On early Sunday morning, the Indian Space Research Organisation started a 28-hour countdown after which on Monday at 9:27 am ISRO launched the PSLV-C45/EMISAT mission today in the morning. The mission comprises an Indian electronic spy satellite advanced cooperatively by ISRO and the Defense Research and Development Organisation (DRDO), and 28 other satellites from many several countries through its commercial arm Antrix Corporation Limited.
Days after Mission Shakti, India puts into orbit defence satellite EMISAT
Today’s launch arises just six days after India test-fired an anti-satellite (ASAT) missile in the Mission Shakti operation.
ISRO said that the countdown for the launch on the PSLV, in its 47th flight was started at 6:27 am on Sunday which is the 71st launch vehicle mission for Sriharikota. With this, India seeks to originate a new surveillance satellite with a special mission of the Polar Satellite Launch Vehicle (PSLV C-45) that has several originals.
The PSLV-C45 is basically the 47th mission of the Indian Polar Satellite Launch Vehicle (PSLV) program. India launched the Polar Satellite Launch Vehicle (PSLV)-C45 which has put 29 satellites, comprising one for electronic intelligence also with 28 customer satellites from various different countries.
The PSLV-C45 was launched from the Second launch pad of the Satish Dhawan Space Centre which is located in Sriharikota, Andhra pradesh, India. The Project was under the supervision of K.Sivan, who is the chairman of ISRO.
The PSLV C45 rocket carries the primary payloads such as EMISAT as well as the secondary payloads like M6P, Bluewalker1, four Lemur-2 out of a total of thirty satellites. On the other hand, EMISAT is developed by DRDO and the EMISAT satellite is established on the IMS-2 bus inherited from SARAL.
It was the first flight of PSLV-QL with 4 strap-on boosters and placed a primary payload EMISAT as well as a secondary payload of Lemur M6P in sun-synchronous orbits.
ISRO launches EMISAT, 28 other satellites to locate enemy radar
The PSLV-QL lifted off from the Satish Dhawan Space Center with the 29 payloads, placing them in 3 different orbits over 3 hours which is a milestone that ISRO is trying for the first time ever.
In this mission, the PS4 hosts three payloads such as Automatic Identification System (AIS) from ISRO, Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation), India as well as the Advanced Retarding Potential Analyzer for Ionospheric Studies (ARIS) which is from Indian Institute of Space Science and technology (IIST).
The 28 global customer satellites are basically from four different countries such as Lithuania, Spain, Switzerland and the United States of America. ISRO said that all these satellites are being launched under commercial provisions and measures.
The PSLV-C45/EMISAT is a special mission as it is the ISRO’s first ever effort to place satellites in three different orbits in a single satellite launch mission. On the other hand this will also test a new variant of the PSLV rocket “the PSLV-QL, which has 4 extra strap-on boosters to give it an enormous extra thrust.
The mission basically starts with the launch of the EMISAT satellite into the orbit at 780 km, then it will insert additional 29 satellites into the orbit at 504 km and later the fourth stage will move to 485 km orbit to move out scientific trials.
The launch was initially arranged for 21 March 2019, but was then postponed to 1 April to make sure the system readiness for a perfect launch.
