Resourcesat 2A is an earth observation satellite of the Indian space agency ISRO and the successor satellite to ResourceSat-1 and ResourceSat-2 .

It was launched into sun-synchronous orbit on December 7, 2016 at 4:54 UTC by a PSLV launcher from the Satish Dhawan Space Center rocket launch site.

Like Resourcesat 2, the three-axis stabilized satellite is equipped with three cameras that work in the visible and infrared range and deliver a maximum resolution of 5.8 meters. They are further developed versions of the cameras that were used in the ResourceSat-1, which was launched in 2003. With the high-resolution line scanner LISS-4 (Linear Imaging Self Scanner), the swath width has been increased from 23 to 70 km. At the same time, the LISS-4 camera can be swiveled up to 26 ° from the vertical for recordings.

The satellite uses reaction wheels , magnetic torquers and hydrazine thrusters for stabilization . The two solar cell wings with a size of 1.4 × 1.8 m each deliver an output of 1,250 W (End Of Life) and are supplemented by two nickel-cadmium batteries with a capacity of 24 Ah. The recorded images are stored on two solid-state drives with a capacity of 200 gigabytes each.
