Minimum distances for the GPS Antenna from a Radar Scanner
The GPS antenna should be installed where it has a clear "view" of the sky. The objective is that it should
"see" the horizon freely through 360° with a vertical observation sector of 5...90° above the horizon. Small
diameter obstructions, such as masts and booms, do not seriously degrade signal reception, but such
objects should not eclipse more than a few degrees of any given bearing.
Locate the antenna at least 3 m away from and out of the transmitting beam of high-power transmitters
(S-Band radar and/or Inmarsat systems). This includes the ship’s own AIS VHF antenna.
