Highly accurate positioning packaged in a small, industrial-grade housing is now within reach for a wide range of automation and navigation use cases.Mobile roboticsWarehouse logisticsLarge-scale industrial automation

It also suits surveying workflows, precision agriculture, UAV operations, and marine navigation where reliable positioning and heading are required.

GNSS Technology for Compact Industrial Positioning

Septentrio, a Hexagon company, has introduced AsteRx EB, a housed, multi-frequency unit that delivers uncompromised precision and dependable heading for use cases such as:Industrial robotsPort operationsMaritime platformsScalable automation

The IP67-rated enclosure protects the electronics against weather, dust, and spray, while advanced GNSS+ technologies sustain performance where satellite signals are stressed by tree canopy, reflective surfaces, interference, and multipath. GNSS+ is Septentrio’s umbrella for receiver-level resilience and quality features, including AIM+ for anti-jamming (detecting and mitigating interference so tracking can continue), multipath mitigation (reducing errors from reflected signals), interference monitoring (observing and reporting RF conditions to support diagnostics and hardening), and pulse blanking (suppressing brief, high-energy interference bursts at the front end so they do not corrupt tracking). RAIM+ integrity monitoring validates the positioning solution by checking measurement consistency across satellites and flagging solutions that do not meet integrity expectations, which is vital for autonomous navigation.

AIM+ (Advanced Interference Mitigation) is the receiver’s anti-jamming system designed to maintain positioning availability when intentional or unintentional RF interference is present. In practical terms, it works by continuously sensing interference characteristics and applying mitigation strategies (such as adaptive filtering and, where appropriate, pulse blanking) to protect satellite signal tracking. The benefit is more stable positioning and heading in electrically noisy industrial environments, fewer dropouts, and better continuity for automation systems that depend on consistent GNSS.

For integration, Septentrio receivers commonly support interfaces such as Ethernet, USB, serial ports (for example RS-232/RS-422), and CAN, with wireless options such as Bluetooth or Wi-Fi available on select setups or via external gateways. They also typically provide standard GNSS data and correction streams (for example NMEA and RTCM) as well as timing and event features such as PPS and event marker inputs, depending on configuration.

Position accuracy depends on the correction method and operating conditions; typical performance ranges from meter-level standalone GNSS, to decimeter or sub-meter positioning with SBAS, to centimeter-level RTK (often on the order of 1–2 cm horizontal and 2–3 cm vertical in good conditions). For high-precision automation, RTK corrections are commonly used to achieve repeatable lane-level and docking-grade results.

To receive RTK corrections via NTRIP (Networked Transport of RTCM via Internet Protocol), connect the receiver to an IP network (for example through Ethernet or a Wi-Fi/cellular router), then configure the NTRIP client settings in the receiver’s configuration interface: enter the caster address and port, select the mountpoint, and provide credentials if required. Choose the appropriate RTCM stream, start the NTRIP session, and verify the receiver reports that corrections are being received and that the solution mode transitions to an RTK-fixed or equivalent high-precision state.

Firmware upgrades are typically done by first obtaining the correct firmware package for the exact receiver model from Septentrio’s official product/support download area, then backing up the current configuration, and ensuring stable power for the entire update. Upload and apply the firmware using the receiver’s management interface or configuration tooling, allow the receiver to reboot, and finally confirm the new firmware version and restore or validate settings before returning the unit to service.

Product datasheets are available from Septentrio’s official product pages and download/support sections: navigate to the specific receiver model page (for example AsteRx EB) and download the datasheet PDF from the documents or downloads area.

To access the command line interface (cli), connect using a supported management channel such as a direct serial connection (using a terminal application with the configured port settings) or a network session such as SSH or Telnet when enabled on the device. After establishing the session and authenticating if required, you can issue configuration and status commands for monitoring, logging, and system setup.In industrial automation, resilient receiver technologies that detect, mitigate, and report interference can be as important as raw accuracy, because uptime and integrity drive safety and throughput.

Receiver Perspective: Scale With Confidence

AsteRx EB is the right boxed receiver for teams that need reliable, robust, and highly precise positioning in a small package at a cost that makes quick scaling feasible, said Danilo Sabbatini, Product Manager at Septentrio, a Hexagon company.
