Satellite surveillance system installed in 21 airports

November 21, 2013

SatelliteTiruchirappalli (TN), Nov 21: A cost effective satellite-based surveillance system has been installed in 21 airports in the country to help controllers track aircraft more accurately and enhance air space capacity.

The ADS-B system will help controllers track aircraft more accurately and thereby reduce spacing between two aircraft and enhance air space capacity, V Somasundaram, Board Member (Air Navigation Services), AAI, told reporters here last evening.

The new system will give alert every second as against the 5 seconds alert in the conventional approach radar. Approach radars currently cost Rs 10 crore while ADS-B costs only one tenth of this, he said.

Already, 21 stations have been covered and all the 120 airports under the ambit of Airports Authority of India, would be covered within the next one year in a phased manner.

The new system at Trichy International Airport will be commissioned within the next one month. The swath area of Trichy system is about 250-300 air km. As a result, Madurai does not require such a system, he said.

The data generated by ADS-B will be monitored through integrated air space management system at Chennai and Tiruvananthapuram.

On the long pending commissioning of GAGAN (Geo Augmented Navigation System) in the country, Somasundaram said this will hopefully be commissioned by December end pending initial clearance from DGCA.

The test run will take place and DGCA is expected to give its full clearance by June-July next, he added.

New Delhi, Jun 15: Average temperature of India experienced a rise of 0.7 degree Celsius, along with decline in rainfall, significant increase in frequency of very severe cyclonic storms and droughts in over a decade due to human activities, the Ministry of Earth Sciences in its research report said.

The contentions were made in a report issued by the ministry on the impact of climate change. It will be published by Union Minister Harsh Vardhan on June 19.

According to the report, "Since the middle of the twentieth century, India witnessed rise in temperature; decrease in monsoon; rise in extreme temperature and rainfall, droughts, and sea levels; and increase intensity of severe cyclones.

The report, prepared by researchers of the Centre for Climate Change Research, a cell under The Ministry's Indian Institute of Tropical Meteorology, Pune, further stated that there is compelling scientific evidence that human activities have influenced these changes in regional climate.

India's average temperature has risen by around 0.7 degrees Celsius during 1901-2018, it said, adding that the rise is largely on account of GHG-induced warming and partially offset by forcing due to anthropogenic aerosols.

It states that the average temperature over India is projected to rise by 4.4 degrees Celsius, while the intensity of heat waves is likely to increase by 3-4 times by the end of the century.

In the 30-year period between 1986 and 2015, temperatures of the warmest day and the coldest night of the year have risen by about 0.63 degrees Celsius and 0.4 degree Celsius.

According to the report, by the end of the century, the temperatures of the warmest day and the coldest night are projected to rise by approximately 4.7 degrees Celsius and 5.5 degrees Celsius, respectively.

Alarmingly, sea surface temperature of the tropical Indian Ocean has also risen by one degrees Celsius on average during 1951-2015.

"The frequency of very severe cyclonic storms during the post-monsoon season has increased significantly (+1 event per decade) during the last two decades (2000-2018)," it added.

This came in the backdrop of Cyclone 'Amphan' and 'Nisarga' which made landfalls on May 20 and June 3 and killed several people, flattened villages, and destroyed farms.

"This is the first-ever climate change assessment report for India. This report will be very useful for policy makers, researchers, social scientists, economists, and students," said M. Rajeevan, secretary, the Ministry of Earth Sciences.

Besides this, the report also highlighted various other unnerving data on climate change in the country. Both the frequency and extent of droughts have increased significantly during 1951-2016.

The overall decrease of seasonal "summer monsoon rainfall" during the last 6-7 decades has led to an increased propensity for droughts over India.

"In particular, areas over central India, southwest coast, southern peninsula and north-eastern India have experienced more than 2 droughts per decade, on average, during this period. The area affected by drought has also increased by 1.3 per cent per decade over the same period."

The Hindu Kush Himalayas (HKH) also experienced a temperature rise of about 1.3 degree Celsius during 1951-2014.

Several areas of the Himalayas have experienced a declining trend in snowfall and also retreat of glaciers in recent decades. By the end of the twenty-first century, its annual mean surface temperature is projected to increase by about 5.2 degree Celsius.

The summer monsoon precipitation from June to September over India has also declined by around 6 per cent from 1951 to 2015, with notable decreases over the Indo-Gangetic Plains and the Western Ghats, the report further states.

Jan 31: President Ram Nath Kovind on Friday hailed the contentious Citizenship Amendment Act as "historic" in his address to joint sitting of both houses of Parliament, prompting protests by some opposition members.

He also said that debate and discussion on any issue strengthens democracy while violence during protests weaken it.

"The Citizenship Amendment Act is a historic law. It has fulfilled wishes of our founding fathers including Mahatma Gandhi," he said.

"Debate and discussions strengthen democracy, but violence during protests weaken democracy," he said without directly referring to the anti-CAA protests in the country some of which have witnessed violence.

In a reference to abrogation of Article 370, Kovind said there is happiness among people of India that people in Jammu and Kashmir and Ladakh have got rights on par with the rest of the country.

The president said Parliament has created record in the first seven months of the new government headed by Narendra Modi by enacting several landmark legislations.

"My government is taking strong steps for making this decade as India's decade and this century as India's century," he said.
