Probably in the mobile communication of the professional vocabulary is the most familiar with the IMEI, whether in the purchase of a new machine or in the 2-hand market "Gold Rush" when the first action is to check whether the IMEI and fuselage on the motherboard of the IMEI is consistent as the main means to identify authenticity. This article on the IMEI of some of the ins and outs and recognition techniques to do a little bit of a brief introduction hope can help you a little.

Introduction to u-blox A-GPS Solutions
GPS applications are becoming increasingly popular. Vehicle Navigation and PDA/PND portable navigation devices are widely used in the market. In addition to combining photos, audio and video playback, it also gradually enters pedestrian walking navigation from Vehicle Navigation, with more emphasis on Location-basedService,LBS), that is, the positioning function extends value-ad
GPS (global positioning system), Global Positioning System:GPS consists of three parts:1. Space:The spatial part of GPS is composed of 24 working satellites. It is located over 20 200km of the earth's surface, evenly distributed on 6 orbital planes (4 in each orbital plane), and the orbital angle is 55 °. In addition, three active backup satellites are running in orbit. The distribution of satellites allows more than four satellites to be observed anywhere and at any time in the world, and the n

Model Design reason:
GPS provides global, around-the-clock, and real-time navigation Advantages. However, when satellite signals such as high-rise buildings, Boulevard, overpasses, and culvert tunnels are "blind spots, GPS cannot provide users with precise navigation information, especially continuous navigation information. Dr (dead-reckoning) uses a direction sensor (Gyroscope) and a speed sensor (mileage meter) to estimate the instantaneous locatio
