India's GPS Freebie for Neighbours Soon

With the prestigious Gagan project expected to be rolled out by the civil aviation ministry early this year, India plans to use it as a 'goodwill gift' by offering it to neighbouring countries, as a strategic move to counter China's influence.

Prime minister Narendra Modi recently held meetings with high-ranking officials from Indian Space Research Organisation (Isro) and Airports Authority of India (AAI) to discuss the possibilities of taking the services across the border.


Gagan, which stands for GPS Aided Geo Augmented Navigation, is a satellite-based navigation system which provides autonomous, high precision geo-spatial location information of the user in terms of latitude, longitude and height along with velocity and time. It covers large areas of airspace formerly not served by other navigational aids and its benefits extend beyond aviation — to all modes of transport, including maritime, highways and railroads. Furthermore, it can also be used in surveying, precision farming, more robust localisation monitoring which is expected to provide better control and support to law enforcement agencies and enhanced town-planning management.

The AAI, which is developing the project in collaboration with Isro, later plans to commercialise the service. "Being in the Asia Pacific region, India wants to be a leader in the technology," said CR Sudhir, executive director, Communication Navigation and Surveillance (operation management), which provides infrastructure to Air Traffic Control.

According to AAI officials, Gagan will redefine navigation over Indian region and it may soon be used as the sole means of navigation system, eventually replacing most, if not all, of the costly ground-based infrastructure in the coming years. Once implemented, Gagan would make India only the fifth country in the world to have a similar system after US, Russia, China and the European Union. "What the US is doing presently with 27 satellites, we will be doing with just seven," said AS Ganeshan, programme director, satellite navigation programme, Isro, to a gathering of aviation industry insiders during a seminar held recently in Bengaluru to discuss indigenisation of air navigation infrastructure in India.

The system is currently being pilot tested in Chennai airspace and will be extended to the entire Indian region, once it gets the approval from aviation regulator Directorate General of Civil Aviation (DGCA). A master control room has been set up in Bengaluru while 15 reference stations have been constructed across different locations of the country which collect measurement data and broadcast message from all the GPS and GEO satellites in view and forward them to the control centre.

The importance of the project for non-aviation benefits can be gauged from the fact that the Indian Railways has tied up with Isro to help it in developing technologies for anti-collision and other uses. In a meeting held on December 16, Railway minister Suresh Prabhu directed the Railway Board to explore the use of geo-spatial technologies for this purpose. In fact, Konkan railways, which passes through tough terrains, has approached Isro separately for the same, said the senior bureaucrats involved in the development of the project. "General managers should think of new and innovative methods to reduce accidents and make railway operations safer," Prabhu said referring to the new initiative during a conference on December 30.

The deaths at unmanned level crossings is another problem of the railways. Railway ministry officials said by imbibing the latest satellite technologies, an alert message will be flashed automatically in the mobile phones of all the road users who are in the vicinity of an Unmanned Level Crossing (UMLC) about the approaching train. Insiders in the ministry claim that with the use of such technologies, accidents at UMLCs may be minimised/controlled to a large extent.

Gagan's operational benefits (Aviation)
>>Provides opportunity to cover very large areas of airspace
>>Increases capability, flexibility and it's a cost-effective navigation option than the ground-based navigation aids
>>Offers higher safety and seamless transition between different areas
>>Provides for reduction in fuel consumption

Gagan's operational benefits (non-aviation)
>>Benefits extend beyond aviation to all modes of transportation, including maritime, highways and railroads
>>Benefits also extend to applications such as surveying, precision farming, mobile applications
More robust localisation and monitoring enables better control and support to law-enforcement agencies

Limitaion of current technology
>>Stand alone GPS/Glonass cannot satisfy the integrity, accuracy and availability requirements of all phase of flight, particularly for the more stringent precision approaches
>>Integrity is not guaranteed since all satellites may not be satisfactorily working all the time
>>Time to alarm could be from minutes to hours and there is no indication of quality of service
>>Accuracy is not sufficient. The vertical accuracy for 95% of the time is less than 10 meters
>>For GPS/Glonass standalone systems availability and continuity are not assured

Navigational satellite systems in operation
>>Global Positioning System (GPS) of USA
>>Global Navigation Satellite System (Glonass) of Russia

India to have its own version of GPS in 2015

The GPS is a space-based satellite navigation system managed by the United States that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is freely accessible to anyone with a GPS receiver.

“We will be completing the IRNSS (Indian Regional Satellite Navigation System) constellation by launching four more satellites and operationalise the navigation system," outgoing Isro chairman Dr K Radhakrishnan told HT. “ The requirement of such a navigation system is needed because access to foreign government-controlled global navigation satellite systems can be restricted and become disturbed in hostile situations. The IRNSS would provide two services, with the Standard Positioning Service open for civilian use and the Restricted Service, encrypted one, for authorised users (military).”

Maintaining that satellite navigation was a domain that was constantly evolving he said: “ Our Indian Regional Navigation Satellite System will be a regional system, dedicated for usage in Indian Main land and 1500 km around. Initially it would be a constellation of 7 Satellites at an altitude of 36,000 km, distributed in geostationary and inclined orbits. The accuracy is expected to be 10-20 meters depending on the application.”

With this India will join a select group of countries including US, China and Russia who have their navigational system. Russia had recently launched a new generation Glonass-K navigation satellite.

Besides the completion of IRNSS series, Dr Radhakrishnan said there were many other important launches lined up for next year: “ There would be a launch of GSAT 6 using GSLV, launch of ASTROSAT using PSLV and launch of a heavy communication satellite GSAT 15 carrying 24 Ku band transponders.”

Commercial launch of a few foreign satellites including three UK satellites are targeted for January 2015 to March 2016, he said.

Among other things, ground testing of high power cryogenic engine for LVM 3(GSLV Mk III) for development of advanced communication satellites, remote sensing satellites and Indian lander would be progressing all through 2015.

“Research and development, technical infrastructure development would continue next year. Enhancing space applications would be an important target for the coming months”

Do the neighbouring countries really want this and will they appreciate it?

Pakistanis like @RiazHaq may say why is India spending so much on satellites when they dont have toilets

Bangladeshis like @idune will like this to be a rawamy conspiracy to control and monitor bangladeshi traffic

SriLankans like @manlion will say this is a plot to stiffle the tamils

It seems that it can be used upto Africa to Australia also. It is nice to read that they manage the same with only 7 satellite against 21 of US.

 

[jha]

First let Indians try this. Always talking big.

 

[vsdave2302]

Allow it to be used by Myanmar, Indonesia and vietnam also.

 

[Donatello]

What's the point of this? GPS is already openly available.....and in times of war, i doubt if any of the 'Indian Neighbors' are going to trust the Indian system anyway.

Those seven satellites are of IRNSS which is alltogather another autonomous regional navigation system like the GPS - GAGAN is based on just three satellites - GSAT-8, GSAT-10 and the recently launched GSAT-15 the rest is all controlled by some 15 Indian Reference Stations, 3 Indian Navigation Land Uplink Stations, 3 Indian Mission Control Centers, and all other associated software and communication links installed. I think the Journalist mixed up GNSS and SBAS that is GAGAN and IRNSS - both of them are different.

First let Indians try this. Always talking big.

We are! In 2014, the Directorate General of Civil Aviation (DGCA), India provisionally certified the GPS Aided Geo Augmented Navigation (GAGAN) system to RNP0.1 (Required Navigation Performance, 0.1 Nautical Mile) service level. The certification enabled aircraft fitted with SBAS equipment to use GAGAN signal in space for navigation purposes.

In 2009, Raytheon had won an 82 million dollar contract. It was mainly dedicated to modernize Indian air navigation system. The vice president of Command & Control Systems, Raytheon Network Centric Systems, Andy Zogg commented:

“GAGAN will be the world’s most advanced air navigation system and further reinforces India’s leadership in the forefront of air navigation. GAGAN will greatly improve safety, reduce congestion and enhance communications to meet India’s growing air traffic management needs”

Raytheon Wins $82M Air Navigation Contract From India

In 2012, the Defence Research and Development Organisation received a "miniaturised version" of the device with all the features from global positioning systems (GPS) and global navigation satellite systems (GNSS). The module weighing just 17 gm, can be used in multiple platforms ranging from aircraft (e.g. winged or rotor-craft) to small boats, ships. Reportedly, it can also assist "survey applications". It is a cost-efficient device and can be of "tremendous" civilian use. The navigation output is composed of GPS, GLONASS and GPS+GLONASS position, speed and time data. According to a statement released by the DRDO, G3oM is a state-of-the-art technology receiver, integrating Indian GAGAN as well as both global positioning system and GLONASS systems

http://www.deccanchronicle.com/channels/nation/south/17-gm-device-guide-missiles-968

We have also developed a flight-management system based on GAGAN will then be poised to save operators time and money by managing climb, descent and engine performance profiles. The FMS will improve the efficiency and flexibility by increasing the use of operator-preferred trajectories. It will improve airport and airspace access in all weather conditions, and the ability to meet the environmental and obstacle clearance constraints. It will also enhance reliability and reduce delays by defining more precise terminal area procedures that feature parallel routes and environmentally optimised airspace corridors.

• GAGAN will increase safety by using a three-diemensional approach operation with course guidance to the runway, which will reduce the risk of controlled flight into terrain i.e., an accident whereby an airworthy aircraft, under pilot control, inadvertently flies into terrain, an obstacle, or water.

• GAGAN will also offer high position accuracies over a wide geographical area like the Indian airspace. These positions accuracies will be simultaneously available to 80 civilian and more than 200 non-civilian airports and airfields and will facilitate an increase in the number of airports to 500 as planned. These position accuracies can be further enhanced with ground based augmentation system.

Yes,

Glonas work under GPS and increases the accuracy. While INRSS in itself is a GPS type ststem with limited geographical coverage.

Pakistan can already use GPS and BEIDOU........so frankly no one gives a crap.

GNSS and SBAS - both of them are different things altogether - GPS and COMPASS/BEIDOU which Pakistan will be using are global navigation satellite systems (GNSS) NOT satellite-based augmentation systems (SBAS). SBAS refers to the Augmentation of a global navigation satellite system (GNSS) - a method of improving the navigation system's attributes, such as accuracy, reliability, and availability, through the integration of external information into the calculation process. Pakistan or any other country in the subcontinent for that matter doesn't have access to SBAS. India is offering its SBAS GAGAN to it's neighbors, not its GNSS that is IRNSS.

These are the SBAS around the globe-

>>The Wide Area Augmentation System (WAAS), operated by the United States Federal Aviation Administration (FAA).
>>The European Geostationary Navigation Overlay Service (EGNOS), operated by the European Space Agency.
>>The Multi-functional Satellite Augmentation System (MSAS) system, operated by Japan's Ministry of Land, >>Infrastructure and Transport Japan Civil Aviation Bureau (JCAB).
>>The Quasi-Zenith Satellite System (QZSS), proposed by Japan.
>>The GPS Aided Geo Augmented Navigation (GAGAN) system being operatlonalized by India.
>>The GLONASS System for Differential Correction and Monitoring (SDCM), proposed by Russia.
>>The Satellite Navigation Augmentation System (SNAS), proposed by China.
>>The Wide Area GPS Enhancement (WAGE), operated by the United States Department of Defense for use by military and authorized receivers.

GAGAN is compatible with other SBAS systems such as the Wide Area Augmentation System (WAAS), the European Geostationary Navigation Overlay Service (EGNOS) and the Multi-functional Satellite Augmentation System (MSAS) and will provide seamless air navigation service across regional boundaries.

Modi's policy of "appeasing" muslims in Kashmir or in neighbouring nations, is a bad idea. Its same old failed Hajpayean doctrine he is repeating. Ask everybody to pay, otherwise ask them to f*ck off. BD and PAK are already sitting on Hindu land taken in 1947, which contain minerals too.

Is india getting those minerals for free, without paying $? No. So it doesn't make sense why indian resources(be it air or water) should be given freely to them, while charging local indian consumers for same. This is like doing all heavy-lifting urself and throwing out fruits for free due to emotional dogmas of over-aged Modi.

Acctual muslim Vote bank is a great temption for all politicians because you do not need to deliver them anything but Just to create a fear of other and satisfy their egoist+feared mentality. Congress exploited that to rule country for years. I am not very surprised if Modi is as a politician have an eye on Muslims who are very easy to cheat.

That's utter BS.....in this day and age of globalization, self sufficiency doesn't mean everything has to be done in house even if comparing solutions are available........and sometimes i may not be practical.
You define you requirements and you go about achieving them.

About the Indian GPS, it is fine if India wants to do it, but i don't see it becoming anything important in India or beyond anytime soon when there are time tested systems easily available.

It's same as India launching a satellite to Mars, it is good for the ego boost....but then what did exactly India learn that is already not known to the world?

We want new solutions, not reinventing the old ones.

Bitch Please! You still don't have any idea of what you are talking about! Yet again you failed to understand the difference between the two - India didn't have any access to any of the the SBAS or rather there wasn't any SBAS operational in the most of the Asia-Pacific and the subcontinent in particular. There isn't any "time tested system easily available" in the subcontinent that may cater to the needs fulfilled by a SBAS - it isn't a choice - it's a necessity. Ever wondered why there is only one GPS and nine SBAS based on it?

Please tell that to the team that Procures India's first line Airforce equipment.

Nice joke.

We don't "borrow" - we "buy" unlike one of our neighbor which survives on foreign aid - that's where the difference lies.

Poor comprehension skills by the way.
