ISRO to launch 9 nano/micro American satellites during 2015-16

This will be the first time that ISRO will launch US satellite. These satellites will go as piggyback on PSLV's (Polar Satellite Launch Vehicle), officials said.

ISRO to launch 9 nano/micro American satellites during 2015-16
BENGALURU: Indian Space Research Organisation ( ISRO) will be launching nine nano/ micro satellites for United States during 2015-16 time frame.

This will be the first time that ISRO will launch US satellite.

"As on date, Antrix Corporation Ltd, the commercial arm of ISRO, has signed agreement to launch about nine nano/micro (US) satellites during 2015-2016 time frame," ISRO Director Public Relations Deviprasad Karnik said.

These satellites will go as piggyback on PSLV's (Polar Satellite Launch Vehicle), officials said.

So far, 45 satellites belonging to international customers from 19 countries have been launched successfully by ISRO's satellite launch vehicles.

Meanwhile Dr K Sivan, Director of Vikram Sarabhai Space Centre, Thiruvananthapuram, said that the first Reusable Launch Vehicle-Technology Demonstration (RLV-TD) would be held during the end of this year.

"The first RLV technology demonstration will be held in the end of 2015," Sivan told reporters in Thrissur.

RLV-TD is a series of technology demonstration missions that have been considered as a first step towards realising a Two Stage To Orbit (TSTO) fully re-usable vehicle.

Sivan also said that the fully indigenous developed Geo-synchronous Satellite Launch Vehicle (GSLV) D6 would be launched by end of this month, adding the cost of the 2.5 tonne vehicle would be around Rs 250 crore.

The launch of GSAT 6 is expected to give a huge impetus in the field of communication sector in the country.

There are three key satellite orbits - high, medium and low. The high-earth orbit is at a height of about 35,780 km; the mid-earth and low-earth orbits are 2,000-35,780 km and 180-2,000 km, respectively.

A geosynchronous satellite orbits the earth at the same speed as the planet's rotation on its axis and hence remains in the same position with respect to the earth.

The most commonly used low-earth or bit is the polar orbit. Satellites placed in this orbit move around the earth from pole to pole.How are satellites placed in orbits?

Launch vehicles (LVs) are the instruments used to put satellites in their respective orbits.

India took its first step in outer space on November 21, 1963 when Indian scientists launched the first sounding rocket from Indian soil.

Although India started developing launch ve t hicles in the early 1970s, it took about two decades to reach operational ability.

Satellite Launch Vehicle (SLV) was India's first experimental launch vehicle capable of placing 40 kg payloads in low-earth orbits.

After the initial failure in a 1979 launch, on July 18, 1980 SLV-3 successfully launched Rohini (RS-1) making India the sixth country to have the capability of launching satellites.

After the success of the SLV programme, ISRO launched the Augmented Satellite Launch Vehicle (ASLV) programme. This launch vehicle augmented the payload capacity to 150 kg, thrice that of SLV, and was used to validate critical technologies for future launch vehicles.

Polar Satellite Launch Vehicle is the system used to launch low orbit satellites to sun synchronous polar orbits. It was the next stage of the SLV and ASLV programmes and was developed to launch Indian Remote Sensing (IRS) satellites.

The first developmental launch of PSLV was done in 1993 and the vehicle failed to put remote sensing satellite IRS-1E into orbit. The vehicle became operational after the launch of the IRS-1D satellite on September 29, 1996. Since 1999, the vehicle has also launched foreign satellites.

PSLV has launched over 40 satellites for 19 countries. It was also used for launching Chandrayaan-1 and the Mars Orbiter Mission.

Despite the success of the PSLV programme, India was not capable of launching INSAT type heavy communication satellites in geosynchronous orbits. Such capability was only possible after the development of cryogenic engines based on liquefied gas.

India's Geosynchronous Satellite Launch Vehicle (GSLV) programme started in the 1990s and according to a 1991 agreement, a Russian company was supposed to provide the engine for the cryogenic stage of the launch. In 1992, the US imposed sanctions and the Russian company backed out of the deal.

Later, Russia agreed to sell seven cryogenic engines to India. These were used to fuel the early GSLV launches. In 2014, India succeeded in a GSLV launch using indigenous cryogenic technology.

ISRO's PSLV-C28 carries 5 British satellites on July 10 from the Satish Dhawan Space Centre at Sriharikota, about 90 km from Chennai.
