Cartosat-2 launch: Here's all you need to know about India'latest state light
The Indian Space Research Organisation (ISRO) launched earth observation satellite Cartosat-2 series and 30 co-passenger satellites from Sriharikota in Andhra Pradesh.
Here is all you need to know
Cartosat-2 is a remote sesnsing satellite with the resolution of 0.6 metres which can spot even smaller objects within a square of 0.6 m by 0.6 m. The ISRO official succinctly defined it thus: High-resolution scene specific spot imagery.
The previous satellite in the series, which had a resolution of 0.8 metres, took images that helped India carry out its precise strikes on seven terror camps across the Line of Control last year.
This satellite has been launched by the Indian Space Research Organisation's (ISRO) Polar Satellite Launch Vehicle, which will be on its 40th flight.
The Cartosat-2 series satellite weighs 712 kg, according to ISRO. Out of the 30 nano satellites which will launch with Cartosat-2, 29 are foreign and one is Indian. The 30 satellites will together weigh 243 kg.

Satellite-based chip
systems developed by ISRO will be used to alert road users at unmanned
level crossings about approaching trains. These chips will also help the
railways in tracking train movement on a real-time basis.
Initially, on a pilot basis the ISRO-developed integrated circuit (IC)
chips will be installed in the Mumbai and Guwahati Rajdhani trains.
Hooters will be installed at 20 unmanned level crossings on Rajdhani
routes for Guwahati and Mumbai.
The system will warn the road users by hooters once a train approaches
an unmanned level. The hooters will get activated when the train is
present at a distance of about 500 metres from the level crossing,
warning both road users as well as the train driver near the crossing.
The sound of the hooters will become louder as the level crossing nears,
and finally it will become silent after the passage of the train.
In a phased manner, more trains would be equipped with the
ISRO-developed integrated circuit (IC) chips.
The satellite based system will also be used for tracking trains about
their movement on real time basis. It will be useful to passengers as at
present the movement of trains are tracked manually.
Need
Safety at unmanned level crossings is a matter of concern for the Indian
Railways as around 40% of accidents involving the railways happen in
unmanned crossings. India has a total 10,000 unmanned railway crossings
in the country. The railways has set a target for eliminating all the
railway crossings in the next 2-3 years. It has eliminated 1,148
unmanned crossings in 2014-15 and 1,253 in 2015-16.
The new technology will also help Indian railways at the time of train
accidents as it can be used to get details about the exact location of
trains and topography.

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
