India to launch first navigational satellite on June 12

[Skull and Bones]

BANGALORE: India proposes to launch its first navigational satellite, which will provide terrestrial, aerial and marine navigation services and help in disaster and fleet management, on June 12.

The Indian Regional Navigation Satellite System-1A is slated to be launched on board home-grown rocket, PSLV-C22 XL at 1.01 am from Sriharikota spaceport on June 12.

The launch window will be open from June 10 to June 15, sources in the Indian Space Research Organisation here told PTI.

The 1425 kg IRNSS-1, which will have a life span of about ten years, will provide satellite-based terrestrial, aerial and marine navigation services, and also help in disaster and fleet management and vehicle tracking, an ISRO official said.

Bangalore-headquartered ISRO has planned to have a constellation of seven satellites under IRNSS by 2014-15.

IRNSS is an independent regional navigation satellite system, and once all the spacecraft become operational, it would provide position accuracy, similar to Global Positioning System (GPS), of better than 10 metres over India and the region extending about 1,500 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", the official said.

IRNSS provides two basic services -- standard positioning service for common civilian users and restricted service for special authorised users, the official said.

Best of luck to ISRO

 

[kurup]

Best of luck to ISRO .

Any idea when the GSLV is being launched ??

 

[soumya1989]

Best of luck.

 

[Rajaraja Chola]

Looking forward to it

Accuracy wrt US, Russian and Chinese navigational systems?

 

[ExtraOdinary]

ISRO! Making India proud since '69

Accuracy wrt US, Russian and Chinese navigational systems?

It may not be as good as them at the beginning.But first we need whole constellation of satellites to be fully operational.Once its fully operational we can ask smart phone companies operating in India to add support for IRNSS in their devices.It will be relatively cheap compared to western ones so Indian companies currently buying GPS and GLONASS services will get some cost benefits.It will be a win be a win scenario.Of course, the primary use for IRNSS system will still be military and strategic.

Large constellation means for covering large area, but CEP < 6m fairly expected, whether in a small area though

Accuracy wrt US, Russian and Chinese navigational systems?

GLONASS - 4.46&#8212;7.38 m depending on NSV (7-8)

GPS -2.00&#8212;8.76 m depending on NSV (6-11)

GLONASS + GPS - 2.37&#8212;4.65 m depending on NSV (14-19)

GLONASS' accuracy is expected to improve upto 0.6 m or better by 2020.

NSV is navigation space vehicle or you can say sats communicating with receiver.

Above datas are for military grade signals which are encrypted.Civilian signals has lower accuracy.

FOR Civilian Use

GPS - 5-20m

GLONASS-50-70m

best of luck...

 

[GR!FF!N]

thats a significant area I must say for a constallation with so few satellites.best of luck DRDO..

 

[selvan33]

Best of luck DRDO.

There is no use of IRNSS without covering large area at least the Indian Ocean region which is our Navy's operating zone.
