INSAT Satellite bus


The INSAT Satellite Bus is a series of satellite buses that have been manufactured by the Indian Space Research Organisation and marketed by NewSpace India Limited. It consist of five different versions; ''I-1K, I-2K, I-3K, I-4K& I-6K.''

I-1K

I-1K is a satellite bus developed by the Indian Space Research Organisation and marketed by Antrix Corporation. The I-1K bus is designed to be compatible with lightweight geostationary satellites and is commonly used for meteorological satellites.The IRS or Indian Remote Sensing Satellite bus are also built on I-1K.

Design

  • The I-1K bus can be used for satellites in the lightweight category, with a launch mass between.
