ResourceSat-2 is intended to continue the remote sensing data services to global users provided by ResourceSat-1, and also provide data with enhanced multispectral/spatial coverage. ResourceSat-2 data is useful for applications such as urban planning, mapping, vegetation discrimination, land mapping and natural resources management.

The spacecraft mainframe is of IRS-1C/1D -P3 heritage. The structure consists of two modules, the main platform and the payload module. The main platform is built around a central load bearing cylinder of 915 mm diameter and consists of four vertical panels and two horizontal decks. The bottom of the cylinder is attached to an interface ring which interfaces with the launch vehicle. The vertical panels and the horizontal decks carry the subsystem packages.

The spacecraft is three-axis stabilised using reaction wheels, magnetic torquers and hydrazine thrusters. Attitude is sensed with star sensors, Earth sensors, and gyros. Various attitude sensors, SPS (Satellite Positioning System) and data transmitting antennas are mounted on the outside surfaces of the equipment panels and the bottom deck. Two star trackers are mounted with skewed orientation on the top deck. The payload module in turn is comprised of a two-tier system, the payload module deck and the rotating deck.

The payload module deck accommodates LISS-3, AWiFS-A and AWiFS-B camera modules. The LISS-4 camera is mounted on a rotating deck which is attached to a PSM (Payload Steering Motor) which can rotate by ± 26° to provide an event monitoring capability. 

ResourceSat-2 operates in a circular, Sun-synchronous, near-polar orbit with an inclination of 98.69 deg, at an altitude of 817 Km. The satellite takes 101.35 minutes to complete one revolution around Earth and completes about 14 orbits per day. The entire Earth is covered by 341 orbits during a 24 day cycle.

Mission control is handled by ISTRAC in Bangalore, India with telemetry, tracking and command at further ground stations in Lucknow, Biak and Mauritius. Data reception is done at NRSC, Shadnagar, India and DLR in Neustrelitz, Germany.
