[CA] IRNSS - 1 Series Satellite
Apr 29, 2016
[CA] IRNSS
IRNSS
What is IRNSS?
·
Indian Regional Navigation Satellite System (IRNSS).
·
2006: Government approved project with ~Rs.1500
crores.
·
American Global positioning system has 24 orbiting
satellites, a global network of ground stations. Thus GPS covers every part of
the world.
·
But, given this small budget, it is beyond ISRO’s limit
to maintain 24 satellites to cover entire globe,
·
Therefore, our GPS will use just seven satellites,
and try to cover India + 1,500 km beyond its borders.
·
HQ: ISRO Navigation Centre at Byalalu, near
Bangalore. It’ll control this system.
7 Satellites of IRNSS
·
3 satellites - These three of the satellites will be
placed over the equator, in the geostationary orbit; they match the Earth’s
rotation and therefore appear from the ground to remain at a fixed position in
the sky.
·
+4 satellites - will be in pairs in two inclined
geosynchronous orbits; from the ground, these satellites will appear to travel
in figures of ‘8’ during the course of a day.
·
All seven IRNSS satellites will be at a height of
about 36,000 km, taking a whole day to circle the Earth.
·
In future, we can add more satellites to increase
coverage surrounding India and one day 25-30 satellites to cover entire earth,
just like American-GPS.
·
So far 6 out 7 satellites launched

Benefits of IRNSS
·
Will serve both civil and military users.
·
Will provide time-location coordinates on land, sea
and air.
·
Cell phone apps- for mapping, driving, hiking in
jungle and remote areas.
·
Forest department: Putting out wildfire, tracking
endangered animals.
·
Fleet Management e.g. taxi or truck company can
monitor whether their driver is on right path or not.
·
Disaster Management.
·
During war: naval fleet Management, missile
navigation etc.
·
IRNSS will offer two services: (1) Standard
Positioning Service: that will be accessible to anyone; (2) Restricted Service:
Will be available only to the military and other government-authorized users.
·
At present only three countries have their own
global navigation systems: (1) USA - GPS; (2) Russia - GLONASS and (3) China -
Beidou
