  • Page 25 Installation If the antenna is installed in a poor location, it can suffer from masking, multipath or interference from other radio sources which can affect the position performance. Masking The GNSS antenna should have an unobstructed line of sight to the sky. The signals from the satellite propagate by line-of-sight, which means that if the antenna cannot see the satellite, the reception will be severely impaired, if it occurs at all.
  • Page 26 Kongsberg 3710 DGNSS Receiver Figure 3 Bad antenna location, typically masking situation Multipath Inappropriate location of the antenna can result in the antenna receiving reflections of the incoming signal as well as the signal itself (multipath). The reflected multipath signal takes a longer path than the direct signal, introducing an error into the position calculation.
  • Page 27 Installation Interference from other radiating sources Interference can be caused by close proximity to other radiating sources. Installing DGNSS antennas in close proximity to satellite communication systems operating in or nearby DGNSS frequency bands (1.525 to 1.559 GHz) should be avoided (i.e. Sat C, Iridium).

  • Page 28: Receiver Unit

    Kongsberg 3710 DGNSS Receiver During installation, comprehensive tests should be carried out for potential interference by conducting transmissions from each RF source for extended periods, individually and simultaneously. Antenna location Antenna location is critical to system performance. When installing the antenna, note the following: •...

  • Page 29: Dgnss Antenna And Cable Installation

    Installation It should also be noted that a too powerful signal may cause saturation of receiving circuitry in shorter cable runs, making it necessary to use signal attenuators or cables with higher attenuation levels. Sharp bends, kinks and unnecessary connections should be avoided. External connections should be appropriately treated with self-amalgamating tape other preparations to keep out water.

  • Page 30: Electrical Installation

    Kongsberg 3710 DGNSS Receiver Wrap outdoor cable connections with waterproof self-vulcanising tape. An alternate way of waterproofing is to use heat shrink hose with glue. The hose should cover the whole connector and part of the cable. Secure the cable to the mast every one to three metres with clamps or bands.
