On 12 July2010, ISRO (Indian Space Research Organisation) successfully launched PSLV C-15, which placed five satellites into their orbits. Out of five three are foreign satellites while two are Indian satellites. The launch took place at Satish Dhavan Space centre in Sriharikota district of Andhra Pradesh.

 

The names of the satellites are as following;

 

1. CARTOSAT- 2B
2. STUDSAT
3. ALSAT-2A
4. AISSAT-1 (NLS-6.1)
5. TISAT-1 (NLS-6.2)

CARTOSAT-2B and STUDSAT are Indian Satellites while ALSAT-2A, AISSAT-1(NLS-6.1) and TISAT-1(NLS-6.2) are foreign satellites.

CARTOSAT- 2B

 

CARTOSAT-2B with the mass of 694 kg is a Remote Sensing Satellite which is 17th in the series of Remote Sensing Satellites. Equipped with Panchromatic Camera the satellite can take the image of 9.6km long geographical strip. The images of specific spots sent back by the satellite will be used for Cartographic and other purposes. The satellite can be used for preparing detailed forest type maps, tree volume estimation, crop invention, village/town settlement mapping and planning for development, rural connectivity, canal alignment, coastal land form, mining monitoring and others.

With the launch of CARTOSAT-2B, ISRO will have 10 remote sensing satellites in orbit- IRS1D, Resourcesat1, TES, CARTOSAT 1, 2 and 2A, IMS 1, RISAT-2, OCEANSAT 1 and 2.
India is a world leader in the remote sensing data market, earning significant amount. The other remote sensing satellites that are ready to be launched by the end of 2010 or by early 2011 are RISAT, Resourcesat and Megha-Tropiques.


STUDSAT

STUDSAT (Student Satellite) with the mass of less than one kg is the first Pico-Satellite developed in India by a group of seven engineering colleges from Karnataka and Andhra Pradesh. The main objective of this satellite is to promote space technology in educational institutions and encourage research and development in miniature satellites. And to establish a communication link between the satellite and ground station, capturing the image of earth with a resolution of 90 metres and transmitting the payload and telemetry data to the earth station.

Three Foreign Satellites

Besides, CARTOSAT 2-B and STUDSAT three foreign satellites were also launched by PSLV C-15.
1. ALSAT 2A is a small satellite from Algeria for remote sensing purpose. Its weight is 116kg.
2. AISSAT-1(NLS6.1) developed by Space Flight Laboratory of the University of Toranto, Canada for testing various satellite technologies.
3. TISAT-1(NLS-6.2) built by University of Applied Sciences of Switzerland for tasting various satellite technologies.

PSLV C-15

Polar Satellite Launch Vehicle better known by its abbreviated name PSLV is the first operational launch vehicle of ISRO. The satellite is capable of launching 1600 kg satellites in 620km in sun-synchronous polar orbit and 1050 kg satellite in geo-synchronous transfer orbit. PSLV consists of four stages using solid and liquid propulsion system alternately. The first stage is one of the largest solid propellant boosters in the world.

The Difference between PSLV and GSLV

GSLV (Geosynchronous Satellite Launch Vehicle) is a three-stage vehicle with the first stage being solid-propelled, the second liquid-propelled (with hypergolic fuels) and the third and final stage (with cryogenic fuels) being liquid-propelled as well. Whereas, PSLV has four stages using solid and liquid propulsion system alternately. GSLV is capable of placing INSAT-II class of satellites.
