Problems solved by technology

The cost of mobile terminals with built-in GPS receivers is very high, so the popularity is not high
If the user of the existing mobile terminal that does not support the AGPS positioning function wants to use the AGPS function, he must purchase a mobile terminal that can support the AGPS positioning function, which greatly increases the cost for the user to use the AGPS function

Abstract

The invention discloses a mobile device containing AGPS orientation function that includes a mobile terminal used to send AGPS data request information to assistant orientating entity through wireless network and receive the AGPS data; and a GPS receiver locating outside the mobile terminal that is used to receive AGPS data from the mobile terminal and capture target GPS satellite based on the AGPS data to gain GPS data. The invention also discloses an assistant global orientation method.

Description

technical field [0001] The present invention relates generally to assisted global positioning systems and methods. More specifically, the present invention relates to a mobile device with AGPS positioning function and an assisted global positioning method. Background technique [0002] As is well known, a position determining technology using a Global Position System (Global Position System: GPS) has been widely used in various fields, such as mobile terminal positioning, vehicle positioning, and the like. In order to determine the current location of a mobile terminal using GPS, a GPS receiver needs to be installed in the mobile terminal. The GPS receiver can continuously receive GPS data from GPS satellites, and calculate the current position of the mobile terminal according to the received GPS data. GPS data usually includes navigation message, pseudo-range information and so on. There are following defects in this method of directly utilizing the GPS receiver to deter...
