I-2K

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]

List of satellites launched using I-2K platform

• INSAT series (3B | 3C | 3D | 3E | 4C | 4CR)
• IRS series (1C | 1D | P3)
• GSAT series (1 | 2 | 3 (EDUSAT) | 4 | 5P | 6 | 7 | 9^[4] | 14^[5])
