Topcon introduces the PN-A5 GNSS antenna

Innovative convex impedance ground plane, improved multipath mitigation

LIVERMORE, Calif.  – February 23, 2012 – Topcon Positioning Systems (TPS) announces the new PN-A5 GNSS antenna that combines the company’s TA-5 full spectrum GNSS antenna element with a newly designed semi-hemispherical convex impedance ground plane.
This unique ground plane design provides improved multipath mitigation and a significant increase in ability to track signals from satellites located near to the horizon, according to company sources.
Utilizing Topcon’s new TA-5 antenna technology, the PN-A5 provides “full wave” signal tracking for all existing and planned GNSS signals by utilizing vertical dipoles for sensitive and stable signal reception.
This best-in-class geodetic antenna has an IPX7 waterproof and IP6X dustproof rating. It is ideally designed to meet the evolving requirements for reference network and infrastructure monitoring applications, according to company sources.
