India’s Polar Satellite Launch Vehicle (PSLV), in its 47th mission (PSLV-C45) successfully launches EMISAT and 28 international customer satellites from Satish Dhawan Space Centre SHAR, Sriharikota, today at 9.27 am.
Weighing about 436 kg, EMISAT based on ISRO’s Indian Mini Satellite -2 (IMS-2) bus platform. The satellite is intended for electromagnetic spectrum measurement. The PS4 orbital platform is envisaged to provide a microgravity environment for research organisations and academic institutes to perform experiments.
In this mission, the PS4 hosts three payloads, namely, Automatic Identification System (AIS) from ISRO, Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation), India and Advanced Retarding Potential Analyzer for Ionospheric Studies (ARIS) from Indian Institute of Space Science and technology (IIST).
The 28-international customer satellitesare from four countries, viz. Lithuania, Spain, Switzerland and USA. All these satellites are being launched under commercial arrangements.
“It is a special mission for us. We will be using a PSLV rocket with four strap-on motors. Further, for the first time we will be trying to orbit the rocket at three different altitudes,” ISRO Chairman K. Sivan said earlier. The PSLV is a four-stage engine expendable rocket with alternating solid and liquid fuel.
