This article will explain in detail the application of satellite navigation and positioning system for you. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

At present, the relatively mature satellite navigation and positioning systems used are: the Global Positioning system GPS of the United States, the Gronas Satellite Navigation system GLONASS of Russia, the Galileo Satellite Navigation system GALILEO of the European Union and the Beidou Satellite Navigation system BDS of China.

Correlation

Satellite navigation system, also known as Global Navigation Satellite system (Global Navigation Satellite System,GNSS), is a space-based radio navigation and positioning system that can provide users with all-weather 3D coordinates, speed and time information on the earth's surface or anywhere in near-Earth space. Includes one or more satellite constellations and their enhanced systems needed to support specific tasks.

The four major satellite navigation system suppliers announced by the International Committee on Global Navigation Systems (ICG) include the Global Positioning system (GPS) of the United States, the Gronas Satellite Navigation system (GLONASS) of Russia, the Galileo Satellite Navigation system (GALILEO) of the European Union and the Beidou Satellite Navigation system (BDS) of China.

Application of satellite navigation and positioning system:

The global satellite navigation system is used in military, resources and environment, disaster prevention and mitigation, surveying and mapping, electric power telecommunications, urban management, engineering construction, mechanical control, transportation, agriculture, forestry, fishery and animal husbandry, archaeology, life, Internet of things, location services.

Navigation

For weapon navigation, can accurately guide missiles, cruise missiles; for vehicle navigation, can be used for route navigation, vehicle scheduling, monitoring system; for aircraft navigation for route navigation, approach landing control; for ship navigation, can be used for ocean navigation, port / inland water diversion; when personal travel and exploration can also be used for personal navigation.

Positioning

Can locate vehicles, mobile phones, PDA and other mobile devices, with equipment anti-theft, in tourism and field exploration can use electronic maps to check their location. Children or the elderly can also be located so that they can determine their exact location in time when they get lost.

Measure

By using the carrier phase difference technology (RTK) in the global satellite navigation system, its measurement accuracy can reach in centimeters. Compared with the traditional manual measurement, it has incomparable advantages over manual measurement, such as high accuracy, easy operation, portable measuring equipment, all-weather operation, no visibility between measuring points and so on. At present, global satellite positioning technology has been widely used in geodesy, crustal movement, resource exploration, cadastral survey and other fields.

Agriculture

Many countries have used the global satellite navigation system for agricultural development, which can locate farmland information, monitor yield, collect soil samples and so on, and then analyze and process the collected data through the computer system to formulate more scientific farmland management measures. The farmland information such as yield and soil status can also be loaded into the sprayer with GPS equipment, and its dosage can be accurately used in the process of fertilizing and spraying farmland, which can reduce the environmental pollution caused by fertilizers and pesticides.

rescue

The use of global satellite navigation and positioning technology can improve the response speed of various departments to traffic accidents, traffic jams, fires, floods, crime scenes and other emergencies. It can help rescue workers to rescue missing persons under adverse weather and geographical conditions.

Monitoring and management

The purpose of monitoring and management of the airport is to reduce the lag time of aircraft take-off and approach, and to effectively dispatch aircraft, vehicles and personnel. Global satellite navigation and positioning technology can provide all-weather, safe and precise navigation for all runways in any climatic environment. Aircraft using global satellite navigation and positioning technology can be made more flexible so that they can operate on their own when they are unmanned or off the runway, and the dispatching system can effectively organize ground traffic and deal with apron accidents.

Military Science

Modern war has evolved into an information war, relying on the global satellite positioning system can accurately guide missiles and bombs, thus guiding targets. At the same time, it has become an indispensable standard military equipment in infantry tactical operations. The global satellite navigation system is also of great significance for special operations, because it can be covertly located all-weather and continuously, and users can use it without emitting any signals as long as they can receive satellite signals. Therefore, in special operations, you can keep in touch with the command without radio silence, get tactical support without sending a signal, and can be changed at any time to confirm the ideal path of action.
