ISRO launches third navigation satellite

October 16, 2014

Sriharikota (AP), Oct 16: Scripting another success in India's space programme, ISRO today launched its third navigation satellite IRNSS 1C on board its PSLV rocket from here in the wee hours, moving closer to setting up its own navigation system on par with the GPS of the US.

IRNSS 1C is part of the series of seven satellites Indian Space Research Organisation (ISRO) is planning to launch to put in place what is called the Indian Regional Navigation Satellite System. Today's launch marked the first time that India has conducted four orbital launches in a year.

Lifting off from the First Launch Pad of the spaceport exactly at 1.32 AM, the rocket painted a golden brush of flames in the night sky and 20 minutes later successfully placed the 1,425.4 kg weighing satellite in the intended orbit.

ISRO had aimed to launch the satellite into a sub-Geosynchronous Transfer Orbit with a 284 km perigee (nearest point to Earth) and 20,650 km apogee (farthest point to Earth) with an inclination of 17.86 degree with respect to the equatorial plane.

"PSLV C26 has precisely placed IRNSS 1C in its orbit," ISRO Chairman K Radhakrishnan said, describing the successful launch.

Being developed by India, IRNSS is designed to provide accurate position information service to users in the country as well as the region extending up to 1,500 km from its boundary, which is its primary service area.

The IRNSS system, which would ultimately have seven satellites and ground stations, was targeted to be completed by 2015 at a total cost of Rs 1420 crores, ISRO sources said.

Present in the Mission Control Room was Minister of State for Science and Technology Jitendra Singh, who congratulated the scientists on the successful launch.

"I thank you for making me witness this historic moment. As India moves forward to become a world leader, I am sure in the 21 century, any leadership role should be based on scientific foundation and I am glad in the area of space we have emerged as world leaders," he said.

This was the seventh time ISRO was using an XL version of the PSLV rocket for its missions.

The mission life of the satellite is 10 years. The launch of PSLV 26 carrying IRNSS 1C was actually scheduled on October 10 but the countdown was postponed following some technical reasons.

The fully deployed IRNSS system would consist of three satellites in geostationary orbit and four in inclined geosynchronous orbit, about 36,000 km altitude above the earth.

The first two satellites in the series -- IRNSS 1A and IRNSS 1B were launched in July last year and April this year respectively.

With GSAT-14 launched in January, IRNSS-1B in April and SPOT-7 in June, today's was the fourth orbital launch this year.

The IRNSS navigational system would provide two types of services -- Standard Positioning Service, which is provided to all the users and Restricted Service, which is an encrypted service provided only to the authorised users.

IRNSS' applications include terrestrial and marine navigation, disaster management, vehicle tracking and fleet management, navigation aide for hikers and travellers, visual and voice navigation for drivers.

While India is developing its navigation system, a select group of countries have their own navigation systems -- Russia's Global Orbiting Navigation Satellite System (GLONASS), United States' Global Positioning System (GPS), European Union's Galileo (GNSS), China's BeiDou Satellite Navigation System and Japan's Quasi-Zenith Satellite System.

The ISRO chairman also said GSLV Mark III, one of Indian Space Research Organisation's biggest projects this year, which would test India's ability to launch four plus ton payload, would be launched within the next 45 days.

"After GSLV Mark III launch, we have GSAT 16 launch from French Guyana, which will carry 48 transponders. Next is the launch of IRNSS 1D in December," he added.

New Delhi: School-going children are picking up drug and smoking habits and engaging in consumption of alcohol, with the average age of introduction to such harmful substances found to be around 13 years, suggesting a need for earlier interventions as early as primary school, a multi-city survey by AIIMS-Delhi said.

The findings also showed substance use increased in higher grades, with grade XI/XII students two times more likely to report use of substances when compared with grade VIII students. This emphasised the importance of continued prevention and intervention through middle and high school.

The study led by Dr Anju Dhawan of AIIMS's National Drug Dependence Treatment Centre, published in the National Medical Journal of India this month, looks at adolescent substance use across diverse regions.

The survey included 5,920 students from classes 8, 9, 11 and 12 in urban government, private and rural schools across 10 cities -- Bengaluru, Chandigarh, Delhi, Dibrugarh, Hyderabad, Imphal, Jammu, Lucknow, Mumbai, and Ranchi. The data were collected between May 2018 and June 2019.

The average age of initiation for any substance was 12.9 (2.8) years. It was lowest for inhalants (11.3 years) followed by heroin (12.3 years) and opioid pharmaceuticals (without prescription; 12.5 years).

Overall, 15.1 per cent of participants reported lifetime use, 10.3 per cent reported past year use, and 7.2 per cent reported use in the past month of any substance, the study found.

The most common substances used in the past year, after tobacco (4 per cent) and alcohol (3.8 per cent), were opioids (2.8 per cent), followed by cannabis (2 per cent) and inhalants (1.9 per cent). Use of non-prescribed pharmaceutical opioids was most common among opioid users (90.2 per cent).

On being asked, 'Do you think this substance is easily available for a person of your age' separately for each substance category, nearly half the students (46.3 per cent) endorsed that tobacco products and more than one-third of the students (36.5 per cent) agreed that a person of their age can easily procure alcohol products.

Similarly, for Bhang (21.9 per cent), ganja/charas (16.1 per cent), inhalants (15.2 per cent), sedatives (13.7 per cent), opium and heroin (10 per cent each), the students endorsed that these can be easily procured.

About 95 per cent of the children, irrespective of their grade, agreed with the statement that 'drug use is harmful'.

The rates of substance use (any) among boys were significantly higher than those of girls for substance use (ever), use in the past year and use in the past 30 days. Compared to grade VIII students, grade IX students were more likely, and grade XI/XII students were twice as likely to have used any substance (ever).

The likelihood of past-year use of any substance was also higher for grade IX students and for grade XI/XII students as compared to grade VIII students.

About 40 per cent of students mentioned that they had a family member who used tobacco or alcohol each. The use of cannabis (any product) and opioid (any product) by a family member was reported by 8.2 per cent and 3.9 per cent of students, respectively, while the use of other substances, such as inhalants/sedatives by family was 2-3 per cent, the study found.

A relatively smaller percentage of students reported use of tobacco or alcohol among peers as compared to among family members, while a higher percentage reported inhalants, sedatives, cannabis or opioid use among peers.

Children using substances (past year) compared to non-users reported significantly higher any substance use by their family members and peers.

There were 25.7 per cent students who replied 'yes' to the question 'conflicts/fights often occur in your family'. Most students also replied affirmatively to 'family members are aware of how their time is being spent' and 'damily members are aware of with whom they spend their time'.

New Delhi: IndiGo, India’s largest airline, faced major operational turbulence this week after failing to prepare for new pilot-fatigue regulations issued by the Directorate General of Civil Aviation (DGCA). The stricter rules—designed to improve flight safety—took effect in phases through 2024, with the latest implementation on November 1. IndiGo has acknowledged that inadequate roster planning led to widespread cancellations and delays.

Below are the key DGCA rules that affected IndiGo’s operations:

1. Longer Mandatory Weekly Rest

Weekly rest for pilots has been increased from 36 hours to 48 hours.

The government says the extended break is essential to curb cumulative fatigue. This rule remains in force despite the current crisis.

2. Cap on Night Landings

Pilots can now perform only two night landings per week—a steep reduction from the earlier limit of six.

Night hours, defined as midnight to early morning, are considered the least alert period for pilots.

Given the disruptions, this rule has been temporarily relaxed for IndiGo until February 10.

3. Reduced Maximum Night Flight Duty

Flight duty that stretches into the night is now capped at 10 hours.

This measure has also been kept on hold for IndiGo until February 10 to stabilize operations.

4. Weekly Rest Cannot Be Replaced With Personal Leave

Airlines can no longer count a pilot’s personal leave as part of the mandatory 48-hour rest.

Pilots say this closes a loophole that previously reduced actual rest time.

Currently, all airlines are exempt from this rule to normalise travel.

5. Mandatory Fatigue Monitoring

Airlines must submit quarterly fatigue reports along with corrective actions to DGCA.

This system aims to create a transparent fatigue-tracking framework across the industry.

The DGCA has stressed that these rules were crafted to strengthen flight safety and align India with global fatigue-management standards. The temporary relaxations are expected to remain until February 2025, giving IndiGo time to stabilise its schedules and restore normal air travel.

The deletion of over 58 lakh names from West Bengal’s draft electoral rolls following a Special Intensive Revision (SIR) has sparked widespread concern and is likely to deepen political tensions in the poll-bound state.

According to the Election Commission, the revision exercise has identified 24 lakh voters as deceased, 19 lakh as relocated, 12 lakh as missing, and 1.3 lakh as duplicate entries. The draft list, published after the completion of the first phase of SIR, aims to remove errors and duplication from the electoral rolls.

However, the scale of deletions has raised fears that a large number of eligible voters may have been wrongly excluded. The Election Commission has said that individuals whose names are missing can file objections and seek corrections. The final voter list is scheduled to be published in February next year, after which the Assembly election announcement is expected. Notably, the last Special Intensive Revision in Bengal was conducted in 2002.

The development has intensified the political row over the SIR process. Chief Minister Mamata Banerjee and her Trinamool Congress have strongly opposed the exercise, accusing the Centre and the Election Commission of attempting to disenfranchise lakhs of voters ahead of the elections.

Addressing a rally in Krishnanagar earlier this month, Banerjee urged people to protest if their names were removed from the voter list, alleging intimidation during elections and warning of serious consequences if voting rights were taken away.

The BJP, meanwhile, has defended the revision and accused the Trinamool Congress of politicising the issue to protect what it claims is an illegal voter base. Leader of the Opposition Suvendu Adhikari alleged that the ruling party fears losing power due to the removal of deceased, fake, and illegal voters.

The controversy comes amid earlier allegations by the Trinamool Congress that excessive work pressure during the SIR led to the deaths by suicide of some Booth Level Officers (BLOs), for which the party blamed the Election Commission. With the draft list now out, another round of political confrontation appears imminent.

As objections begin to be filed, the focus will be on whether the correction mechanism is accessible, transparent, and timely—critical factors in ensuring that no eligible voter is denied their democratic right ahead of a crucial election.
