    PSLV-XL WITH IRNSS-1D HAS BEEN MOVED TO THE LAUNCH PAD: ISRO

    The Indian rocket that would put into orbit the country's fourth navigation satellite on March 28 was moved to the launch pad on Monday morning, said a senior official.

    "The rocket - Polar Satellite Launch Vehicle-PSLV-XL - has been moved to the launch pad or the umbilical tower. The rocket will be fixed to the umbilical tower," M.Y.S. Prasad, director, Satish Dhawan Space Centre (SDSC), told IANS over phone from Sriharikota.

    India's only rocket port is located at Sriharikota in Andhra Pradesh around 80 km from here.

    According to Prasad after the rocket is connected to the umbilical tower system, checks would be carried out including full rocket and satellite checks. The Indian Space Research Organisation (ISRO) is hoping to launch the rocket on March 28 evening if everything goes smoothly.

    Originally ISRO had planned to launch the 1,425 kg Indian Regional Navigation Satellite System (IRNSS-1D) satellite on March 9.

    But on March 4, ISRO deferred the launch after it found that one of the telemetry transmitters in the IRNSS-1D was not working properly. India has so far launched three regional navigational satellites as part of a constellation of seven satellites to provide accurate position information service to users across the country and the region, extending up to an area of 1,500 km.

    Though the full system comprises nine satellites - seven in orbit and two on the ground as stand-by - the navigation services could be made operational with four satellites, ISRO officials had said. Each satellite costs around Rs.150 crore and the PSLV-XL version rocket costs around Rs.130 crore. The seven rockets would involve an outlay of around Rs.910 crore.

    The entire IRNSS constellation of seven satellites is planned to be completed this year itself.

    The first satellite IRNSS-1A was launched in July 2013, the second IRNSS-1B in April 2014 and the third on October 16, 2014.

    Once the regional navigation system is in place, India need not be dependent on other platforms. Meanwhile European space agency Arianespace is also getting ready to launch two Galileo satellites on March 27.

    The two satellites would be launched jointly by a Soyuz rocket blasting off from French Guyana.

    According to Arianespace, the Galileo programme is Europe's initiative for satellite navigation, providing a highly accurate global positioning system under civilian control - to consist of 30 satellites in total, along with European control centres and a worldwide network of sensor and uplink stations.

    ISRO eyes a global role in satellite navigation

    The Indian Space Research Organisation has unveiled plans to gradually make its regional satellite navigation system global — akin to powerful position- telling systems such as the U.S.’ GPS and the Russian GLONASS. ISRO Chairman A.S. Kiran Kumar said four of the seven Indian Regional Navigation Satellite System (IRNSS) satellites are in orbit and the last three spacecraft would be added in orbit by March 2016. The IRNSS would provide self-reliance in the strategically important area of position-related information, he said at a users’ conference on global navigation satellite systems on Thursday. The focus now was on completing the regional constellation and extending it to South Asian Association for Regional Cooperation countries. “After that we will look at taking it gradually over the entire globe, may be in less than a decade. It could be done by adding a set of regional satellites over adjoining countries. We are working towards this with other countries – [South] Korea and the Gulf nations, to name a few,” Mr. Kiran Kumar said. The signals from the regional system were already available 1,500 km beyond the borders. In April this year, ISRO and the Airports Authority of India also completed GAGAN, focussed on airlines, airports and the civil aviation sector but applicable to land and sea-based services. GAGAN enhances the GPS- derived details of location and time of objects or persons. Both IRNSS and GAGAN, he said, would drive an unlimited set of personal, public and industrial users, from transportation, railways, forestry, farming, agriculture and security. Around 200 navigation receiver sets built by industry and using ISRO design would be out soon.

    Do you know when they are going to roll it out for public usage? Or are there any tie-ups with local Indian firms for e-marketing?

    MAKE IRNSS INDIA'S PRIMARY NAVIGATION SYSTEM: SCIENTIFIC ADVISER TO THE DEFENCE MINISTER

    BANGALORE: The Indian Regional Navigation Satellite System (IRNSS) should be made India's primary navigation system, said a top scientist on Thursday.
    "Once the seven satellites (Of IRNSS) are in place by March 31, (2016), the most important thing becomes the user segment and the receiver development for various applications," said G. Satheesh Reddy, scientific adviser to the defence minister, at the Global Navigation Satellite System (GNSS) User Meet 2015 organized by Indian Space Research Organisation (ISRO) and Airports Authority of India.
    "We have to keep one thing in mind, we always have GPS and GLONASS which are available worldwide... we need to compete with them in commercialization," he added.
    Reddy said that every Indian cell phone buyer must ask for IRNSS in his phone and even if five percent phone buyers get it, it would give a great fillip to the indigenous navigation system.
    ISRO scientists said that IRNSS is a better navigation system than GPS with precision time and location data.
    Like GPS, IRNSS too can find extensive use in many applications like car navigation, aircraft, smartphones and others, said Reddy, urging Indian industry to widely incorporate IRNSS navigation system into their manufacturing.
    "The industry has to play a very important role in seeing that we are able to manufacture our own receivers here which are able to incorporate IRNSS receiver into their systems or whichever (instruments and machines) are coming from abroad or manufactured abroad and brought here (should have IRNSS)," he added.
    He highlighted that IRNSS simulator and receivers must be developed at a very very low cost to empower IRNSS to compete with the GPS market and enable mass adoption. Reddy also advised ISRO to manufacture its chipsets at the lowest possible cost for great commercial success of IRNSS and GAGAN.
    Lauding GAGAN and IRNSS, he said both Indian developed technological systems have innumerable uses in the defence sector.
    "In the times when we need the signal.. our signal which is available to us is what makes the difference," said Reddy.
    He said IRNSS signals, data and positioning are reasonably good and meet the necessary navigation requirement of the armed forces.

    ISRO’S DESI GPS SYSTEM IS HERE

    http://timesofindia.indiatimes.com/...i-GPS-system-is-here/articleshow/49264167.cms


    AHMEDABAD: It's time we move away from the American Global Positioning System (GPS) and make way for our own desi navigation system — the Indian Regional Navigation Satellite System or IRNSS on our mobile phones.

    Beginning Thursday, ISRO will hold a major meeting in Bangalore involving location and navigation device manufacturers, mobile phone manufacturers and global information system (GIS) technology developers presenting to them the advantages of using the IRNSS technology over the current GPS technology. During the two-day meet, ISRO will demonstrate how the seven IRNSS constellation satellites once operational by July next year, will be significantly more accurate than the American GPS system. The meeting will also be attended by senior scientists from Space Application Centre (SAC) Ahmedabad.

    Unlike American GPS, ISRO is recommending a small additional hardware in handheld devices that can receive S-Band signals from IRNSS satellites and inclusion of a code in the phone software to receive L-Band signals. "Both these L and S band signals received from seven satellite constellation of the IRNSS are being calculated by a special embedded software which reduces the errors caused by atmospheric disturbances significantly. This in turn gives a superior quality location accuracy than the American GPS system," says a senior ISRO official.

    IRNSS will provide two types of services, namely, Standard Positioning Service (SPS) for all users and Restricted Service (RS), for defense users.

    On Monday, while addressing mediapersons, SAC director Tapan Misra said, "In times of disaster or any other eventuality, we will always want our own navigation system that can serve our own people rather than depending on a foreign navigation system. The Bangalore meeting is significant as representatives from navigation device manufacturing companies will be attending. We are trying to convince them to shift to IRNSS," says Misra.

    India's fourth IRNSS 1D satellite launched in March this year was important because this completed the minimum number essential for a navigation system. It carried two payloads — one for navigation and other for 'ranging' purposes. The navigation payload transmits navigation service signals to users, while the ranging payload satellite has a C-band transponder which helps accurate determination of the range of the satellite. The first three satellites in the series were launched from Sriharikota in July 2013, April 2014 and October 2014.

    ISRO chief: GAGAN is superior to all available GPS

    GAGAN (GPS Aided Geo Augmented Navigation) developed jointly by the Indian Space Research Organisation (ISRO) and the Airport Authority of India (AAI) is more accurate than any other global positioning system currently available, the ISRO chief has said.

    “GAGAN is better than any GPS as it ensures that at any given point in time, the measurements are reliable,” AS Kiran Kumar, Chairman, ISRO, said on the sidelines GNSS users meet 2015.

    Reliability
    “Standard GPS measurements can at times be off the mark by a significant value, but GAGAN-enabled signals can be relied on all the time. That is why aircraft are using it,” Kiran Kumar said.

    Other space-based navigation systems are GPS of the US, Glonass of Russia, Galileo of Europe. GAGAN and the upcoming Indian Regional Navigation Satellite System (IRNSS) of India aim to enhance the capability of GPS to provide accurate information, specifically for aircraft navigation.

    Referring to the common usage of GAGAN on the ground, Kiran Kumar said, “Right now cell-phone users are using Gagan-enabled positioning system.”

    ISRO enabled speed post services of India Post to spot the nearest post office through the satellite system in Mysore recently.

    Constellation of satellites
    ISRO will shortly complete the constellation of seven satellites to efficiently operate GAGAN.

    “This has been our major focus. After completing it, we are looking at how we can roll out in Saarc countries and later take it global,” Kiran Kumar said.

    “Currently it is a thought process. It will become reality as we are working with a few of the countries and add more countries. At present it is 1,500 km beyond Indian borders, same way we can add regional things and make it global, that is one thing we are working upon. We are in talks right now with South Korea and the Gulf countries. We’ll expand slowly. Maybe in a decade, we can do it,” he added.

    “Only regional users can take advantage of IRNSS now. GAGAN is a part of global system already. Any aircraft with satellite-based receiver can make use of it.”

    ISRO Will Launch India’s Own Satellite Navigation: IRNSS; Will end American Monopoly Of GPS

    Did you know that the Global Positioning System used by almost all countries in the world is controlled by USA Govt?

    If they want, they can switch off this GPS without any explanation!

    During the Kargil war, Indian Army and Air force had to use America’s GPS, and it was a very scary situation.

    American monopoly on satellite based navigation is all set to end now, as Indian Space Research Organisation or ISRO will launch India’s own ‘desi’satellite based navigation next year. Christened as Indian Regional Navigation Satellite System or IRNSS, this navigation system would be controlled by Indian Govt.

    Last week, scientists at ISRO started a series of meetings with various location and navigation device manufacturers, mobile phone companies and global information system (GIS) technology developers from all over the world; to explain them the advantages and benefits of using IRNSS. In these meetings, senior scientists from Space Application Centre (SAC) Ahmedabad had also participated, to showcase how India’s very own IRNSS has technical advantages over American GPS system.

    As per reports coming in, ISRO will offer two types of services via IRNSS:Standard Positioning Service (SPS), which would be available for all users (mobile phones, ecommerce services, digital services) and Restricted Service (RS), which would be exclusively for defense users.

    Advantage: IRNSS
    India’s IRNSS will use seven constellation satellites, which would be operational from July, 2016. Besides providing a leading technological edge over GPS, IRNSS will enable handheld devices to receive seamless S-Band signals from these 7 satellites.

    Additionally, once a simple code is added in the mobile phones, they would be able to receive L-band signals as well.

    A senior ISRO official said, “Both these L and S band signals received from seven satellite constellation of the IRNSS are being calculated by a special embedded software which reduces the errors caused by atmospheric disturbances significantly. This in turn gives a superior quality location accuracy than the American GPS system,”

    Self Reliant India: The Dawn of Technological Age
    During various situations such as natural disasters, a military operation or simply business requirements, we had to be dependent of America’s GPS platform to help navigate our operations. This made us reliant on a foreign entity, and scares of data theft, data manipulation and spying were always present.

    With IRNSS, India will become part of that exclusive club to have their own satellite based navigation system.

    Although some other countries do have their own such satellite based navigation systems, but they are not that efficient and hence, unreliable compared to GPS system.

    China has their own BeiDou Navigation Satellite System, which is based on just two satellite constellations, compared to India’s 7. BeiDou is still under construction, and American GPS is the primary source for Chinese as of now.

    Galileo is a satellite based navigation system of Europeans, currently under development. The fully functional Galileo, which can act as an alternative to GPS can only be launched after 2020.

    As of now, the only viable and reliable alternative to GPS is Russia’s GLONASS(GLObal NAvigation Satellite System), which can be regarded as GPS equivalent. They have a full orbital constellation of 24 satellites, which is as powerful as America’s GPS.

    After GPS, and GLONASS, it would be India’s very own IRNSS which can be described as a formidable force to reckon with for satellite based navigation.

    This is one of those new technological masterstroke by India.

    As i understood Russia’s GLONASS was still under construction and not had enough money to support their program. there was also talks with ISRO to help and co operate to improve GLONASS, then how can it be equivalent to GPS

    No, GLONASS was already finished but now there is rumour that they may have fiscal problem to replace those satellites which are near the end of lives.

    And no, they are not asking ISRO to improve their system. They are talking with India government to allow them to set up the ground base station in India. These stations are the important part of any GPS system, which will dramatically improve the accuracy of signal. The same applies to American GPS.

    IRNSS is just for navigation for civilians and military.
    Spy satellites are different and have much higher resolution. Anyway, India has some spy SATs as well:-
    RISAT-1
    RISAT-2
    CCI Sat(not confirmed it was launched or not. It is said that it was almost to go in sky in 2014. Now, it's a secret. :devious:)
    CartoSat series of satellite.
    Yet Cartosats are communication for IAF, IA and IN, they are believed to carry spying capable observation instruments with them. Many countries blamed but they couldn't prove a $hit against us. :peace:
