Chapter 1: Introducing the A325 Smart Antenna
A325 Overview
The A325™ Smart Antenna offers an affordable, portable solution with professional level accuracy
for agricultural, marine, GIS mapping, and other applications powered by Hemisphere GNSS’
Eclipse™ multifrequency GNSS receiver technology.
Note:
Throughout the rest of this manual, the A325 Smart Antenna is referred to simply as the A325.

The A325 allows you to focus on the job at hand with fast startup and reacquisition times as well as
an easy-to-see LED status indicator for power, GNSS, and Bluetooth. With a durable enclosure that
houses both antenna and receiver, the A325 can be powered through various sources making it
ideal for a variety of applications. Dual- serial, CAN, and pulse output options make this GNSS
receiver compatible with almost any interface. Mount the A325 on a variety of roving machines and
vehicles for kinematic positioning and navigation applications.
RTK performance is scalable with A325—utilize the same centimeter-level accuracy in either L1-only
mode, or employ the full performance of fast RTK performance over long distances with L1/L2 GNSS
signals. Hemisphere GNSS’ exclusive SureTrack
®
technology ensures your RTK rover is making use of
every satellite it is tracking, even satellites not tracked at the base. Benefit from fewer RTK dropouts
in congested environments, faster reacquisitions, and more robust solutions due to better cycle slip
detection. SureTrack also removes concerns with mixing GNSS data from various manufacturers.
Even if your base is only L1/L2 GPS, SureTrack with GLONASS at your rover delivers complete GNSS
performance.
