V. Narayanasamy, the Minister of State in the Prime Minister’s Office, Ministry of Personnel, Public Grievances and Pensions, Bengaluru, inaugurated ISRO Navigation Centre (INC), established at Indian Deep Space Network (IDSN) complex at Byalalu, about 40 km from Bangalore on 28 May 2013.
The ISRO Navigation Centre (INC) is the important element of Indian Regional Navigation Satellite System (IRNSS), which is an independent navigation satellite system developed by India.
At the inauguration event, V. Narayanasamy also gave the awards instituted by Astronautical Society of India (ASI) and ISRO.
Role of ISRO Navigation Centre (INC)
• The ISRO Navigation Centre (INC) will remain the focal point of critical operations of IRNSS.
• The INC is responsible for providing the time reference, generation of navigation messages and monitoring and control of ground facilities which include ranging stations of IRNSS.
• INC will also host various technical facilities for supporting various navigation functions.
• The data from overall network of twenty one ranging stations of IRNSS will be sent to the data processing facility at INC where it will be processed to generate the navigation messages. The navigation messages in turn will be transmitted from INC to IRNSS satellites through the spacecraft control facility at Hassan.
• INC is also connected to ranging stations as well as the satellite control facilities through two highly reliable dedicated communication networks which consist of satellite and terrestrial links.
• The host of network of satellite communication links is INC.
About Indian Regional Navigation Satellite System (IRNSS)
• Indian Regional Navigation Satellite System (IRNSS) will have a total of seven satellites network and it will enable the users in determining the location as well as time accurately.
• All these satellites will be positioned in the geostationary and inclined geosynchronous orbits 36000 km above the surface of the Earth.
• The coverage of IRNSS will extend all over India and its neighbourhood.
• All the IRNSS satellites are equipped with high precision atomic clocks and continuously transmit navigation signals to users.
• IRNSS will have an overall network of twenty one ranging stations geographically distributed in India. These stations will facilitate data for orbit determination of IRNSS satellites and monitoring of the navigation signals.
