What is a Navigation Assistance System?
1 Answers
Navigation assistance system refers to the application of GPS via commercial communication satellites for vehicle navigation, providing route guidance for drivers, thus forming an in-car navigation system. On the other hand, traditional maps often fail to keep up with street changes and are difficult to interpret, frequently leaving drivers without accurate instructions. Therefore, satellite navigation systems that utilize high-altitude satellite signals can provide precise and timely navigation and positioning for vehicles. More information about GPS is as follows: 1. Definition of GPS: GPS is a high-precision radio navigation positioning system based on artificial Earth satellites, capable of providing accurate geographical location, vehicle speed, and precise time information anywhere on the globe and in near-Earth space. 2. Classification: The ground monitoring segment consists of five ground stations distributed worldwide, which can be functionally categorized into monitoring stations, master control stations, and injection stations.
