A-GPS Update

December 1, 2009

A-GPS Update Assisted GPS (A-GPS) improves location determination by obtaining “assistance” data from a network over the wireless communication channel. The result? Higher position accuracy, quicker location fixes, and improved coverage of service in difficult locations, such as urban and in-building environments. Also, in some cases, position calculations may...
