ISRO’s PSLV-C49 successfully launches EOS-01 and nine customer satellites from Sriharikota

Today, India’s Polar Satellite Launch Vehicle, in its fifty first flight (PSLV-C49), successfully launched EOS-01 along with nine international customer satellites from the First Launch Pad of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota.

PSLV-C49 lifted-off at 1511 Hrs (IST), after a delay of nine minutes because of inclement weather conditions observed during countdown. After 15 minutes and 20 seconds, EOS-01 was successfully injected into its orbit. Subsequently, nine commercial satellites were injected into their intended orbits. After separation, the two solar arrays of EOS-01 were deployed automatically and the ISRO Telemetry Tracking and Command Network at Bengaluru assumed control of the satellite. In the coming days, the satellite will be brought to its final operational configuration.


“PSLV-C49 successfully placed all ten satellites precisely into their orbit” Chairman, ISRO, Dr. K. Sivan declared.  He congratulated both the launch vehicle and satellite teams for rising to the occasion amidst the Covid-19 pandemic restrictions. Dr. K. Sivan also briefed about the upcoming missions.

EOS-01 is an earth observation satellite, intended for applications in agriculture, forestry and disaster management support.


The nine customer satellites from Lithuania (1), Luxembourg (4) and USA(4) were launched under a commercial arrangement with NewSpace India Limited (NSIL).  


PSLV-C49 is the 2nd flight of PSLV in 'DL' configuration (with 2 solid strap-on motors). Besides being the 51st launch of PSLV, today’s launch was also the 76th launch vehicle mission from SDSC SHAR, Sriharikota.


Addressing his team of scientists, ISRO chief K Sivan said, “Today I am extremely happy to declare that PSLV-C49 successfully placed earth operation satellite EOS-01 as well as nine customer satellites precisely into 575 kilometer orbit.”

“Subsequent to this mission, the satellite started operating it’s own functions. The solar panel of the satellite also successfully deployed,” ISRO chief said.


EOS-01 is an advanced earth observation satellite whose synthetic aperture radar (SAR) has an all-weather and day-and-night observation capability.

The customer satellites include 4 each from the USA and Luxembourg and 1 from Lithuania with objectives ranging from multi mission remote sensing to maritime applications and technology demonstration.


This was ISRO’s first satellite launch since the onset of the Covid-19 pandemic , which has slowed down all space activities since March.


The last satellite ISRO had launched from Indian soil was PSLV-C48 which also carried a surveillance satellite, Risat-2BR1, on December 11, 2019. 


Communication satellite GSAT-30 was the only ISRO satellite launched this year on January 17 but from the European spaceport in French Guyana.


After the PSLV-C49 mission, ISRO is targeting to launch PSLV-C50 mission carrying GSAT-12R communication satellite in December.
