Polar Satellite Launch Vehicle (PSLV) Current Affairs

ISRO successfully launches GSAT-17 Satellite

ISRO has successfully launched GSAT-17 communication Satellite onboard the Ariane-5 launch vehicle from the Guiana Space Center at French Guiana on June 28. GSAT-17 will be the ISRO’s third satellite that is launched within a span of three months.

Salient Highlights

The 3,477-kg GSAT 17 communication satellite will be placed in the geostationary orbit and will have a mission life of 15 years.

The satellite will be an addition to the current fleet of 17 Indian communication satellites that are already providing services from space.

Apart from providing communication services, the satellite will provide meteorological and satellite-based data to help rescue services which were earlier provided by geostationary satellites called Indian National Satellite System (INSAT).

GSAT-17 will provide continuity of services of operational satellites in C, extended C and S bands

Once launched, ISRO’s Master Control Facility at Hassan in Karnataka and Bhopal in Madhya Pradesh will take over and place the satellite in geostationary orbit. GSAT-17 was designed and assembled at the ISRO Satellite Centre in Bengaluru.

In addition, GSAT-17 will also launch communication satellite Hellas Sat 3-Inmarsat S EAN. Hellas Sat 3 will provide directly to home television and telecom services across Europe, West Asia and South Africa. Inmarsat is set to provide in-flight Internet facilities for European airlines.

Launch Vehicle

As ISRO is yet to have a launcher that is capable of lifting payloads above 2,000 kg. ISRO has just started testing the GSLV-Mark III for this purpose.

GSAT-17 will be the 21st Indian launch for the Arianespace. ISRO’s upcoming GSAT- 11 which will weigh more than 5,000 kg will also be launched by Arianespace.

ISRO to launch Earth Observation Satellite

Indian Space Research Organisation (ISRO) is all set to launch earth observation satellite Cartosat-2 series weighing 712 kg and 30 nano-satellites using Polar Satellite Launch Vehicle (PSLV).

Salient Highlights

Out of the 30 nano-satellites, 29 will be of foreign origin and one will be of India’s. The 29 nano-satellites will be from 14 countries such as Austria, Belgium, Britain, Chile, Czech Republic, Finland, France, Germany, Italy, Japan, Latvia, Lithuania, Slovakia, and the US. These 29 satellites will be launched by ISRO as part of the commercial arrangements between ISRO’s commercial arm, the Antrix Corporation Ltd with these nations.

The 30 satellites will together weigh 243 kg. The total weight of the 31 satellites would be 955 kg. The PSLV-XL will be launched from the Sriharikota rocket port.

The rockets will be placed into a 505 km polar sunsynchronous orbit (SSO).

This will be the seventeenth flight of PSLV in ‘XL’ configuration. It uses solid strap-on motors.

PSLV

Polar Satellite Launch Vehicle (PSLV) is the third generation launch vehicle of India which is hailed as the reliable and versatile workhorse launch vehicle of India. PSLV’s first successful launch took place in October 1994. Since then the launch vehicle has 38 consecutively successful missions by February 2017. It has launched 46 Indian satellites and 180 foreign satellites between 1994-2017.

PSLV is also India’s first launch vehicle to be equipped with liquid stages. There are three variants of PSLV, namely, PSLV-G, PSLV-CA, PSLV-XL.

PSLV was used to successfully launch Chandrayaan-1 in 2008 and Mars Orbiter Spacecraft in 2013.
