28-hour countdown for ISRO's record satellite launch begins

February 14, 2017

Chennai, Feb 14: The 28-hour countdown for the launch of a record 104 satellites by India on board a single rocket from the spaceport of Sriharikota, about 125 km from here, commenced today.

India will become the first country to script history if it succeeds in launching the 104 satellites in a single rocket.

The countdown for the launch of PSLV-C37/Cartosat2 Series satellite mission began at 5:28 AM soon after the Mission Readiness Review committee and Launch Authorisation Board gave its approval for lift off, Indian Space Research Organisation (ISRO) said.

Scientists have commenced filling of the propellant for the rocket, it said.

The space agency's trusted workhorse Polar Satellite Launch Vehicle PSLV-C37, on its 39th mission, would launch a record 104 satellites belonging to international customers.

What is significant about the launch is the number of satellites carried by a rocket. Compared to successful launch by the Russian Space Agency launching 37 satellites in one go, India will become the first country to script history if it succeeds in launching 104 satellites in a single rocket.

It will also be ISRO's second successful attempt after launching 23 satellites in one go in June 2015.

PSLV will first launch the 714 kg CARTOSAT-2 Series satellite for earth observation and then inject 103 co-passenger satellites, together weighing about 664 kg at lift-off into polar Sun Synchronous Orbit, about 520 km from Earth.

ISRO scientists have used the XL Variant -- the most powerful rocket -- earlier used in the ambitious Chandrayaan and during the Mars Orbiter Mission (MOM).

Of 101 co-passenger satellites, 96 belong to USA, five from International customers of ISRO -- Israel, Kazakhstan, Netherlands, Switzerland, United Arab Emirates, respectively.

Two other Indian nano satellites, totally weighing about 1,378 kg, will also ride piggyback in the rocket

The nano-satellites belonging to international customers are being launched as part of the arrangement by Antrix Corporation Ltd (ANTRIX) the commercial arm of the ISRO.

Cartosat-2 Series, which is the primary satellite, will be similar to the earlier four satellites in Cartosat-2 Series.

After coming into operation, it will provide remote sensing services.Images sent by it will be useful for coastal land use and regulation, road network monitoring, distribution of water and creation of land use maps, among others.

Cartosat-2 Series has a mission life of five years.

The two Indian Nano-satellites INS-1A and INS-1B were developed as co-passenger satellites to accompany bigger satellites on PSLV.

The primary objective of INS (ISRO Nano Satellite) is to provide an opportunity for ISRO technology demonstration payloads, provide a standard bus for launch on demand services.

INS-1A carries Surface Bidirectional Reflectance Distribution Function Radiometer and INS-1B caries Earth Exosphere Lyman Alpha Analyser as payloads.

The Brazilian government said that the Amazon rainforest witnessed deforestation of a record 829 sq km in May, the highest monthly level since 2015.

On Friday, the National Institute for Space Research (INPE) said that deforestation in the Amazon increased by 91 sq km compared to the same period last year, reports Xinhua news agency.

Between January and April, destruction of the forest by illegal loggers and ranchers rose 55 per cent, or a total of 1,202 sq km was wiped out, it said.

The Real-time Deforestation Detection system, a federal project created to monitor human activity in the Amazon, alerted authorities to the increase in the rate of destruction of the rainforest.

A recent study by the Amazon Environmental Research Institute (IPAM) warned that deforestation in 2020 could reach 11,900 sq km if the pace of May, June, and July follows the historical average.

Deforestation in the region has soared since President Jair Bolsonaro took office last year, according to conservation groups.

He has argued that more farming and mining in protected areas of the forest were the only way to lift the region out of poverty.

Bolsonaro's environmental policies have been widely condemned but he has rejected the criticism, saying Brazil remains an example for conservation.

Thiruvananthapuram, Mar 12: In the wake of COVID-19 outbreak, Internet service providers in Kerala have agreed to step up the network capacity by 30 to 40 per cent of the present capacity to meet the demand, especially in view of the spurt in work-at-home mode.

"The decision was made at a meeting of representatives of various telecom service providers in Kerala circle and officials of the Telecommunication Department convened by the Secretary, Electronics and IT, following a direction by Chief Minister Pinarayi Vijayan to look into the issue," said a press release by the IT Department.

The decision will be beneficial for those working in IT institutions. The government has come out with a set of suggestions to avoid social gatherings at public places in view of coronavirus spread. Telecom service providers have assured the government that they are well equipped to face the current situation.

The major part of Internet consumption in Kerala is made available through local servers. Moreover, global Internet traffic is very low as compared to the overall consumption. So, increasing the capacity won't be difficult, service providers informed.

"Complaints regarding the low availability of the Internet due to the spurt in consumption of the Internet can be made to the service providers to their complaint redressal number or inform state government call centre (155300). But complaints regarding the insufficiency in the current network infrastructure should be strictly avoided," said the release.

The IT Department will also demand daily reports from various telecom service providers. By analysing these reports, steps for remedies will be taken after bringing the sudden increase in consumption to the service providers.

Due to impacts of COVID-19, shipments of total mobile phones are forecast to decline 14.6% in 2020, while smartphone shipments will achieve a slightly slower decline of 13.7 % year over year to total 1.3 billion units this year, according to a Gartner forecast on Tuesday.

"While users have increased the use of their mobile phones to communicate with colleagues, work partners, friends and families during lockdowns, reduced disposable income will result in fewer consumers upgrading their phones," Ranjit Atwal, Senior Research Director at Gartner, said in a statement.

"As a result, phone lifetimes will extend from 2.5 years in 2018 to 2.7 years in 2020," said Atwal.

In 2020, affordable 5G phones were expected to be the catalyst to increase phone replacements, but now it is unlikely to be the case.

5G phones are now forecast to represent only 11% of total mobile phone shipments in 2020.

"The delayed delivery of some 5G flagship phones is an ongoing issue," said Annette Zimmermann, Research Vice President at Gartner.

"Moreover, the lack of 5G geographical coverage along with the increasing cost of the 5G phone contract will impact the choice of a 5G phone."

Overall, spending on 5G phones will be impacted in most regions apart from China, where continued investment in 5G infrastructure is expected, allowing providers in China to effectively market 5G phones.

The combined global shipments PCs, tablets and mobile phones are on pace to decline 13.6% in 2020, according to the forecast.

PC shipments are expected to decline 10.5% this year. Shipments of notebooks, tablets and Chromebooks are forecast to decline slower than the PC market overall in 2020.

"The forecasted decline in the PC market in particular could have been much worse," said Atwal.

"However, government lockdowns due to COVID-19 forced businesses and schools to enable millions of people to work from home and increase spending on new notebooks, Chromebooks and tablets for those workers. Education and government establishments also increased spending on those devices to facilitate e-learning."

Gartner said that 48 per cent of employees will likely work remotely at least part of the time after the COVID-19 pandemic, compared to 30 % pre-pandemic.

Overall, the work from home trend will make IT departments shift to more notebooks, tablets and Chrome devices for work.

"This trend combined with businesses required to create flexible business continuity plans will make business notebooks displace desk based PCs through 2021 and 2022," said Atwal.
