GPS/GNSS Antennas

GPS Antenna (For Timing) Model GPA-014

Antenna for GPS, Galileo and QZSS L1 (1575.42MHz) reception.
Ideal for use in location with frequent/heavy snowfalls

The GPA series is a GPS/GNSS antenna for Timing that is intended for installation on buildings.
GPA-014B is designed to withstand harsh outdoor environments including rain, wind, sunlight and temperature changes, and is also equipped with a radome that prevents signal attenuation due to snow accumulation.

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.
