ISRO PSLV-C45 Launched: What do Satellites Onboard PSLV-C45 Do?

As always, watching ISRO PSLV-C45 EMISAT launch live online is something netizens can do. However, apart from this, Indian Space Research Organisation and space technology enthusiasts will also be able to watch rocket launches live from the ISRO SDSC SHAR facility itself from now on. Although the registrations for watching PSLV-C45 EMISAT launch live have been closed as of now, ISRO fans can register to watch the PSLV-C46, says ISRO on the website.

Phase-1 of visitors' gallery, with 5000 capacity, has gone live at SDSC in Sriharikota on March 31. The Space Theme Park will have a clear line of sight to 2 launch pads, large screens placed to explain launcher and satellite features, and several other attractions such as Space Museum and rocket replicas.

Where to Watch ISRO PSLV-C45 EMISAT Launch Live Online

Those who could not register to be at Sriharikota to watch the PSLV-C45 take-off on 1 April 2019 need not be sad. Viewers can always watch the ISRO PSLV-C45 EMISAT launch live online from 9:00 AM IST onwards on the official ISRO website. Also, Doordarshan usually always relays the launch live from Satish Dhawan Space Centre, Sriharikota, on its YouTube Channel.

What EMISAT and Other Satellites Onboard PSLV-C45 Do?

ISRO has announced that the countdown for the launch of PSLV-C45 began at 06:27 AM (IST) on 31 March 2019 from Satish Dhawan Space Centre, Sriharikota and the launch is scheduled at 09:27 AM (IST) on 1 April. Also, Propellant filling of fourth stage of PSLV-C45 has been completed.

The PSLV-C45 is going to launch 29 satellites, and will place them in two different orbits, says the PSLV-C45 EMISAT Mission curtain raiser video. Not much is being said about the EMISAT satellite apart from the fact that it is 436 Kg and meant for electromagnetic spectrum measurement.

Some other satellites from other countries like the USA that will be launched include FLOCK-4A, LEMURs, BLUEWALKER1, ASTROCAST-2, and so on. What is commendable is the fourth stage of PSLV will be used as an orbital platform to conduct space borne experiments. To achieve the purpose, the stage is equipped with solar panel to generate electrical power in orbit and three Indian payloads which are as follows:

1. Automatic Packet Repeating System (APRS) from AMSAT India: Digital repeater for amateur radio applications, which is meant to assist amateur radio operators in tracking and monitoring position data.
2. Automatic Identification System (AIS) from ISRO: This is meant for automatic identification of ships, by capturing messages transmitted from ships and relaying them to ground stations.
3. Advanced Retarding Potential Analyzer for Ionospheric Studies (ARIS) from Indian Institute of Space Science and Technology (IIST): Meant for structural and compositional studies of the ionosphere.

With the aid of this mission, the Earth’s ionosphere can be studied in real-time, which will help scientists build accurate ionospheric models thus resulting in improvement of accuracy of satellite navigation signals, says the curtain raiser video.
