The GSAT satellites are India's indigenously developed communications satellites, used for digital audio, data and video broadcasting. As of 30 March 2018, 18 GSAT satellites of ISRO have been launched out of which 13 satellites are currently in service
The GSAT series of geosynchronous satellites is a system developed by ISRO with an objective to make India self-reliant in broadcasting services
GSAT-6A is a communications satellite operated by the Indian Space Research Organisation. It features a 6-metre (20 ft) unfurlable S-band antenna similar to the one used on GSAT-6. Around 17 minutes after lifting off , the three stage GSLV Mk.ll rocket flying on GSLV F08 mission successfully injected the satellite into a Geosynchronous Transfer orbit.

Around 17 minutes after lifting off , the three stage GSLV Mk.ll rocket flying on GSLV F08 mission successfully injected the satellite into a Geosynchronous Transfer orbit.
GSAT 6A is a satellite is launched to support the GSAT 6 satellite which launched in August 2015 by ISRO. GSAT 6 satellite launched to improve the communication system, now with the GSAT 6A launch the communication will be better. As two satellite were used in the communication system, so the communication will be two-way communication. The first satellite GSAT 6 launched at the cost of ₹ 269 Crore and the second satellite launched at the cost of ₹ 147 Crore. In order to operate communication system by these satellites a 6-meter (20 ft) unfurlable S-band antenna which is similar to the one used on GSAT-6 has used. The size of S-Band antenna used in GSAT 6A is 3 times more in comparison with another satellite. Hence GSAT 6A will be more capacitive. As this satellite will provide mobile communication to India through multi-beam coverage
The 1st orbit raising maneuver for GSAT-6A was carried out successfully on 30th March 2018 by firing the Liquid Apogee Motor(LAM) for 2188 seconds from 09:22 AM IST. The 2nd orbit raising maneuver was carried out at 10:00 AM on 31st March 2018. As the satellite was on-course for its 3rd and final orbit raising maneuver on 1st April 2018, Communication was lost with the satellite. Efforts by ISRO are on to re-establish communication with the satellite
> Delhi upgrades to Bharat Stage VI fuel norms, two years before the rest of India
Delhi on Sunday became the first city in the country to implement the highest emission standards Bharat Stage VI for its vehicles. State-owned oil companies began supplying Bharat Stage VI fuel at existing prices at their 391 petrol pumps in the city from Sunday, PTI reported.
In November 2017, when Delhi and neighbouring states experienced dangerous pollution levels, the Centre had decided to advance the implementation of Bharat Stage VI norms in the city by two years to April 1, 2018. The government also asked oil firms to consider introducing the BS-VI norms to other parts of the National Capital Region from April 1, 2019.
India has followed the Bharat Stage IV norms since April 2017, and is scheduled to switch to Bharat Stage VI in April 2020. In January 2016, soon after the Paris climate change conference, the government had decided the country would skip Bharat Stage V norms, and move straight from Bharat Stage IV to Bharat Stage VI four years before the earlier 2024 date.

State-owned Indian Oil Corporation said consumers will not have to pay extra for the cleaner fuel, even though oil companies have invested heavily to produce it. The companies will work on a mechanism to recover their costs after the whole country moves to Bharat Stage VI, said IOC’s Director (Refineries) BV Rama Gopal.
The refineries currently producing the cleaner fuel include those in Mathura, Panipat, Bina and Bhatinda. About Rs 183 crore was spent on the Panipat refinery alone to produce Bharat Stage VI fuel, PTI reported.
> India is ranked 67th for fixed broadband and 109th for mobile internet speeds in February, according to internet speed testing analysis firm Ookla.
"As of February, the Index ranks India 67th for fixed broadband speeds," the firm, which owns Speedtest app, said in a report.
India's performance in fixed broadband download speeds has gone up from average speeds of 18.82 megabit per second (mbps) in November 2017 to20.72 mbps in February 2018; however,it remains below global average download speed of 42.71 mbps, as per the Ookla's Speedtest Global Index.

It draws inspiration from the India's constitutional provision of Article 21, which assures the citizens of India the right to a healthy environment.

The latest grade fuel will help reduce emissions of particulate matter by 10%-20% in existing cars and two-wheelers, but will help even more after vehicles have Bharat Stage VI-compliant engines, Gopal said.
Europe already uses the Euro VI emission norms, while much of India was still covered by BS III norms until the introduction of BS IV this year
> Surat becomes first district to have 100% solar powered health centres
Surat has become the first district in the country to have 100 percent solar powered Primary Health Centers (PHC).
There are a total of 52 PHCs in the district and all of them are now powered by solar system. This initiative will not only bring down the electricity bill by 40 percent but also help fight global warming.
