1 Answers
Press the navigation RST button for about 10 seconds to restore factory settings. Below is relevant information about car navigation systems: 1. Concept: A car navigation device is a driving assistance tool that helps users accurately determine their current location, calculates routes based on set destinations, and guides users to their destinations through map displays and voice prompts. 2. Operating Principle: GPS consists of three main components: space satellites, ground monitoring, and user receivers. In space, 24 satellites form a distributed network, positioned in 6 quasi-synchronous orbits around the Earth, each orbit 20,000 kilometers above the ground with an inclination angle of 55°. Each orbit contains 4 satellites. GPS satellites orbit the Earth every 12 hours, enabling any location on Earth to simultaneously receive signals from 7 to 9 satellites.
