AGPS, Assisted Global Positioning System, refers to the operation mode of GPS. A-GPS also has a secondary server in the system. In A-GPS network, due to the influence of the receiver's working power and geographical location, the receiver can not obtain ideal positioning effect. The receiver often communicates with the auxiliary server with high power and accesses the network. Although it is related to the coverage of the cellular system, due to the task sharing between the A-GPS receiver and the secondary server, A-GPS is often faster and more efficient than the ordinary GPS system.

　　Economical GPS module series, specially designed for low power consumption and low cost. The advanced RF architecture and interference suppression ensure that the best performance can be achieved even in the adverse environment of GPS signals. Mass market terminal products with strict requirements on size and cost are the best choice.

　　It is a complete GPS module, which has the advantages of super anti-interference capability, fast positioning in weak signal environment, high sensitivity, miniaturization, etc. The high sensitivity, small static drift, low power consumption and lightweight volume of the GPS module are very suitable for the application of vehicle mounted and handheld devices such as PDA, vehicle monitoring, mobile phones, cameras and other mobile positioning systems, and it is the best choice for the application of GPS products.
