Features of GPS System

????

????1. Global, 24/7 work:

????Can provide users with continuous, real-time three-dimensional position, three-dimensional speed and precise time. Not affected by weather.

????2. High positioning accuracy:

????The positioning accuracy of a single machine is better than 10 meters, and the differential positioning is adopted, and the accuracy can reach centimeter and millimeter levels.

????3. Multiple functions and wide application:

????With the deepening of people's understanding of GPS, GPS has not only been widely used in measurement, navigation, speed measurement, timing measurement, etc., but also its application fields have been continuously expanded.

????Classification of GPS Navigation:

????Vehicle type - used for vehicle navigation and positioning;

????Nautical - used for ship navigation and positioning;

????Aviation type - used for aircraft navigation and positioning. Due to the high speed of the aircraft, the receiver used in aviation is required to be able to adapt to high-speed motion.

????Spaceborne type - used for satellite navigation and positioning. Since the speed of the satellite is as high as 7km/s or more, the requirements for the receiver are higher
