The S321 is Hemisphere’s all-new multi-GNSS, multi-frequency, smart antenna. The S321 provides a robust performance and high precision in a compact and rugged package. With multiple wireless communications ports and an open GNSS interface, the S321 can be used in a variety of operating modes. Use the S321 as a precise base station sending RTK to your existing rover network. Turn S321 into a lightweight and easy to use rover by connecting it to your base via UHF radio or Wi-Fi network. The built-in web user interface can be used to control and manage the receiver status and operation, as well as to upgrade the S321 with new firmware and activations. S321 is Athena-enabled and Atlas- capable. To know more, click here..

Key S321 GNSS Survey Smart Antenna advantages:

  • Powered by the Athena RTK (Real time kinematic) technology.
  • With multiple connectivity options, the S321 allows for RTK corrections to be received over radio, cell modem, Wi-Fi, Bluetooth, or serial connection.
  • The S321 receiver also enables users to work with the Atlas service.


R330 GNSS Receiver

The R330™ GNSS receiver is a full solution product in a compact enclosure. The R330 utilizes Hemisphere GNSS’ Eclipse™ platform, and our latest GNSS patented technology. The R330 provides accurate positioning using several differential correction methods such as RTK, L-Band DGNSS (VBS/HP/XP/ G2), Beacon, and SBAS. Our MFA DGNSS patented technology allows the R330 to smoothly transition between DGNSS systems.

The R330 GNSS receiver works well in any marine or land application where positioning accuracy is required. The base unit is configured with L1, 10 Hz, SBAS, and raw data. The fully-upgraded unit can be optionally subscribed
to L1/L2 GNSS, 20 Hz, RTK, L-Band, Beacon, and SBAS. Compatible GNSS antennas for the R330 are A21™, A31™, A42™, A43™, and A52™.

The new R330 GNSS receiver will outperform its predecessors and provides a user-friendly experience. It features Hemisphere GNSS’ exclusive SureTrack™ technology that enables the receiver to model the phase on satellites the rover is tracking, allowing the operator to continue working without corrections from the base.

Key R330 GNSS Receiver Advantages:

  • Long-range RTK baselines of up to 50 km.
  • High-accuracy positioning in RTK, GNSS, SBAS, Beacon, and L-Band.
  • Fast update rate of up to 20 Hz providing the best guidance and machine control.
  • Status LEDs and menu system make R330 easy to monitor and configure.
  • Uses standard USB flash drive for data logging.





A325_GNSS Smart Antenna

A325 GNSS Smart Antenna

With A325, RTK performance is scalable. Utilize the 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.

Our exclusive 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. Rely on SureTrack technology from Hemisphere GPS. To view more information, click here..

Key A325 Smart Antenna Advantages:

  • Improved GNSS performance, particularly with RTK and GLONASS applications through the implementation of SureTrack technology.
  • Long range RTK baselines of up to 50 km.
  • L-band DGNSS/HP/XP capable 
  • Very fast RTK fix and reacquisition times.
  • Strong multipath mitigation and interference rejection.
  • Wide operating voltage range, 7-36 V, high transient protection for any power source.
  • Supports NMEA 2000 over Controller Area Network (CAN) for ISO bus connections.
  • Integrated 2D tilt sensor enables offset corrections.
