Global Positioning System (GPS) and Assisted Global Positioning System (AGPS) are both satellite-based positioning systems but the working principle of these two systems is different. GPS works on the principle of trilateration where distance is measured from three satellites to calculate the position of a receiver on Earth. However, AGPS makes use of a cellular network and thereby eliminates the need for additional hardware like receivers and antennas.
In this article, we will discuss the difference between GPS and AGPS in detail. We will also look into the benefits of AGPS over GPS. Stay tuned!
What is GPS?
GPS stands for Global Positioning System. GPS is a constellation of over 30 satellites that orbit the Earth. GPS allows users to determine their precise location on Earth. GPS is used by Navigation systems in vehicles, smartphones, and other devices. GPS can also be used for tracking purposes. GPS is funded by the United States government and is managed by the United States Air Force. GPS is free to use and is available to anyone with a GPS receiver. GPS was first developed in the 1970s for military use. GPS was made available for civilian use in the 1980s. GPS has transformed many aspects of our lives including transportation, navigation, and surveying.
What is AGPS?
AGPS is a satellite-based navigation system that uses a constellation of satellites to provide accurate positional information. AGPS stands for Advanced GPS and is an improvement over the traditional GPS system. AGPS provides more accurate positioning information by using a larger number of satellites and using more sophisticated algorithms. AGPS is particularly useful in urban areas where there are a lot of tall buildings that can block the signal from traditional GPS satellites. AGPS is also used in aircraft and ships, where it can provide more accurate positioning information than traditional GPS.
Difference between GPS and AGPS
GPS, or Global Positioning System, is a system of satellites that provide information on location and time. This system can be used for a variety of applications, including navigation, mapping, and tracking. AGPS, or Assisted GPS, is a technology that augments GPS signals with additional data from terrestrial sources. This can help to improve the accuracy of GPS readings, especially in difficult environments such as urban areas. While GPS is typically accurate within a few meters, AGPS can improve this to within a few centimeters. As a result, AGPS is often used in applications where high accuracy is critical, such as surveying and precision farming.
Conclusion
GPS and AGPS are both satellite navigation systems that use signals from satellites to calculate a location. The main difference between the two is that AGPS uses cell towers and Wi-Fi hotspots to help pinpoint a location, while GPS relies solely on satellites. This makes AGPS faster and more accurate in urban areas where there are many obstructions.
