1. Beidou positioning
Beidou Satellite Navigation System is an independent satellite navigation system built and operated independently in China. It is an important space infrastructure for global users with all -time, full -day, high -precision positioning, navigation and timing services.
With the development of the construction and service capabilities of the Beidou system, related products have been widely used in transportation, marine fishery, hydrological monitoring, meteorological forecasting, surveying and mapping geographical information, forest fire prevention, communication during communication, power scheduling, disaster relief, emergency search and rescue and other fields and other fields , Gradually penetrate all aspects of human society's production and people's lives, injecting new vitality into global economic and social development.
2. Radar
The radar was born during the Second World War, from the position and distance of the simple measurement target to the current multiple functions. The radar has multiple functions, high -precision, miniaturization, high power, multi -target, signal, anti -interference and other functions. In addition to the phased array radar, the circular scan radar rely on the precise calibration of the antenna direction to determine the position of the target. So how is the target distance measured?
In fact, the principle is also very simple: radar launch -a pulse, reflects back after encountering the target, as long as the total time of the pulse back and forth, you can get the distance from the target to the radar station. That is: R = CT/2
In the formula: R is the distance from the radar station to the target; C is the speed of radio waves, 3*105km/sec; T is the time interval between pulse back and forth, 1 second = 103 milliseconds = 106 microsecond, this is the basic pulse test distance principle.
3. Global Positioning System GPS
GPS is a global, all -weather, continuous, and real -time high -precision navigation system provided by the U.S. military and Air Force. Started development and deployment in 1973, and was officially put into use in 1993. Its basic principle is to determine the three -dimensional coordinates of the measurement point through the position relationship of the three known points to the measurement point, and to correct it by multiple other known points.
