I-2K is a satellite bus developed by Indian Space Research Organisation (ISRO), and marketed by Antrix Corporation.[6] It is a standard bus for 2,000kg 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.[7] I-2K platform is targeted towards satellites in liftoff mass in range of 1500–2500kg.[8]
Features of I-2K
Launch Mass: 2,000–2,300kg (4,400–5,100lb).
Dimensions: 1.65 * 1.53m in plan & 3.0m in height.
I-3K or the INSAT 3000 is a satellite bus developed by Indian Space Research Organisation (ISRO), and marketed by Antrix Corporation and New Space India Ltd.[13][14] It is the standard bus for 3,000-kg class satellites; the 'I' in I-3K stands for INSAT, a group of communication satellites developed and launched by ISRO. The I-3K bus can supply DC power up to 6500 watts, and is suitable for satellites with lift-off mass in range of 3,000-3,400kg.[15][16][17]
I-4K is a satellite bus being developed by the Indian Space Research Organisation (ISRO).[22][23] It will be a standard bus for 4,000–6,500kg (8,800–14,300lb) class communication satellites.[24] The I in I-4K stands for INSAT, a group of communication satellites developed and launched by ISRO. The I-4K spacecraft bus can supply DC power of 10 to 15 kilowatts.[22][25]
I-6K is a Satellite bus developed by Indian Space Research Organisation (ISRO)[26] It will be a standard bus for 4,000–6,500kg (8,800–14,300lb) class communication satellites;[27] the I in I-6K stands for INSAT and 6 signifies that it can support satellites up to 6,000 kg in weight. The I-6K spacecraft bus can supply DC power of 10 to 15 kilowatts.
