Indian Mini Satellite-1 (IMS-1) is a minisatellite developed by ISRO for remote sensing. Weighing 83 kg at lift-off, IMS-1 incorporates many new technologies and has miniaturised subsystems. IMS-1 carries two optical payloads - a Multispectral camera (Mx Payload) and a Hyperspectal camera (HySI Payload). Both Mx and HySI payloads operate in the visible and near infrared region of the electromagnetic spectrum. The resolution (the smallest ground feature that can be distinguished clearly) of Mx camera is 37 metre while that of HySI is about 506 metre. The imagery from Mx camera are provided to the developing countries while those from HySI are meant for usage in India. The versatile IMS-1 has been specifically developed to carry different payloads in future without significant changes in it and has a design life time of two years. IMS-1 is flown as an auxiliary payload on board PSLV-C9 along with the main payload, CARTOSAT-2A.[ISRO]
