The AsteRx-U GNSS & heading receiver is nearing End of Life (EOL). Orders accepted until, and not later than February 29, 2024 (last time buy date, subject to availability) for configurations including North America 4G cell modem. Septentrio has released the new AsteRx-U3 as a replacement.



The Septentrio AsteRx-U is a powerful multi-frequency GNSS and heading receiver that is designed with usability, durability, and longevity in mind. It’s perfect for use in mining, construction, and agriculture applications, and includes features such as LOCK+ technology that cancels out the effects of severe vibrations, and IONO+ for industry-leading accuracy regardless of ionospheric activity. It can also filter out ambient RF interference to ensure clear reception at all times.

Using the AsteRx4 engine, the AsteRx-U can track and receive all currently-used GNSS navigation and correction constellations, and is designed to support future systems as well. You can interface with the receiver using any web-capable device thanks to an intuitive web portal that can communicate with the AsteRx-U by Wi-Fi, intranet, or USB.
