2. IRNSS
 IRNSS is an independent Navigation Satellite
System providing services in the Indian Region.
 IRNSS is being implemented by the
Indian Space Researched Organisation.
 The project is being managed by
the lead centre viz.., ISRO Satellite Centre.

3. IRNSS Applications
 IRNSS provides fairly good accuracy and
the whole constellation is seen all the time.
 There are plans to send integrity and
ionospheric correction messages to the user.
 In view of the independent nature constellation
it is planned to cater to specialized users.

6. Space Segment
 Space Segment consists of Seven satellites.
 3 satellites in GEO-Stationary orbit.
 4 Satellites in GEO Synchronous orbit.
 IRNSS Satellites are to be launched
by the Indian launcher PSLV.

8. Ground segment
 IRNSS Ranging & Integrity Monitoring stations (IRIM)
• Receive the data from the GEOs
and GSOs.
• Transmit the data to Navigation Control
Centre.
• Facilitate One way ranging of the
GEOs & GSOs.

9. Ground Segment(cont’d)
 IRNSS Navigation Control Centre(INC)
• Estimate and predict Ephemeris
• Determine Ionospheric corrections
• Determine Integrity
 Spacecraft Control Centre (SCC)
• Manage and maintain the Satellite Constellation

10. USER Segment
 The user segment consists of a specially
designed dual frequency receiver.
 All the seven IRNSS satellites will be
continuously tracked by user receiver.
 The user receiver will have min. G/T
of Db/K similar to GPS user receiver.

11. IRNSS Schedule
 The first Satellite will be launched
by mind 2009.
 The next three satellites will be
launched by end of 2010.
 The entire constellation will be
in place by 2011.
