Recently, the Indian Space Research Organisation (ISRO) announced that it began transferring IMS-1 Satellite Bus technology to Alpha Design Technologies.

About Indian Mini Satellite-1: 


  • It was developed by the UR Rao Satellite Centre of Indian Space Research Organisation (ISRO).
  • It is a small satellite platform designed to enable low-cost access to space.
  • Features
    • The IMS-1 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.
    • It was used in previous ISRO missions like IMS-1, Youthsat and Microsat-2D.
  • It 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.


Q1) What is Microwave remote sensing?

Microwave remote sensing is a technique used to collect information about the Earth's surface and atmosphere using microwave signals. This technology utilizes microwave radiation, which has longer wavelengths compared to visible light, making it suitable for various applications, such as weather monitoring, agriculture, environmental monitoring, and Earth observation.
