Positioning Technology Gps/a-gps/lbs/wifi positioning IntroductionSource: Site Finishing Author: 08lr.cn update: May 03, 2013 popularity: 9 this week: 19 this month: 34 total: 2,134 times
In life, we often see the so-called mobile phone positioning of the application, for the tracking technology can not be incredible, we will think: How to do this? With today's positioning technology, a certain degree of pr
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
Introduction: In our application to provide users with location services, often want to provide users with accurate point of location services, which requires the user to cooperate. We must first detect the user's mobile phone's GPS is currently open, if not open, pop-up dialog box prompt. If users do not cooperate with us, we can only use the base station positioning method. If our application must be opened by the user to use the

GPS is short for Global Positioning System.
Android provides a dedicated LocationManager and Location manager for the GPS function. All services and objects related to GPS positioning will be generated
1 How to fake GPS?GPS fake There's a strange phenomenon you need to put fake GPS code into a service without knowing if the system is the source of the fake information. The results of the experiment are required to be placed in the serviceThe code is roughly as followsPackage Com.yiqiding.ktvbox.view.service;import Java.lang.reflect.method;import Android.app.ser

Introduction to the GPS software of G1 and how to enable the GPS module
We still use G1 as an example. G1 is equipped with a hardware GPS chip. However, most of the available GPS maps in G1 currently do not support offline image libraries, that is to say, you must ensure that you have a cmnet or Wi-Fi connection
Analysis and Solution to common problems of porting GPS applications in LinuxOS: Linux 1. directly provide functions for third parties
Cause: the design of the main chip and the change of the GPS chip often make the GPS driver updated.

Recently, focused on the field of digital player Newman launched a based on GPS navigation-oriented MP4 player, model for E666, and the price of 1999 yuan to the market has brought absolute shock. Newman E666 equipped with 3.5-inch 260,000 color TFT touch screen, resolution up to 320x240, image clear, exquisite.
As a GPS navigator, Newman E666 has a global positioning and navigation function, satellite pos
