Model AU-217
Ideal for use in difficult site enviorments including urban areas, weather and RF interference areas
The AU series is a GPS/GNSS antenna for Timing that is intended for installation on buildings. The AU-217 has excellent weather and interference resistance, and has the capability to filter radio waves that adversely affect the GNSS receiver (such as radio waves for broadcasting and satellite communications). The AU-217 is multi-constellation compatible and can receive signals including GPS (USA), GLONASS (Russia), Galileo (Europe) and QZSS (Japan). When combined with a GNSS receiver that supports these satellite constellations, it is also suitable for use in urban areas with poor sky visibility.

Drawing
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.
