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.

This information is included in the NMEA output by the GPS receiver. The eighth field stored in gprs mc.$ Gprs mc, 015834, A, 374

Original site: http://www.cnblogs.com/magicboy110/archive/2010/12/09/1901669.htmlThere are many professional materials about GPS theory on the network, and this paper tries to introduce the basic principle of GPS positioning in a way that programmers can easily understand, hoping to enlighten the friends who do GPS development. Of course, this article does not i

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

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

ObjectiveLand transportation is the largest application field of GPS satellite positioning system, since the implementation of the satellite positioning system in 08, our province has played a prominent role in vehicle monitoring and dispatching: the main functions include vehicle tracking, route planning and navigation, information inquiry, Traffic command, emergency assistance, etc. It can be said that the satellite positioning system has become the

This is a creation in Article, where the information may have evolved or changed. Recently Pokemon Go Fire not, the result people server can't carry, only accept GPS location information in Australia client landing request. Today I have a small demo, on the jailbreak of the iphone on the system's GPS positioning information to change. Steps: On the Xcode8-beta new Blank Project Edit scheme Default Location

From: http://www.linuxidc.com/Linux/2011-09/42454.htm Concepts and basic classes Recently I learned GPS, so I made a GPS signal parsing tool on the Android system (HTC G7 mobile phone). The following is a summary. Thank you for your correction. Function: 1. obtained the location GPS information, including longitude and latitude, speed, and direction. 2. Satelli

The GPS system consists of three parts: the spatial part-GPS satellite constellation; Ground control part-ground monitoring system; User device part-GPS signal receiver. GPS satellite constellationThe GPS working satellite and its constellation are composed of 21 working

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

Only systems above mobile5.0 and wince6.0 are supported. You can add components when customizing the system. Gpsid is a middleware, which is equivalent to a virtual serial port dedicated to GPS data. It supports simultaneous opening and operation of multiple applications. But what I'm worried about is that this gpsid is fixed by Microsoft and all the data is rigid. What if I want to get some raw data? Can raw data be obtained? Some special

Basic tutorial on Android-10.14 Android GPS1. Locate related APIs 1) LocationManager Official API documentation: LocationManagerThis is a system service and cannot be new directly. You need: LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); In addition, do not forget to add permissions for GPS positioning: Okay. After obtaining the LocationManager object, we can call the following common methods: AddGpsStatusList

Today, because of the needs of the work, the previous compilation of a GPS test program has been revised again. This program is a bit of a history, I wrote 11 years, when I learned how to develop Android, is an experimental work. Now the work needs to be put back out to fix. At the same time I found that the Android GPS service is not deep, so today I deliberately read some information about

Today, due to work needs, I took out a previously written GPS test program and modified it again. I wrote this program for 11 years. It was not long before I learned Android development. It was an experimental work. Work now needs to be done again. At the same time, I found that I do not know much about the GPS service of Android, so today I read some information about the

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

Details Nokia introduced a new Bluetooth GPS receiver LD-3W during its 3gsm 2006 period. As an upgraded version of the LD-1W, Nokia claims LD-3W positioning accuracy up to 5 meters, support path planning and voice navigation, can be used with a variety of navigation software, and compatible with Nokia s60 platform mobile phone. This LD-3W and last year launched the LD-1W appearance, size, weight are completely consistent, the difference is that the

GPS intermediate driver Since the introduction of GPS intermediate driver (gpsid) in Windows Mobile 5.0, it has developed a global positioning system (GPS) windows Mobile applications become much simpler. The reason is that it adds an intermediate layer between the application program compiled by the developer and the GPS
