How Long Does It Actually Take to Drive When the Navigation Says 8 Hours?
1 Answers
Navigation says 8 hours but it actually takes 5 hours to drive. Here is relevant information about car navigation: 1. Concept: A car navigation system is a driving assistance device that helps users accurately locate their current position, calculate the itinerary based on the set destination, and guide users to the destination through map display and voice prompts. 2. Operating Principle: GPS consists of three main parts: space satellites, ground monitoring, and user receivers. In space, 24 satellites form a distribution network, distributed in 6 quasi-synchronous orbits around the Earth at an altitude of 20,000 kilometers and an inclination angle of 55°, with 4 satellites in each orbit. GPS satellites orbit the Earth every 12 hours, enabling any location on Earth to simultaneously receive signals from 7 to 9 satellites.
