GPS is a global satellite navigation system maintained by the US that provides location and time information to users worldwide with an accuracy of 5 meters. NavIC is India's regional satellite navigation system developed by ISRO to focus on India and surrounding areas. It uses dual frequency bands to provide more accurate positioning of 20 meters for civilian use. NavIC aims to support navigation applications for mariners, vehicles and disaster management across India.

1. GPS Versus NavIC

2. Global Positioning System
 GPS (Global Positioning System) tracks the entire globe and
is maintained by the USA.
 GPS is a Space based Global navigation Satellite system that
provides location and time information.
 Freely accessible by anyone with a GPS receiver.
 The GPS had a position accuracy of 5 meters.
 GPS is easy to navigate as it tracks and tells the direction,
position ..etc to the User.

3. Navigation with Indian Constellation
(NavIC )
 Navic is the operational name of the Indian Regional
Navigation Satellite System (IRNSS) developed by ISRO.
 There are currently Seven IRNSS satellites in
geosynchronous and geostationary orbits.
 Navic has been designed to focus especially on India and
adjoining regions 1500 Kms (930 mi) around it, with plans
for further extension around India.

4. NavIC Services…
 NavIC will provide two types of Services
 Standard Positioning Service to all users
 Encrypted Restricted Service to authorized users(like
Military).
 NavIC will provide drivers and other users in India with
visual and voice navigation.
 Its primary beneficiaries will be Indian mariners and
fishermen, who are being provided with NavIC handsets.

5. NavIC System Supports…
 NavIC is designed for a position accuracy better than 20
meters in India.
 Navic uses a different frequency band and Integrating
NavIC also requires hardware changes on the chipset. So
NavIC Support cannot be extended to older phones.
 The first phone in India with NavIC support is Realme X50
Pro 5G

6. GPS versus NavIC
GPS NavIC
GPS or Global Positioning System
tracks the entire globe and is
maintained by the USA.
Navic is the operational name of the
Indian Regional Navigation Satellite
System (IRNSS) developed by ISRO,
INDIA.
First Satellite Launch : 1978 First Satellite Launch : 2013
GPS uses a single frequency band (L
band ).
NavIC satellites use dual frequency
bands :: L5 band (1176.45 MHz) and S
band (2492.028 MHz),
GPS makes calculations a bit more
complex due to single frequency band.
NavIC system is relatively more
accurate due to dual frequency bands .

7. GPS versus NavIC
GPS NavIC
Lifetime of each Satellite : 10 Years Lifetime of each Satellite : 12 Years
GPS requires 24 Satellites to be
operational and has around 31 satellites
in orbit.
NavIC currently consists of 8 Satellites.
Precision : 5 Meters Precision : 20 Meters for Civilian and
:10 Meters for Military

8. Applications of NavIC
 Terrestrial, Aerial and Marine navigation
 Disaster Management
 Geodetic Data Capture
 Precise Timing ad Mapping
 Vehicle Tracking and fleet Management.
