Navigational purpose band

WebIntroduction. The GNSS satellites continuously transmit navigation signals in two or more frequencies in L band. These signals contain ranging codes and navigation data to allow the users to compute the travelling time from satellite to receiver and the satellite coordinates at any epoch. The main signal components are described as follows: Web3 The typical navigation buoy is taken as 5.0 m2 for X-Band and 0.5 m2 for S-Band; for typical channel markers, with an RCS of 1.0 m2 (X-band) and 0.1 m2 (S-band) and height of 1 metre, a detection range of 2.0 and 1.0 NM respectively. 4 RCS for 10 m small vessel taken as 2.5 m2 for X-Band and 1.4 m2 for S-Band (taken as a complex target).
