EXPERIMENTAL AND SMALL SATELLITES LAUNCHED BY ISRO

EXPERIMENTAL AND SMALL SATELLITES LAUNCHED BY ISRO
General KnowledgeExperimental SatellitesISRO has launched many small satellites mainly for the experimental purposes. This experiment includes Remote Sensing, Atmospheric Studies, Payload Development, Orbit Controls, and Recovery Technology etc.

Small SatellitesThe small satellite project is envisaged to provide platform for stand-alone payloads for earth imaging and science missions within a quick turnaround time. 

For making the versatile platform for different kinds of payloads, two kinds of buses have been configured and developed.

Indian Mini Satellite -1 (IMS-1)IMS-1 bus has been developed as a versatile bus of 100 kg class which includes a payload capability of around 30 kg. The bus has been developed using various miniaturization techniques. The first mission of the IMS-1 series was launched successfully on April 28th 2008 as a co-passenger along with Cartosat 2A. Youthsat is second mission in this series and was launched successfully along with Resourcesat 2 on 20th April 2011.

Indian Mini Satellite -2 (IMS-2) BusIMS-2 Bus is evolved as a standard bus of 400 kg class which includes a payload capability of around 200kg. IMS-2 development is an important milestone as it is envisaged to be a work horse for different types of remote sensing applications. The first mission of IMS-2 is SARAL. SARAL is a co-operative mission between ISRO and CNES with payloads from CNES and spacecraft bus from ISRO.
