In the last share, I made an introduction to the technical framework of Baidu Apollo plan, as shown in the picture. 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
First of all, the acquisition of GPS data positioning methods are: GPS satellite positioning, WiFi location, base station positioning, AGPS positioning. The application of GPs is regarded as the core in the software of lbs industry. Several positioning ways to explain

Implementation ideas:
1. Use GPS to collect the signals from the satellites in the sky, and then transmit the data to the PDA through Bluetooth (of course other methods can also be used.
2. Run gpsgate on the PDA, accept data from GPS, and forward the data to the Internet through UDP sender to your home computer.
3. The data forwarded by gpsgate is connected to
Introduction to GPS
GPS is short for the English Global Positioning System (GPS. GPS was jointly developed by the US Army of land, sea, and air in 1970s.
A new generation of spatial satellite navigation and positioning systems. Its main purpose is to provide real-time, around-the-clock, and global navigation services f
Satellite positioning System-gps/glonass/Beidou:About GPS, GLONASS, Beidou, Galileo system of popular Science please Google itself.GPS is the most widely used global positioning network and is standard for almost all smartphones. In a few years, Russia's GLONASS positioning function also gradually joined the smart phone chip, and GPs to form a dual positioning sy
Android gets the current location through gps
GPS Positioning includes GPS Positioning and base station positioning: GPS positioning is based on satellite positioning, requires the head to be empty, the positioning error is 2-10 meters, the Base Station Network Positioning is based on the distance from the mobile phone
Simple Analysis of android Qemu GPS module
The gps module of Android is gps. default. so on the system/lib/hw/directory. Generally, the mobile phone that provides the gps function should implement the interaction between this module and the real gps hardware.
In Qemu,
0x00 PrefaceGNSS is an abbreviation for the Global Navigation satellite system. Chinese is called: Global satellite navigation system, global navigation satellite system.GNSS refers to all satellite navigation systems, including global, regional and enhanced, such as the U.S. GPS, Russian GLONASS, European Galileo, China's Beidou satellite navigation system, and related enhancement systems, such as the United States of WAAS (wide area enhancement syst
From the system and macro perspectives, after the application layer is stripped off, the work completed by the GPS receiver can be divided into three parts: signal measurement, data receiving, and geometric calculus.
Receiving data refers to receiving data transmitted in the form of bitstream or packets (excluding the data that can be obtained only by measuring the phase, frequency, and intensity of the signal ). Each satellite continuously sends it
A few days ago, a friend asked me to write him a GPS program, to learn latitude coordinates, and convert it into a Gaussian rectangular coordinate. It took some time to make a small program for him.
Later summed up, think of, many online friends will ask about the development of GPs some things. I will explain my procedure here first, then summarize the relevant experience and personal opinion.
At present
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
I have developed GPS-related embedded software for several years, So when talking about a program to test the GPS positioning module, the first reaction is to read the data from the GPS module through the serial port, and then parse the NMEA format data of GPS.
Today, due to work needs, I took out a previously written
Recently, a customer asked for a GPS Vehicle Monitoring System to display the location of a car on an electronic map in real time. He had never been in touch with it before and learned from the beginning.
First, you must understand the GPS signal format and transmission method. Otherwise, how can you use a program to get the coordinates of the car. Internet g, GPS
