PSLV-C45 being transported to the launch pad at Sriharikota Space Port

The Indian Space Research Organisation (ISRO) is all set to achieve a new feat by launching the Polar Satellite Launch Vehicle (PSLV) C45 on April 1 from the Satish Dhawan Space Centre, Sriharikota as this will be the first mission from the Indian space agency which will put satellites in three different orbits. The most important payload of the PSLV-C45 rocket will be the electronic intelligence satellite EMISAT which will help the Defence Research and Development Organisation (DRDO) in military's research and development.

Other than the EMISAT satellite, the PSLV-C45 rocket will also be launching 28 international satellites from Spain (1), Lithuania (2), Switzerland (1) and the United States (24). On the other hand, EMISAT, which weighs around 436 kg, is based on ISRO’s Indian Mini Satellite-2 (IMS-2) platform and is intended for electromagnetic spectrum measurement for the Indian space agency and DRDO.

Five Key Points To Know About ISRO's New Satellite For Indian Military

1. The countdown for the ISRO PSLV-C45 EMISAT launch began at 6.27 am on March 31 at the rocket port situated at Sriharikota in Andhra Pradesh. On the other hand, the ISRO PSLV-C45 EMISAT launch is scheduled for 9:30 am on 1st April 2019

2. The PSLV-C45 is the first launch vehicle to use solar panels in the fourth stage rocket (PS4). The PS4 has three payloads including the Automatic Packet Reporting System (APRS) from AMSAT (Radio Amateur Satellite Corporation), Automatic Identification System (AIS) from ISRO, and the Advanced Retarding Potential Analyser (ARIS) from Indian Institute of Space Science and Technology (IIST) which will be used for Ionospheric Studies

3. This will be the 47th mission for PSLV programme, the PSLV-C45 will first launch the electronic intelligence satellite EMISAT into a 749 km orbit after which, the launch vehicle will be brought down to the 504 km orbit to launch 28 satellites. This will be followed by the launch of APRS, AMSAT and ARIS into the 485 km orbit

4. The whole process will take around 180 minutes from the ISRO PSLV-C45 EMISAT launch at 9:30 am

5. Weather conditions play an important part in ISRO PSLV-C45 EMISAT launch as it was previously scheduled for March 21 but later postponed to April 1, 2019
