GPS coordinates to Cartesian coordinates, gps coordinates CartesianAbstract We know that GPS coordinates are composed of longitude, latitude, and altitude. The precision and latitude are both angles, and the poster is the height. KDTree is often used for geographic-based search. When constructing a KDTree, GPS coordina

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

0 IntroductionThe maturation and development of GPS technology provide a powerful guarantee for the precise and real-time positioning of all kinds of moving vectors. such as the use of GPs to the vehicle or ship navigation and monitoring [2]. At the same time, with the development of information technology, the size of PDA becomes more and more compact, and the function of integration becomes more and more

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

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

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

The reason is that it adds an intermediate layer between the application program c

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.

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

The safety of GPS is not a new topic. The most famous example would be the 2011-Year-old Iranian hijacking of American drones [1]. December 4, 2011, the United States, a RQ-170 unmanned aircraft, flying in Iranian airspace. Instead of shooting it down, the Iranian military used some sort of GPs deception to make the plane land in Kashmar, north-eastern Iran. The intact drone provides the Iranian military w
