In the current GPS market, there are various products, such as independent GPS receivers, soft GPS receivers (SoftGPS), and an GPS receiver (Host Based GPS) based on application processors. Both SoftGPS and Host Based GPS need to run a part of the program on the system's application CPU. Users need to integrate the program in the application system. The difficulty of integration is relatively difficult. The stability and scalability of the system will be affected. In terms of sexual limitation, the performance of GPS will also be discounted. The cost of independent GPS receiver provided by U-Blox has continued to decline, and has the advantages of easy integration. The performance is also better and stable and reliable. The mainstream technology of the market.

　　A-GPS makes instantaneous positioning possible, and U-Blox will provide users with convenient solutions for mobile phone design manufacturers to integrate. At present, all GPS receivers in U-Blox have the A-GPS function. U-Blox offers two A-GPS solutions: Assistnow Online and Assistnow Office. Assistnow Online is the end-to-end A-GPS solution of the U-Blox. When the GPS is started, it can download the information such as the star calendar, calendar, accurate time and other information through access to the server to shorten the first positioning time. Assistnow Offline is different from Assistnow Online. It does not need to establish a connection with the server when starting. Users can download the data files with different calendar provided by the size provided by the U-BLOX when it is convenient. When this data, you can calculate the required star data data and quickly start the positioning.

　　U-Blox 5 has optimized power consumption in terms of hardware and software, and the power consumption is as low as 50MW. The design goal of the U-Blox 5 is to focus on the strict requirements of performance and power consumption of the handheld equipment that focuses on battery-driven. U-BLOX 5 not only optimizes the power consumption during normal work, but also optimizes the power consumption during the capture phase. The power consumption of some other receivers in the market during the capture stage is 2 to 3 times larger than the normal work. Our receiving machine internal power management module can reduce power consumption when the CPU does not require full load, and users can perform more low power consumption modes. When appropriate, the receiver is set to a dormant mode. When sleeping The current is only 8μA.
