2. IRNSS is an independent regional
navigation satellite system
developed by India with an
operational name of NAVIC ("sailor"
or "navigator" in Sanskrit, Hindi and
many other Indian languages), which
also stands for ”NAVigation
with Indian Constellation”.
3. Reduce dependency on foreign owned
navigational systems like GPS (owned by US
Govt) or GLONASS (owned by Russia) during
times of conflicts esp. wars.
7. IRNSS Space Craft Control Centre (SCC)
IRNSS Navigation Centre (INC)
FUNCTIONS:
Estimating & Predicting IRNSS Satellite positions.
Calculation of integrity
Ionospheric & Clock corrections
Running the navigation software
8. IRNSS receivers.
DUAL-FREQUENCY:- L5 band: (1164 – 1189) MHz
central freq: 1176.45 MHz
S band: (2483.5 - 2500) MHz
central freq: 2492.028 MHz
SINGLE-FREQUENCY:- either L5 band or S band
These receivers are currently being manufactured and
Will be available soon.
9. Standard Positioning Service (SPS):
will be accessible to civilians.
will have an accuracy of upto 20m.
Restricted Service (RS):
will be strongly encripted and available only
to the military and other government
authorized users.
Both services will be carried on L5 & S band.
10. Cell phone apps- for mapping, driving, hiking in
jungle and in remote areas
Forest department- putting out wildfires, tracking
endangered species
During WAR- naval fleet management, missile
navigation etc.
Fleet management e.g. Taxi or truck companies can
monitor their vehicles.
Disaster management
11. GPS IRNSS

12. CONCLUSION &
FUTURE PROSPECTS
With IRNSS India has placed itself in the prestigious
league of countries having their own Satellite navigation
system and has proved the mettle of its advanced
technology.
In future, more satellites can be added to increase
coverage so much so that covering the entire globe- just
like GPS.
