The odd solution to the intersection of two polygon in the GPS fence and the odd solution to the gps fencePreface The area of the origin area measured by the GPS measuring instrument is then submitted to the system. The system needs to check whether the origin area overlaps with other regions. If the overlap exceeds 10%, it is necessary to warn that the origin ar

GPS is converted into a hundred degrees longitude and latitude, and gps is converted into Baidu longitude and latitude Recently, Baidu's api is used for map positioning. Baidu's background sometimes stops to obtain the longitude and latitude, and the results are written by Apple. CLLocationManager is used to obtain the longitude and latitude in the backend. However, the latitude and longitude errors obtai

Apollo1.0 automatic driving on closed site If you want to complete the Apollo 1.0 "closed site tracking Automatic driving" function, we need to solve an important problem: I (unmanned vehicle) where. "Where I am" is completely dependent on the GPS (Global Positioning System) and IMU (ine

Global Positioning System (GPS) is a new generation of space satellite navigation and positioning system developed by the United States armed forces in the 70 's. Its main purpose is to provide real-time, all-weather and global navigation services for the three major areas of land, sea and air, and for some military purposes, such as intelligence collection, nuclear explosion monitoring and emergency communications, and is an important component of th

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

Abstract: In the WiTadowsCE embedded system, the serial port is used to implement GPS and PDA communication. First, introduce the data format of the GPS signal, and describe the system's hardware and software environment and serial communication. Finally, the GPS signal processing module is designed to describe in detail how to use the embedded programming langua

Sorry, the idea is good, but it is not possible to get a GPS global positioning on a Java phone. Now with GPS mobile phone is not much, this mobile phone needs GPS module, are smartphones and are high price mobile phones in the majority of such as Asus P526 Tatsu E616 A701, Wanda P800 Nokia 6110 Navigator and the newly listed domestic mobile phone Xiamen new N6 a

This paper expounds the method of using serial port to realize GPS and PDA communication in WITADOWSCE embedded system. Firstly, the data format of GPS signal is introduced, and the software and hardware environment of the system and serial communication are described. Finally, the design of GPS signal processing module, detailed description of how to use embedd

Real-time kinematic real-time dynamic difference method. This is a new and commonly used GPS measurement method. Previous static, fast static, and dynamic measurements all need to be calculated afterwards to achieve centimeter-level accuracy, the GPS-based GPS is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field.

The Global Positioning System (positioning System,gps) is a medium-range circular orbiting satellite navigation system that provides accurate positioning, speed measurement and high precision time standards for the vast majority of the Earth's surface (98%). GPS is widely used in military, logistics, geography, mobile phones, digital cameras, aviation and other fields, has a very powerful function. Android

This article describes the PHP calculation of Baidu map Two GPS coordinates of the distance between the method. Share to everyone for your reference. The implementation methods are as follows: Copy Code code as follows: /** * Calculate the distance between two coordinates (m) * @param float $fP 1Lat starting point (latitude) * @param float $fP 1Lon starting point (longitude) * @param float $fP 2Lat end point (latitude) * @param floa

First you need to know the GPS coordinate system. The GPS coordinate system follows the WGS-84 standard, under which the GPS chip can emit different packet formats. The GPS data can be classified into Gpgga, Gpgsa, GPGSV, GPRMC and so on, according to the different frame-frame head of the data. These frame headers iden
