India's PSLV launches record 104 satellites in a single flight

In its thirty-ninth flight (PSLV-C37), ISRO's Polar Satellite Launch Vehicle successfully launched the 714kg Cartosat-2D satellite along with 103 co-passenger satellites on 15th February from Satish Dhawan Space Centre SHAR, Sriharikota.

The launch marked the thirty-eighth consecutive successful mission of the workhorse PSLV.  The total weight of all the 104 satellites carried on-board PSLV-C37 was 1,378kg.

PSLV-C37 lifted off as planned at 9:28 am IST from the First Launch Pad.  After a flight of 16 minutes 48 seconds, the satellites achieved a polar Sun Synchronous Orbit of 506km inclined at an angle of 97.46 degree to the equator, very close to the intended orbit.

Over the following 12 minutes, all 104 satellites successfully separated from the PSLV fourth stage in a predetermined sequence beginning with Cartosat-2D, followed by INS-1 and INS-2.  The total number of Indian satellites launched by PSLV now stands at 46.

After separation, the two solar arrays of Cartosat-2 were deployed automatically and ISRO's Telemetry, Tracking and Command Network (ISTRAC) at Bangalore took over control of the satellite. In the coming days, the satellite will be brought to its final operational configuration, following which it will begin to provide remote sensing services using its panchromatic and multispectral cameras.

Of the 103 co-passenger satellites carried by PSLV-C37, two – ISRO Nano Satellite-1 (INS-1) weighing 8.4kg and INS-2 weighing 9.7kg – are technology demonstration satellites from India. The remaining 101 co-passenger satellites carried were international customer satellites from the U.S. (96), the Netherlands (1), Switzerland (1), Israel (1), Kazakhstan (1) and UAE (1).
