ISRO schedules ResourceSat-2A launch with the PSLV-C36 mission on 7 December

The thirty eight flight of ISRO’s workhorse rocket, PSLV-C36 is scheduled for a December 7 launch from the First Launch Pad (FLP), at Satish Dhawan Space Centre SHAR, Sriharikota. The XL configuration will be used for the mission, where the PSLV is strapped on with six additional motors. PSLV-C36 will place the ResourceSat-2A into 917 kilometre high polar Sun Synchronous Orbit (SSO).

ResourceSat-2A is a follow on mission to the ResourceSat launched in 2003 and the ResourceSat-2 launched in 2011. The remote sensing data services is provided to a users around the world.

The Linear Imaging Self Scanner (LISS-4) high resolution camera operating in three spectral bands in the Visible and Near Infrared Region (VNIR). The resolution of the camera is 5.8 metres. The LISS-4 camera has a swath of 74 kilometres and revisit every five days.  The swatch is the area on the ground under observation, and the revisit period is the duration after which the same spot on the ground is observed by the imaging instrument.

The LISS-3 captures images in three spectral bands in the VNIR, as well as one spectral band in the Short Wave Infrared Region (SWIR). The LISS-3 has a swath of 141 kilometres and a revisit of 24 days. The third payload is the Advanced Wide Field Sensor (AWIFS) camera operating in three bands in VNIR and one band in SWIR. The spatial resolution on this camera is relatively low, at only 56 metres. The swatch of the AWIFS payload is 740 kilometres, and has a revisit of 5 days. The data rates for all the payloads are 105 MBps. [caption id=“attachment_351224” align=“aligncenter” width=“640”]  RESOURCESAT-2A with one of its solar arrays deployed during ground tests8 of 13.

The Recorders are meant to store images from the sensors, to beam to the ground stations later. There are four stages to the rocket. The separation of the satellite will happen eighteen minutes after the launch. The rocket will achieve a top speed of 7,439 metres per second.

Out of the 121 satellites launched by PSLV, 79 are foreign satellites, and 42 are Indian satellites. PSLV has placed satellites in polar SSOs, Low Earth Orbits (LEO), Geosynchronous Transfer Orbit (GTO) as well as Sub GTOs.
