system.
Inertial Navigation SystemINS is an auxiliary navigation system that uses a accelerometer and gyroscope to measure the acceleration and rotation of an object and uses a computer to continuously estimate the position, attitude, and speed of a moving object. It does not need an external reference system and is often used on airplanes, submarines, missiles, and various spacecraft.
GPS (global positioning system) Global Satellite Positio
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.

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
Android GPS module is gps.default.so in the system/lib/hw/directory, general GPS-enabled mobile phones should implement this module and real GPS hardware interactionthe GPS in QEMU is to construct a gps.default.so, but this so does not deal with real hardware, just an analog interface, its code in in Sdk/emulator/
Thank you for your patience. This book is expected to be available in middle March. From today on, I will include some of the content of this book in my blog. Note that the original article is serialized without being edited by the publisher, so it may look a little non-professional.
In the appendix, Mr. Wu Jinliang, one of the authors and reviewers, discusses the positioning and learning methods of this book. I believe that these discussions can resonate with readers.

At present, we do the M-end will be used to locate, when the user first open the H5 page will start GPS positioning, and combined with Baidu map to find the city. According to our logical thinking is GPS positioning to obtain latitude and longitude, to the background call Baidu an interface to find the city name.

Milugps is a simple GPS software for your mobile phone. This software can run on wm5.. Net CF 2.0 platform, which can be connected to a GPS receiver (such as a Bluetooth GPS receiver) connected in the form of a serial port. maps can be converted from Ozi using map spaces.
This software has two main purposes: one is to learn. NET development under wm5; the othe
GPS/CPS tests are being conducted these two days, and there are always some problems with GPS. Last night, I suddenly thought that if the GPS interface is on the web, the car owner (his family or company) can query it through the Web. Different permissions give different detailed query results. Only the highest level is handled by the Administrator. This will mak
I have always imagined that drones can fly farther and more stably, and can be achieved through 4G signals. Now DJI has helped us achieve this. It is indeed a great company:Features:

When the yellow light was on, the master ran to the station and caught the bus in time.This is a great example of a good idea that makes life
