As the earliest satellite navigation system, GPS enjoys wide popularity and application in the world, since 1973 began to develop, after the launch of the first satellite in 1978, the GPS system has been continuously improved and developed for many years, and has become one of the leaders in the field of global navigation.
The United States has widely promoted GPS, and there are many users around the world, and many countries use GPS in military and civilian equipment, without autonomous satellite navigation systems.
There is nothing wrong with such a practice in peacetime, but when relations are tense and the United States turns off the GPS, how many countries in the world can launch missiles normally? What is the level of China's Beidou system?
GPS system
As the first satellite navigation system established, the GPS system has made a major breakthrough in technology, laying the foundation for the subsequent development of satellite navigation system.
In the field of scientific research, GPS systems are widely used in research and experiments in earth science, atmospheric science and other fields, providing valuable data support for scientists.
In the aerospace field, the GPS system provides accurate navigation and positioning services for aircraft, improving flight safety and efficiency.
In the field of transportation, GPS systems are used in car navigation, ship navigation, etc., bringing revolutionary changes to the transportation industry.
During the Gulf War, the US-led multinational coalition carried out large-scale military operations against Iraq, and the GPS system played a key role in providing accurate navigation and positioning capabilities for the allied forces, effectively suppressing the missile threat of the Iraqi army.
By utilizing the GPS system, the US military is able to accurately determine its own location and accurately calculate the coordinates of the target, so as to achieve precision strikes and effective defense.
By monitoring and locating the movement of troops in real time, GPS provides the Allied Forces with superior battlefield management and military operations support capabilities, enabling better coordination of operations, deployment of resources, and improved combat efficiency and battlefield command capabilities.
The successful application of the GPS system in the Gulf War not only strengthened the combat effectiveness of the US military, but also demonstrated to the world the important role of GPS technology in the military field.
Some countries are beginning to realize that over-reliance on GPS systems may put them in a passive position in war, as the United States can limit military operations in other countries by controlling GPS signals.
As a result, they took action, determined to build their own satellite navigation system to reduce their reliance on GPS and ensure that they had independent navigation and positioning capabilities in the event of war. Russia and China are two of the most prominent examples.
GLONASS system
During the Cold War, the Soviet government was working on the development of a satellite navigation system independent of the American GPS system, and in 1985, the GLONASS system was officially launched, becoming an important strategic project of the Soviet military.
Within two years of the launch of the GLONASS system, the Soviet Union successively launched 30 satellites, which were distributed in Earth orbit and covered the whole world, laying an important technical and space foundation for the improvement and expansion of the subsequent system.
In the early 90s, due to the economic difficulties and political turmoil brought about by the collapse of the Soviet Union, the construction of the GLONASS system came to a standstill and was even on the verge of paralysis.
However, the Russian government realized the strategic importance of the GLONASS system and took a series of measures to restart and accelerate the construction of the system.
With the gradual recovery of the Russian economy and the improvement of science and technology, the GLONASS system has gradually regained its vitality and ushered in new development opportunities at the beginning of the 21st century.
The Russian government's increasing investment in the GLONASS system has accelerated the updating of satellites and the upgrading of the system, making it play an increasingly important role in the global satellite navigation system.
In 1995, the Russian government invested more than $3 billion in the completion of the networking, which enabled the GLONASS system to be fully upgraded and improved.
As an important member of the global navigation system, the GLONASS system has been further expanded and deepened in the fields of military, civilian and scientific research. The Russian government is also actively cooperating with other countries to promote the interconnection of GLONASS with other satellite navigation systems.
Due to the wide coverage and stable signal of the GLONASS system, Russia will not be affected by the limitations of the US GPS system in the event of an emergency such as the outbreak of war.
This independence and autonomy provides an important guarantee for Russia's defense and security, ensuring its combat capability in wartime.
Beidou system
In 2020, China's Beidou satellite navigation system was officially launched, which not only brought practical benefits to global users, but also marked the improvement of China's technological strength and global influence in the aerospace field.
The Beidou system has achieved a breakthrough in technology, and its positioning accuracy has reached the centimeter level, and users can obtain very accurate location information, which meets the needs of high-precision positioning in various fields.
This is of great significance to transportation, aerospace, geographic surveying and mapping and other fields, and provides strong support for the development of related industries.
Whether on land, at sea or in the air, the Beidou system can provide timely and accurate location information, provide technical support and guarantee for scientific research actions, and help improve the efficiency and success rate of scientific research.
In the military field, the Beidou system provides high-precision positioning and navigation services for military troops, which can meet the needs of military forces for precise positioning and ensure that troops can accurately arrive at their destinations at any place and at any time.
During military operations, the enemy will use jamming means to disrupt the normal operation of the satellite navigation system and affect the positioning and navigation of the troops.
The Beidou system has strong anti-jamming capabilities, and can maintain stable positioning and navigation services in the face of jamming, ensuring that the combat effectiveness of the troops will not be affected.
The role of the Beidou system in the military field cannot be ignored, improving the combat effectiveness and battlefield survivability of the troops, and with the continuous innovation and improvement of the Beidou system in technology, its position and role in the military field will be further strengthened and expanded.
In addition, the Beidou system is also open to other countries, promoting the development of the global satellite navigation field, building a global navigation network, and providing more diversified and reliable navigation services for global users.
Continental has signed satellite navigation cooperation agreements with many countries around the world, proving the advantages of the Beidou system in terms of technical performance and service quality, and can provide users with more stable and reliable navigation services, so that users are not affected by GPS system interference.
In the future, China will continue to promote the technological innovation and application expansion of the Beidou system, strengthen international cooperation, further enhance the status and influence of the Beidou system in the field of global satellite navigation, reduce the risk of being threatened by the GPS system, and protect its own security.
