GNSS Signal Structures

GNSS (Global Navigation Satellite System) signal structures refer to the way information is transmitted from satellites to receivers on the ground. These signals include a carrier wave, modulated by data that provides timing and satellite identity. The signals typically consist of a repeating pattern of bits encoded with precise timing information, allowing receivers to determine their position based on the signals' travel time. Different GNSS systems (like GPS, Galileo, GLONASS) use unique codes and frequencies, but all share a structure designed for accurate, reliable positioning and timing worldwide.
