A-GPS

Offering a detailed look at all the technical aspects and underpinnings of A-GPS, this unique book places emphasis on practical implementation. It reveals how A-GPS enables the computing of a position from navigation satellites in the absence of precise time--a topic not covered in any other book.

Frank van Diggelen is the technical director of GPS systems and the chief navigation officer at Broadcom Corporation. Dr. van Diggelen is also a technical advisor of assisted GPS for NavtechGPS. He holds a Ph.D. in electrical engineering from Cambridge University, England.
