The A320™/A321™ Smart Antennas offer versatile, portable solutions with centimeter-level accuracy powered by Eclipse™ II multifrequency GNSS receiver technology. With the Eclipse II GNSS OEM module, RTK performance is scalable. 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. SureTrack™ technology gives peace of mind knowing 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 where others cannot. The durable enclosures house the receivers, antennas and optional radio modems, all in one package.
