EQUIPMENT DETAILS

Topcon PN-A5 is a high-end geodetic GNSS antenna designed for reference networks, permanent monitoring stations, and high-accuracy geospatial applications. The antenna combines Topcon’s TA-5 full-spectrum GNSS antenna element with an innovative semi-hemispherical convex impedance ground plane for improved multipath mitigation and stable low-elevation satellite tracking.

Using an array of vertical convex dipoles, the PN-A5 provides highly sensitive Full Wave tracking technology for existing and future GNSS constellations. The advanced impedance ground plane minimizes signal loss to the horizon while improving phase center stability across the GNSS frequency spectrum.

Designed for demanding environmental conditions, the antenna features IP67 protection, MIL-STD-810G compliance, and a rugged sealed construction for reliable long-term operation in infrastructure monitoring and geodetic network installations.
