Indian Navigation Constellation (NAVIC) aka IRNSS

[jalsa]

I think IRNSS will be quite useless for civilian applications.

US GPS Satellites Orbit at 21000 KMs and Signal strength we receive in a smartphone is around -150 to -160 dBm and when the sky is clear we get around 3 meter max accuracy in your smartphone. In case of IRNSS the satellite is at 36000 KMs and an a result the Signal we receive is much weaker, I am guessing it to be far worse than -160 dBm and when it is cloudy it will be almost unusable. You will get 10 meter accuracy max with clear sky and that pales in comparison with 3-5 meter accuracy you get with GPS/GLONASS with today's High-end phones.

The real use of our own navigation system will be for the Military with Encrypted Signals.

Countdown started. All the best ISRO !!!

Countdown for IRNSS 1-B commences

The launch of the satellite is scheduled at 5.14 PM on April 4 from Sriharikota spaceport

The 58-and-a-half hour countdown for the launch of country's second satellite for Indian Regional Navigation Satellite System IRNSS 1-B today commenced and was proceeding smoothly at the Satish Dhawan Space Centre at Sriharikota, some 100 km from here.

"The countdown for the launch of IRNSS 1B commenced at 6.44 AM and it is continuing smoothly," ISRO sources said.

The launch of the satellite is scheduled at 5.14 PM on April 4 from Sriharikota spaceport.

The April 4 launch is the second of the seven satellites planned for Indian Regional Navigational Satellite System (IRNSS), whose applications include terrestrial and marine navigation, disaster management, vehicle tracking and fleet management.

IRNSS, being developed by India is designed to provide accurate position information service to users in the country as well as the region extending up to 1,500 km from its boundary, which is its primary service area.

The system is expected to provide a position accuracy of better than 20 metre in the primary service area.

IRNSS is similar to US' Global Positioning System (GPS), Russia's Glonass and Europe's Galileo. China and Japan too have similar systems named Beidou and Japanese Quasi Zenith Satellite System respectively, ISRO officials said.

ISRO had launched IRNSS 1-A, the first in the series, on July 1 last year onboard its workhorse Polar Satellite Launch Vehicle (PSLV) C-22.

ISRO officials further said that two more satellites for IRNSS would be launched before the end of this year and with four satellite in their positions, the IRNSS could start functioning. The remaining three would alone increase the system's efficiency.

Yawn....PSLV successful launch is no big news. Soon GSLV will be the same.

it has become habit, hope it will continue like this for ever.

it has become habit, hope it will continue like this for ever.

Precisely and we need many more types of lauchers. Not just PSLV, GSLV and GSLV 3

Are the IRNSS only objective and design for GPS related functions. Is there room on the satellite for any other function.

ISRO Releases IRNSS Interface Control Document to Jumpstart Commercial Applications - Via Satellite

[Via Satellite 09-19-2014] The Indian Space Research Organization (ISRO) has released the Signal-in-Space Interface Control Document (ICD) for Standard Positioning Service (SPS) for the Indian Regional Navigation Satellite System (IRNSS). Currently under development, the IRNSS constellation will serve as India's domestic Global Navigation Satellite System (GNSS). The first two of seven satellites, IRNSS 1A and IRNSS 1B were launched in 2013 and 2014 respectively.

The Signal-in-Space ICD for SPS provides information for research and development purposes to facilitate commercial applications for the satellites.

IRNSS is designed to provide a Standard Positioning Service (SPS) and a Restricted Service (RS). Once completed, it is expected to provide position data with accuracy of better than 20 meters in India — the primary service area. The constellation will also cover 1,500 km outside the country for extended regional coverage.
