Indian Space Research Organization (ISRO) Chairman K Sivan praised the successful launch of RISAT-2BR1 and nine commercial satellites by the Polar Satellite Launch Vehicle (PSLV) on its fiftieth flight (PSLV-C48) from Satish Dhawan Space Center ( SDSC)) SHAR in Sriharikota, Andhra Pradesh.
After the launch, he found that the launch was an important milestone in the history of PSLV. On this occasion Sivan published a book called "PSLV @ 50". "Today we have reached an important milestone in the history of PSLV with the successful start of his 50th mission." He added that this versatile carrier launched 52.7 tons into space, 17% of which belong to customer satellites. Sivan also recognized the efforts of the launch vehicle and satellite teams to accomplish this mission in a short time.
The PSLV-C48 started at 3:25 p.m. (IST) from the First LaunchPad. After 16 minutes and 23 seconds, RISAT-2BR1 was successfully injected into an orbit of 576 km. Then nine commercial satellites were injected into their intended orbits. After the separation, the two RISAT-2BR1 solar arrays were used automatically and the ISRO Telemetry Tracking and Command Network in Bengaluru took control of the satellite. The satellite will be brought into its final operational configuration in the coming days.
RISAT-2BR1 is a radar imaging earth observation satellite weighing approximately 628 kg. The satellite will provide agriculture, forestry and civil protection services. RISAT-2BR1 is used for five years. The nine customer satellites of Israel, Italy, Japan and the United States were precisely injected into their intended orbits. These satellites were launched under a commercial agreement with NewSpace India Limited (NSIL).
PSLV-C48 is the 2nd flight of PSLV in the "QL" configuration (with 4 fixed motors). In addition to the 50th launch of PSLV, the launch on Wednesday was also the 75th launch mission from SDSC SHAR, Sriharikota.
ISRO said on Twitter: "A dream has come true for more than 7,000 visitors who witnessed the launch of PSLV-C48 live from the Viewers Gallery in Sriharikota."
The PSLV is a four-stage rocket, with the first and third stages using solid rocket motors, while the second and fourth stages use liquid rocket motors. It is considered the most reliable ISRO launcher since 47 of its 49 missions have been successfully flown. The only missions with the PSLV missile failed in 1993 (first launch) and 2017 (41st launch).
In its first mission, there was a software bug in an on-board control and control processor, while the 2017 bug was due to the heat shield (the bulbous upper part containing the satellite) not detaching, preventing the satellite from entering orbit brought.
