The first is higher prices. There are two GPS schemes adopted on the market. Most of them are hard GPS schemes, that is, the GPS solution contains RF and baseband (BB), such as: Sirf, Atmel, NEMERIX, Global Locate (acquired by Broadcom) and other manufacturers provided such a solution; the second is soft The GPS solution is to integrate the GPS baseband and the back -end main chip (multimedia application processor). You only need to add the GPS RF front end to form a GPS receiving solution, such as the GPS solution of Meixin. Compared to the hard GPS solution, the soft GPS solution undoubtedly has a relatively large advantage in price; however, the development cycle of the soft GPS solution is long and requires Host to have strong processing capabilities. At present, the cost of mainstream hard GPS solutions is more than $ 8, and the cheapest is about $ 6; the cost of soft GPS is basically about $ 2 to $ 3. Compared to the mobile phone solution of many overall BOMs in the market at $ 50 (or even lower), the GPS function can only be positioned in the mid -to -high -end market. Therefore, in order to enter the high and low -end market with huge shipments, a lower -cost GPS solution is required.

　　Second, the map business of GPS lags behind. Most friends who have used GPS navigation services have complained: the navigation maps used cannot be updated in time or even a lot of errors; the map software used is not bad in large cities, but when it is in small cities or counties, the map is accurate The degree is very low. Therefore, the improvement of map service levels will definitely promote the popularization of GPS applications.
