Introduction and application of Beidou timing systemBeidou timing System is the Chinese people's own satellite timing system, is the pride of our countrymen. Today XI ' an synchronous Electronic Technology Co., Ltd. take you to understand the Beidou timing system and application.1 introduction of Beidou satellite navigation systemBeidou time-based timing equipmen

Three Beidou Network School time serverBeidou Network School Time server is to receive the Beidou satellite standard clock signal, through the network port and serial output time information of a cost-effective time server, Beidou service server is widely used in finance, mobile communications, oil, electricity, transportation, industry and national defense and o

Recently in the commissioning of the GPS Beidou dual mode, has been debugging now, the following is a few words involved.GPS:GPS is the abbreviation for the English Global Positioning System (GPS). GPS started in 1958 with a U.S. military project, which was put into use in 1964. In the 1970s, the United States Armed Forces jointly developed a new generation of satellite positioning system GPS. The main objective is to provide real-time, 24x7 and globa

SYN2136 type Beidou NTP network time serverProduct OverviewSYN2136-type Beidou NTP network time server is designed by Xi ' an synchronous Electronic Technology Co., Ltd., self-developed and produced a time server based on the NTP/SNTP protocol, receive Beidou satellite signal, from the Beidou Earth geostationary satell

In view of the current situation of GPS system for U.S. military control, the UAV status monitoring system based on "Beidou" Satellite navigation system and wireless digital radio station, which has the ability of regional navigation and positioning in China, is studied. The system takes the MSP430 series processor as the control unit, uses the UM220 "Beidou" navigation receiver to obtain the status informa

GPS application and development of Beidou dual-mode technology -data structure extensionor from the Gps.h header file, first of all gpssvstatus structure needs to be modified, gpssvstatus at that time is designed to consider the storage of GPS satellite information, but we are now to store two-mode data, so we need to expand the structure, how to expand it?Of course, the price is small, can not be completely overturned, the author thought of is to inc

At that time, GpsSvStatus was designed to store gps satellite information, but now we nee

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 system, positioning speed greatly improved. China's self-developed

From: jgaoabc Space In connection with "modifying Beidou 4.1 shell with equivalent replacement code method", we continue to kill it. This is the Add flower command. The flower command we want to add is not common in the world, the flower instruction we added has the actual operation function and simulates some actions of the shell software. The main purpose is to make the soft killer confused. First, look for an empty area. After adding the

Research on Application and Development of GPS Beidou dual-mode Technology -- data parsing and gps Development In the previous article, we introduced several important concepts. Next we will parse this dual-mode output log. Before parsing, let's take a look at the significance of each important standard field. In actual development, the author only used four of them, namely GGA, GSA, GSV, RMC, and GLL. Of course, there are other fields that I think ar

, but its redundancy is 0, when the hard disk damage, The data is also damaged. In the production environment of the server, the most used is RAID5 or RAID6, which provides read and write performance, but also provides redundancy. RAID1 are often used in situations where the accuracy of the data is required and strictly.Let's summarize the pros and cons of each of these 4 commonly used RAID levels: RAID level Speed Redundancy of Disk Utilization RAID

To be honest, the default fonts in Linux, especially Chinese fonts, are not very nice in most releases. Therefore, installing the font becomes a necessary step after installing Linux on the desktop. But where does it start?
