India to launch satellite-based navigation system GAGAN


A satellite-based navigation system to aid air traffic from Southeast Asia to Africa, including over the high seas in the vast region, would be launched tomorrow, placing India into a select group of nations which possess such a sophisticated technology. GAGAN or the GPS Aided Geo Augmented Navigation to be launched by Civil Aviation Minister Praful Patel would not only help the civil aviation sector but also help in marine navigation, search and rescue operations, rail and road transport, survey and mapping as well as precision farming.

So far, only the US, Europe and Japan have developed similar capabilities.:cheers: GAGAN would fill the gap between the European EGNOS and the Japanese MSAS systems to provide seamless air navigation service across regional boundaries, an official spokesperson said.

The system, developed jointly by the Indian Space Research Organisation and Airports Authority of India, would operationalise a satellite-based Indian Flight Information Region in conjunction with all nations from Southeast Asia, Gulf and West Asia and the eastern coast of Africa.

It would be based on a satellite constellation consisting of 24 satellites positioned in six earth-centered orbital planes, she said.:cheers:

When commissioned, GAGAN is expected to provide civil aeronautical navigation signals consistent with International Civil Aviation Organization (ICAO) standards based on the Global Navigation Satellite System (GNSS) Panel, as part of the Future Air Navigation System for the aviation sector.

GAGAN would benefit the sector in a major way, including enabling aircraft to fly on direct straight-line routes.

Currently, the planes fly over the land-based radars which are not installed in a straight line. GAGAN would help them navigate on a straight line as it is dependent on satellite route guidance and thus enhance fuel savings.

The system would help in 'precision approach' while landing at all airports in this vast region.

It would not only result in savings on ground-based radar systems, but also improve air traffic capacity through reduced aircraft separation, that is more planes can be accommodated in a limited airspace.

GAGAN would also enhance air-to-air surveillane and provide minimum safe altitude warning, besides facilities for controlled flight into terrain, the absence of which becomes a major cause for aircrashes while landing.

The project involves establishment of 15 Indian Reference Stations, three Indian Navigation Land Uplink Stations, three Indian Mission Control Centers and installation of all associated softwares and communication links.

Navigation system "GAGAN" to be launched tomorrow

India's GPS Aided Geo Augmented Navigation system (GAGAN) will be launched here tomorrow to make it the fourth country in the world to have a satellite-based navigation system.

The system, which will be launched by Union Civil Aviation Minister Praful Patel, will provide Satellite Based Augmentation System services over India and neighbouring regions, an official press release said.

It said the system would provide enhanced navigation performance for critical applications like civil aviation, marine navigation, tran and road transport, precision farming, search and rescue (SAR) operations, surveying and mapping (geodetic and geodynamic), mining and so on.

According to the release, GAGAN is a Satellite Based Navigation System developed by Airports Authority of India (AAI) and Indian Space Research Organisation (ISRO) to deploy and certify an operational Satellite Based Augmentation System (SBAS) for the Indian Flight Information Region (FIR), with expansion capability to neighbouring FIR.

When commissioned, GAGAN is expected to provide a civil aeronautical navigation signal consistent with International Civil Aviation Organization (ICAO) Standards and Recommended Practices (SARPs) as established by the Global Navigation Satellite System Panel (GNSSP). ICAO has endorsed Global Navigation Satellite System as Future Air Navigation System (FANS) for civil aviation.

The project involves establishment of a full complement of Satellite Based Augmentation System (SBAS) consisting of 15 Indian Reference Stations (INRES), 3 Indian Navigation Land Uplink Stations (INLUS), 3 Indian Mission Control Centers (INMCC), 3 Geo-stationary Navigation payload in C and L bands and with all the associated software and communication links.:cheers:

The Global Positioning System (GPS) is a satellite navigation system designed to provide instantaneous position, velocity and time information anywhere on the globe.

The baseline satellite constellation consists of 24 satellites positioned in six earth-centered orbital planes. The orbital period of a GPS satellite is one-half of a sidereal day or 11 hours 58 minutes. The orbits are nearly circular and equally spaced about the equator at a 60-degree separation with an inclination of 55 degrees relative to the equator. The orbital radius is approximately 26,600 km. With the baseline satellite constellation, users with a clear view of the sky have a minimum of four satellites in view.

The release said the current GPS constellation cannot support requirements for all phases of flight and integrity is not guaranteed. All satellites are not monitored at all times; time-to-alarm is from minutes to hours, and there no indication of quality of service. Further, the accuracy levels are not sufficient, it said.

In the GAGAN system, the Global Navigation Satellite System (GNSS) data is received and processed at widely dispersed INRES which are strategically located to provide coverage over the required service volume. Data is forwarded to the INMCC, which process the data from multiple INRES to determine the differential corrections and residual errors for each monitored satellite and for each predetermined ionospheric grid point (IGP). Information from the INMCC is sent to the INLUS and uplinked along with the GEO navigation message to the GAGAN GEO satellite. The GAGAN GEO satellite downlinks this data to the users via two L-band ranging signal frequencies (L1 and L5), with GPS type modulation, to improve the accuracy and availability and provide integrity.

The release said GAGAN would provide augmentation service for GPS over India, Bay of Bengal, South-East Asia, Middle East expanding upto Africa. :cheers: GAGAN will be compatible and interoperable with other SBAS systems such as the Wide Area Augmentation System (WAAS) of the United States, the European Geostationary Navigation Overlay Service (EGNOS) of European Union (EU) and the Multi-functional Satellite Augmentation System (MSAS) of Japan. It will fill the gap between the European EGNOS and the Japanese MSAS to provide seamless air navigation service across regional boundaries.

GAGAN's benefits for the civil aviation sector would include improved efficiency and economy, direct routes, increased fuel savings, precision approach at all runways, significant cost savings due to withdrawal of ground aids, reduced workload of flight crew and Air Traffic Control towers, improved capacity through reduced aircraft separation, improved safety, Controlled Flight Into Terrain (CFIT), enhanced air-to-air surveillance and availability of Minimum Safe Altitude Warning.

IF ISRO can be trusted with operation of LUT/MCC under the international COSPAS/SARSAT Programme for Search and Rescue. The International Community would Also Trust our Satellites... But Again GAGAN is for Regional Navigation, Wait for GLONASS with Russian Collaboration and Indian Regional Navigational Satellite System is Getting ready and we will be Independent from GPS to an extent

Hey, you win the 'Troll of the Day' award!

Unfortunately this system can't be used to guide idiots. Otherwise you would have had some hope of finding your way out of your delusional world into reality.

CCEA approves one time grant of Rs 378 cr for GAGAN project


The government today approved a one time grant-in aid of Rs 378 crore as Budgetary support for implementation of GPS-aided Geo Augmented Navigation system (GAGAN).

The GAGAN system, estimated to cost Rs 774 crore, would make the skies from South-east Asia to Africa, including Indian airspace, much safer.

The prestigious project, being developed jointly by the Airports Authority of India (AAI) and Indian Space Research Organisation (ISRO), would place India in the fourth position along with the US, Europe and Japan to have such an advanced navigation system.

"The Cabinet Committee on Economic Affairs has approved a one-time grant-in-aid of Rs 378 crore from the Government Budgetary Support (GBS) for implementation of GAGAN project...," an official statement said.

The project is expected to be ready for operational use by May, 2013, it said.

It would be an all weather national infrastructure and can be used by defence services, security agencies, Railways, surface transport, shipping, telecom industry besides personal users of position location based services, it said.

It will provide precision approach to all aircraft either landing at Indian airports or overflying the airspace, even over the high seas.

The system will offer seamless satellite navigation to air traffic across the Indian Ocean region.

As much as Rs 171 crore would be provided for the project for the current year, while for the next year, appropriate provisions would be made for the balance amount, the statement said.

Of the total project cost of Rs 774 crore, AAI was required to shell out Rs 604 crore, while ISRO was to contribute rest of the money (Rs 170 crore).

AAI has already spent Rs 226 crore and sought one time grant-in-aid of Rs 378 crore from the Gross Budgetary Support to meet its balance commitment, the statement said.

After completion of its final operational phase, GAGAN will be compatible with other Space Based Augmentation Systems like the Wide Area Augmentation System of the US, the European Geostationary Navigation Overlay Service and the multi- functional Satellite Augmentation System of Japan
