I-2K is a satellite bus developed by Indian Space Research Organisation (ISRO), and marketed by Antrix Corporation.[1] It is a standard bus for 2,000 kg class satellites; the 'I' in I-2K stands for INSAT, a group of communication satellites developed and launched by ISRO. The satellite buses developed by ISRO are specifically developed for small and medium weight satellites. I-2K spacecraft bus can supply DC power up to 3000 watts.[2] I-2K platform is targeted towards satellites in liftoff mass in range of 1500–2500 kg.[3]
