How India's first navigation satellite system will aid mobility

IRNS is an independent regional navigational satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as region extending up to 1500 from its boundary, which is its primary service area

The Extended Service Area lies between primary service areas and area enclosed by the rectangle from Latitude 30 deg South of 50 deg North , Longitude 30 deg East to 130 deg East.

IRNSS will provide two types of services, namely, Standard Positioning Service (SPS) which is provided to all the users and Restricted Service (RS) , which is an encrypted service provided only to the authorised users. The IRNSS System is expected to provide a position accuracy of better than 20 m in the primary service area.

IRNSS consists of a space segment and a ground segment. The IRNSS space segment consists of seven satellites, with three satellites in geostationary orbit and four satellites in inclined geosynchronous orbit. IRNSS ground segment is responsible for navigation parameter generation and transmission, satellite control, ranging and integrity monitoring and time keeping.

Applications of IRNSS:

• Terrestrial, Aerial and marine navigation
• Disaster management
• Vehicle tracking and fleet management
• Integration with mobile phones
• Precise timing
• Mapping and geodetic data capture
• Terrestrial navigation aid for hikers and travelers
• Visual and voice navigation for drivers
