GNSS Channels: What are and why are they so relevant?
Definition and Usefulness In general, GNSS geopositioning satellites emit signals consisting of three parts. A carrier signal, one or more pseudorandom noise codes (PRNs), and a navigation message. The last two are modulated by the carrier using a technique known as phase modulation. LGNSS channels allow the antenna of a GNSS receiver to detect the signal coming from a given...
