Chennai, Nov 15: India's latest communication satellite GSAT-29's orbit was successfully raised on Thursday by firing its motors for 4,875 seconds, said the Indian Space Research Organisation (ISRO). 

The first of its scheduled three orbit raising operations was successfully carried out by firing the liquid apogee motor on board the satellite, it said. 

The motor was fired at 8.34 a.m. for one hour and 35 minutes. 

The GSAT-29, which will link Jammu and Kashmir and the northeastern states under the Digital India programme, was put into orbit by India's latest and heaviest rocket geosynchronous satellite launch vehicle (GSLV-Mk III/D2) on Wednesday. 

According to ISRO, after the raising of the orbit, the apogee x perigee was changed from 35,897 km x 189 km to 35,745 km x 7,542 km. 

Apogee refers to the farthest point from the earth and perigee is the closet point to earth in case of a satellite in orbit. 

On Wednesday, ISRO Chairman K. Sivan said the three orbit raising operations would raise the satellite from the geostationary transfer orbit (GTO) to geostationary orbit (GSO). 

The GSAT-29, with a life span of 10 years, is a multi-beam satellite that carries Ka/Ku-band high throughput communication transponders. It was intended to meet the communication requirements of users, especially in remote areas. 

In addition, several new technologies such as Q/V-band payload, data transmission through optical communication link would also be demonstrated helping realise future advanced satellites, Sivan added. 

The Q/V-band payload, data transmission through optical communication link would be used for satellite to satellite communication, said D.K. Das, Director, Space Applications Centre, ISRO. Its frequency is not yet crowded.

The satellite also carries a 55-metre geo-high resolution camera that would be fixed in the weather satellites, once it starts functioning, Sivan said. 

A combination of high throughput satellites -- GSAT-19, GSAT-29, GSAT-11 and GSAT-20 -- would provide the high speed internet needed for the success of the Digital India programme, he added.

Cybercriminals continue to exploit public fear of rising coronavirus cases through malware and phishing emails in the guise of content coming from the Centers for Disease Control and Prevention (CDC) in the US and World Health Organisation (WHO), says cybersecurity firm Kaspersky.

In the APAC region, Kaspersky has detected 93 coronavirus-related malware in Bangladesh, 53 in the Philippines, 40 in China, 23 in Vietnam, 22 in India and 20 in Malaysia. 

Single-digit detections were monitored in Singapore, Japan, Indonesia, Hong Kong, Myanmar, and Thailand. 

Along with the consistent increase of 2019 coronavirus cases comes the incessant techniques cybercriminals are using to prey on public panic amidst the global epidemic, the company said in a statement. 

Kaspersky also detected emails offering products such as masks, and then the topic became more commonly used in Nigerian spam emails. Researchers also found scam emails with phishing links and malicious attachments.

One of the latest spam campaigns mimics the World Health Organisation (WHO), showing how cybercriminals recognise and are capitalising on the important role WHO has in providing trustworthy information about the coronavirus.

"We would encourage companies to be particularly vigilant at this time, and ensure employees who are working at home exercise caution. 

"Businesses should communicate clearly with workers to ensure they are aware of the risks, and do everything they can to secure remote access for those self-isolating or working from home," commented David Emm, principal security researcher.

Some malicious files are spread via email. 

For example, an Excel file distributed via email under the guise of a list of coronavirus victims allegedly sent from the World Health Organisation (WHO) was, in fact, a Trojan-Downloader, which secretly downloads and installs another malicious file. 

This second file was a Trojan-Spy designed to gather various data, including passwords, from the infected device and send it to the attacker.

San Francisco, Mar 18: Facebook said a bug in its anti-spam system temporarily blocked the publication of links to news stories about the coronavirus. Guy Rosen, Facebook's vice president of integrity, said on Twitter Tuesday that the company was working on a fix for the problem.

Users complained that links to news stories about school closings and other information related to the virus outbreak were blocked by the company's automated system.

Later on Tuesday, Rosen tweeted that Facebook had restored all the incorrectly deleted posts, which also covered topics beyond the coronavirus.

Rosen said the problems were unrelated to any changes in Facebook's content-moderator workforce. The company reportedly sent its human moderators home this week because of the coronavirus outbreak.

A representative for Facebook did not immediately respond to questions on the status of Facebook's content moderators, many of whom do not work directly for the company and are not always able to work from home.

Mumbai, Jun 12: Following an overwhelming response for the mega rights issue of Mukesh Ambani-owned Reliance Industries, the partly paid-up rights shares are set to debut on stock exchanges on June 15.

The biggest ever Rs 53,124 crore rights issue was subscribed 1.59 times and received bids worth Rs 84,000 crore on June 3.

Reliance said the rights issue saw a huge investor interest, including from lakhs of small investors and thousands of institutional investors, both Indian and foreign.

In 2019, Ambani said in the Reliance's annual general meeting that the company will be net zero debt by March 2021. The company is on course to achieve its target ahead of the deadline.

"In spite of the COVID-19 crisis and the lockdowns, the due-diligence by Saudi Aramco for the planned investment in the O2C business is on track as both the parties are committed and actively engaged," he said recently.

"With a strong visibility to these equity infusions, Reliance is set to achieve net zero debt status ahead of its own aggressive timeline. We believe rights issue was a part of the company's strategy of deleveraging its balance sheet," said Ambani.
