Difference Between GAGAN and GPS
GPS is a navigation system that is based on satellite and users can use it to reach their destination as they will be able to know the location and route of the place where they have to go. GAGAN is developed by ISRO which helps to make the GPS signals accurate. In this article, we will discuss the difference between GAGAN and GPS.
What is GPS?
The full form of GPS is Global Positioning System. This is a system in which a network of satellites is used in space to know the location of a certain place all over the world. It uses at least four satellites so that the location of a place can be determined. Different types of industries like travel, military, surveying, etc. use GPS to locate certain places where they have to reach.
What is GAGAN?
The full form of GAGAN is GPS Aided Geo Augmented Navigation. GAGAN was developed by the Indian Space Research Organization (ISRO). This is a system which is used to make the GPS signals reliable in the Indian subcontinent. It also covers areas from Africa to Australia. GAGAN is used to provide GPS signals in the hilly and mountainous regions so that remote areas can be easily located.
Difference between GAGAN and GPS
The table below shows the difference between GAGAN and GPS.
| GPS | GAGAN |
|---|---|
| US is the developer of GPS. | India is the developer of GAGAN. |
| The cost of GPS is high in comparison to GAGAN. | The cost of GAGAN is low in comparison to GPS. |
| The accuracy of the GPS is 5 meters | The accuracy of GAGAN is 3 meters. |
| GPS has the ability to locate any place all over the globe. | GAGAN has the ability to cover the Indian subcontinent. It also covers the areas from Africa to Australia |
| The frequency bands that GPS uses are L1 and L2 | The frequency bands used by GAGAN are L1 and L5. |
| The number of satellites that GPS uses is 24 Medium Orbit Satellites. | GAGAN uses three Geo Stationary Satellites. |
| GPS is used in navigation, surveying, and tracking. | GAGAN is used in sectors like aviation, maritime, and land-based sectors. |
Which is better: GAGAN or GPS?
GPS and GAGAN are satellite-based navigation systems. GPS covers the whole world and is developed by the US. Users can find any location all over the world through GPS. GAGAN was developed by ISRO in India and is used to locate places all over the Indian subcontinent. GPS is costlier than GAGAN but it has the ability to locate any place in the world.
Conclusion
GPS and GAGAN are satellite-based navigation systems which are used to track the location of certain places. GPS can be expanded as Global Positioning System and GAGAN can be expanded to GPS Aided Geo Augmented Navigation. GPS can locate any place in the world while GAGAN can locate places in the Indian subcontinent. It is also available to locate places from Africa to Australia.
