Three essential points when installing a GNSS antenna

When installing a GNSS antenna, components such as the coaxial cables and amplifiers should be selected to satisfy the antenna specifications of the GNSS receiver. It is also necessary to consider the propagation delay between the antenna and the receiver.  

In the following document, we explain how to calculate the required specification values with concrete examples from the viewpoint of a GNSS receiver manufacturers.

  • Total gain
  • Total NF
  • ropagation delay in coaxial cables

It is especially useful for those who are new to GNSS receivers. We have prepared an Excel tool for calculating "Total Gain" and "Total NF" due to their complex formulas.
