AGPS - Assisted GPS

Ok.. I always mistaken that A-GPS (Assisted Global Positioning System) is based on triangulation of mobile GSM cell tower. Now then I realized that I am wrong.


AGPS is not so fanciful at all. 

Usually, network operator deploy a assisted server that download orbital  information of GPS satellites periodically. Then, AGPS makes use of mobile phone data connection to connect to assisted server to obtain pre-downloaded GPS information.
