Difference Between GPS vs AGPS Definition, Works, Performance etc.
| Properties | GPS | A-GPS |
| Definition | GPS works on satellite based navigation system | AGPS works on advanced GPS with the help of mobile network and internet |
| how does it work | GPS receives signals from satellites and determines position from signals from at least four planets | A GPS provides fast position based on signals received from mobile towers and the Internet |
| Signal Source | only gives satellite signals | Uses satellite, mobile networks and the Internet |
| Time to receive signal | GPS may take some time to receive signal | AGPS takes less time as compared to GPS |
| Accuracy | GPS gives accuracy up to 5 to 10 meters | A-GPS gives accuracy less than 5 meters |
| Dependency | No need for internet or mobile network | A-GPS is dependent on mobile network and internet |
| Performance in urban areas | Tall buildings in cities or narrow streets, trees in forests can weaken the signal | A GPS provides good accuracy in narrow streets urban areas with |
| Performance in rural areas | works well in rural areas | AGPS may be limited due to lack of mobile net |
| initial cost | GPS includes the cost of the receiver but no additional data costs | A GPS may include the cost of the receiver and additional costs for data transmission |
| Data consumption | There is no need of internet in GPS because GPS receives signals from satellites | Internet data is required for data transmission in A-GPS but with the help of data, A-GPS works better than GPS because A-GPS is a subgrade version of GPS |
| Power Consumption | Receiving satellite signals consumes a lot of energy. | Downloading data from GPS requires the help of internet, which consumes a lot of energy.. |
| Benefits | No need of mobile network, good performance in rural and remote areas, | faster signal reception, better accuracy in urban areas, AGPS works well |
| Limitations | It may take longer to get a signal Signal may be weak in urban areas Signal may be weak in narrow streets Tall buildings and tall trees may weaken the signal | A GPS depends on mobile network and internet Accuracy may decrease if there is a lack of network |
