This guide details a generic instruction for the installation and operation of the  GpsDome module. This guide has been written for both static and in-vehicle application although GpsDome may be used in a range of applications.


GpsDome (see Figure 1) is a compact, light-weight GPS anti-jamming module, designed to prevent loss of position fix and time in the presence of certain types of jammer. The unit may be installed on a range of installations that rely on GPS and connects between the antenna and the GPS receiver.

Two active GPS antennas are connected to the SMA RF connectors; the primary and auxiliary antenna inputs. The RF Output provides connection to the input of the GPS Receiver.

  • The  GpsDome module should be mounted on a flat surface where possible and secured using the mounting holes provided.
  • To prevent damage to any cable assemblies used in this installation, ensure that cables are not bent, deformed or snagged to cause damage to the internal wiring or the connector ends.
  • This product is a high-tech electronics module; we recommend installation is undertaken by a professional.
  • During installation ensure there is NO power applied to the module. Make sure the GPS receiver is not powered.
