Built around Septentrio’s latest ASIC, the GReCo4, it features built-in jamming detection and countermeasures, multi-path rejection and fast acquisition. It is accurate and reliable now and into the future with over 500 channels to track all available constellations (GPS, GLONASS, Galileo, BeiDou, NavIC and QZSS) and has many of Septentrio’s special GNSS+ algorithms (see further below).
Compact and portable, the AsteRx-U was developed with machine control users in the agricultural, construction and mining industries in mind. With the help of augmentation RTK or SECORX-S or Marinestar PPP service, users can benefit from centimeter and sub-decimeter positioning accuracy.
The receiver is configurable from any device from a web browser and there is no longer need for additional equipment such as spectrum analyzer, modem and UHF radio because Septentrio has developed all these features into the AsteRx-U.
- 544 channels for tracking all known and future signals from GPS, GLONASS, GALILEO, BEIDOU, NavIC, QZSS & SBAS on both antennas
- Precise and solid heading calculation
- centimetre-level (RTK) and dm-level (PPP) position accuracy
- Compatible with PPP, SSR, RTK and SBAS corrections
- Septentrio GNSS+ algorithms for solid performance even in regions of evaluated ionospheric activity
- Integrated cellular modem, Bluetooth and WiFi; optional UHF radio
The GNSS+ toolkit - converting bad environments into good positioning
Activity in the ionosphere is a problem for GNSS signals, from loss of RTK fix to total loss of signal lock. Having honed our skills, supporting applications in the most iono-active areas on Earth, the result is IONO+: the most advanced protection against ionospheric disturbances to GNSS signals on any receiver.
Metal and large nearby structures can reflect GNSS signals and produce multipath. The Advanced Multipath Mitigation Technology (APME+) system effectively disentangles direct and reflected signals enhancing both position and measurement quality. APME+ is bias free and, in line with Septentrio’s commitment to maximum configurability, can be disabled.
Advanced Receiver Autonomous Integrity Monitoring (RAIM+) comprises fault detection mechanisms of the receiver at all the levels including the generation of measurements, quality control and navigation algorithms. Detected faulty measurements, which are typically caused by high multipath or active ionosphere, are removed from the solution.
Mechanical vibrations or shocks caused by rough terrain can wreak havoc with satellite tracking. LOCK+ automatically adjusts the parameters of the AsteRx4 high-precision GNSS receiver so you never lose position.
AIM+ anti-jamming and RF spectrum monitoring system
All Septentrio high-precision GPS/GNSS receivers feature AIM+, the most advanced onboard radio frequency interference (RFI) monitoring and mitigation technology on the market. It can suppress the widest variety of interferers, from simple continuous narrowband signals to the most complex wideband and pulsed jammers. The built-in protection against intentional and unintentional jamming and spoofing uses a sophisticated system of sampling and mitigation mechanisms. The RF spectrum can be viewed in real-time in both time and frequency domains.
Intuitive web user interface
With your high-precision GPS reference receiver comes an intuitive web user interface for easy operation and monitoring allowing you to control the receiver from any mobile device or computer. The web interface also uses easy-to-read quality indicators ideal to monitor the receiver operation during the job at hand.
