why should we limit ourself to 7 satellites.we should aim for atleast 24 satellites to ensure global coverage.

do India needs its own GPS system?
- Lets discuss.
once we perfect GSLV III then we should start working on our own GPS system.

i think yes....
--ISRO to launch Indian Regional Navigational Satellite System (IRNSS) satellites in 2013--
Indian Space Research Organisation (ISRO) chairman, Dr K Radhakrishnan said yesterday that India would launch the first of the Indian Regional Navigational Satellite System (IRNSS) satellites in 2013.
A satellite navigation system comprises a system of satellites providing autonomous geo-spatial positioning with global coverage.
The system allows small electronic receivers to determine their location ( longitude, latitude and altitude) to within a few metres using time signals transmitted by radio from satellites.
Receivers calculate position and time with high degree of precision, for use in a variety of applications.
Speaking at the convocation ceremony of the National College in Bangalore, he said, ''In the next two years, India will have its very own navigation satellite.''
The system would be part of a seven satellite constellation developed at a cost of Rs 1,600 crore, providing Indian users accuracy levels of less than 20 metres throughout India and across an area stretching over 1,000 km from Indian borders. Capable of both military and civilian applications, an indigenous navigation system would see India gain entry to an exclusive club of nations having individual navigation systems.

Isro chairman K Radhakrishnan said that Isro is preparing to launch the first of the navigation satellites constellation in June to provide position accuracy better than 10 metres over India and the region extending up to 1,500km around the subcontinent.
BANGALORE: India will launch in June the first of the seven Indian Regional Navigation Satellite System (IRNSS) into the earth orbit to provide real-time position, navigation and time services to multiple users, the space agency chief said on Saturday.
"We are preparing to launch the first of the navigation satellites constellation in June to provide position accuracy better than 10 metres over India and the region extending up to 1,500km around the subcontinent," state-run Indian Space Research Organisation (Isro) chairman K Radhakrishnan told reporters on the margins of a space event here.
The IRNSS-1 will be launched on board the polar satellite launch vehicle (PSLV-C22) from the spaceport at Sriharikota off the Bay of Bengal on Andhra Pradesh coast, about 90km northeast of Chennai.
The space agency plans to launch the second navigation satellite three months after in-orbit tests of the first one and the remaining five satellites over a 14-month period by 2014-15.
The IRNSS will have a space segment (constellation of satellites and signal-in-space), a ground segment and a user segment to provide multiple services on 24x7 basis under all-weather conditions to a host of users, including airlines, ships and observational posts.
"Three satellites will be placed in the geostationary equatorial orbit (GEO) at 34, 83 and 131.5 degree east and two satellites each in the geosynchronous orbit (GSO) with equator crossing at 55 and 111.5 degree east at an inclination of 29 degree," Radhakrishnan said after inaugurating a two-day symposium on the 'Saga of Indian Remote Sensing Satellite Programme: 25 years since IRS-1A', being held here this weekend.
The navigation system will have two signals in L5 and S-band on 1176.45MHz frequency and 2492.028MHz frequency with provision for downlinks.
"The constellation system provides two basic services — standard positioning service for civilian users and restricted service for authorized users. The navigation software is being indigenously at the satellite centre in Bangalore," Radhakrishnan added.

How are they measuring 1500 km ? is 1500=r ? If so then too 2r will 3000 kms, while we need it at least 5000+ kms covered if we have to use it for military purposes 
wouldn't it be too small area? @sayareakd , @Yusuf
Or they are measuring it from the borders ? = File:IRNSS COVERAGE.png - Wikipedia, the free encyclopedia

I think the report says 1500km is additional to the landmass of India. Basically what it means is that it will cover to somewhere in Afghanistan. All of Pak will be covered. And it's but obvious. It will be required to deliver those GPS guided bombs and missiles.

The image shows an area 1600-2300 Km beyond the border of India as per Google Earth ruler.

Oh I misread the article, I missed "and" of the sentence "India and the region extending up to 1,500km around the subcontinent". Thanks for correcting me!
Yeah GLONASS will do the rest of the job.
Yup! it is more than the declared coverage of the IRNSS.The image shows an area 1600-2300 Km beyond the border of India as per Google Earth ruler.

India Gears up to Launch First Navigational Satellite | Science | www.indiatimes.com
India plans to launch its first navigational satellite in June, a top official of the Department of Space (DoS) said today.
The first Satellite of Indian Regional Navigation Satellite System (IRNSS) constellation, IRNSS-1 will be launched by PSLV-C22, said DoS Secretary and Chairman of Indian Space Research Organisation (ISRO) K Radhakrishnan. According to ISRO officials, IRNSS is an independent regional navigation satellite system, designed to provide position accuracy of better than 10 metres over India and the region extending about 1500 km around the country.
"It is designed to provide an accurate real time Position, Navigation and Time (PNT) services to users on a variety of platforms with 24x7 service availability under all weather conditions," an ISRO official said.
IRNSS provides two basic services -- standard positioning service for common civilian users and restricted service for special authorised users, the official said.
"We are planning for June launch," Radhakrishnan told reporters after addressing a symposium on 'Indian Remote Sensing Satellite (IRS) Series: A Saga of 25 years'.
IRNSS-1 would be tested in orbit for three-four months once it's launched, he said. ISRO has planned to have a constellation of seven satellites under IRNSS.
Speaking at the event, marking the 25th anniversary of the launch of India's first operational Remote Sensing Satellite IRS-1A, Radhakrishnan said India has planned 12 missions (both launch vehicles and satellites put together) in the next one year.
These include the Rs 450 crore Mars orbiter mission in October-November aimed at demonstrating India's technological capability to reach Martian orbit and paving the way for future scientific exploratory missions, and GSLV-Mk III experimental venture.
The GSLV-Mk III is conceived and designed to make ISRO fully self-reliant in launching heavier communication satellites of INSAT-4 class, which weigh 4500 kg to 5000 kg.
Radhakrishnan said India's remote sensing satellites are able to take images with a resolution of less than a metre (0.8 metres to be precise, according to an ISRO official). This means in those images, the official said, even ground features which are a little less than a metre wide can be recognised.
Radhakrishnan said ISRO proposed to launch remote sensing satellites with 0.6 metre resolution in two years and 0.25 metre in five years.
Former ISRO Chairmen U R Rao and K Kasturirangan spoke about the origin, growth and emergence of India as a world leader in the realm of satellite-based remote sensing in the past 25 years, at the two-day symposium, organised by Indian Society of Remote Sensing (ISRS) in partnership with other professional societies.
India today has 11 functioning remote sensing satellites, some of which are serving the country as well as the global community, according to ISRS.
India now has the largest constellation of remote sensing satellites in the civilian domain, dedicated to three main themes -- land & water, cartography, oceanography and environment, including meteorology and weather monitoring, it was noted.

Is there is a difference between IRNSS and GPS satellites in capabilities, payload, orbit, other than coverage?
