprises, through its subsidiary Adani Defence Systems and Technologies, has made an acquisition of Alpha Design Technologies. According to a 2018 report by Business Standard, Alpha Design was acquired by Adani Enterprises for ₹400 crores. 

During peak of pandemic COVID-19, Alpha Design Technologies was among three Indian companies chose to get free license for manufacturing VITAL – a Ventilator indigenously developed by the US space agency NASA's Jet Propulsion Laboratory, in May 2020.

In year 2018, Alpha Design made a 2-year contract with ISRO for assembly, integration and testing of IRNSS satellites. The Indian Regional Navigation Satellite System (IRNSS), with an operational name of NavIC (acronym for Navigation with Indian Constellation; also, nāvik 'sailor' or 'navigator' in Indian languages), is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services.
