SS antennas consider the following e The space above the antennas has to be free of obstructions of any kind The antenna should be protected from direct illumination of radar beams and other transmitting antennas such as Inmarsat antennas Seapath is more sensitive to blocking and reflections multipath of GNSS signals than GNSS sensors which only utilise pseudo range data This since Seapath also utilises carrier phase measurements for heading determination and both GNSS antennas need to see at least four common satellites at the same time Caution The GNSS antennas have to be mounted in such a way that blocking of the GNSS signal avoided e In order to reduce problems due to multipath effects the GNSS antennas have to be mounted above the nearest deck at a height which is equal to the width of this deck or higher e The Antenna Bracket has to be mounted in such a way that torsion movement relative to the ship s hull is kept at an absolute minimum 30 Man techn seapath320 rev 1 Technical Description Note If the Antenna Bracket supplied by Kongsberg Seatex is not used it is important that the antennas are rigidly mounted so that the distance between the antennas does not change due to vibrations or accidental dislocation The antenna baseline length is recommended in the range 2 5 to 4 0 metres but 1 to 5 metres can be used Maximum heading accuracy is achieved at 4 0 metres baseline The maximum length for ea
