AsteRx RBi3 Pro GNSS/INS Receiver

Septentrio AsteRx RBi3 Pro+ GNSS INS receiver

Product Information

Rugged GNSS/INS Positioning for the Toughest Environments

The AsteRx RBi3 Pro is a high-performance multi-frequency GNSS/INS receiver designed to deliver reliable centimetre-level positioning, heading and orientation in the world’s most demanding operating environments.

Engineered for industrial, marine, construction, mining, defence and autonomous applications, the AsteRx RBi3 Pro combines advanced GNSS technology with an integrated Inertial Navigation System (INS) to maintain precise positioning where conventional GNSS receivers struggle. Its ultra-rugged housing withstands extreme temperatures, corrosive environments, shock and vibration, ensuring dependable performance wherever your operations take you.

Reliable Positioning When It Matters Most

Accurate positioning is critical in harsh environments where signal interruptions, vibration and interference are common. The AsteRx RBi3 Pro combines multi-frequency GNSS tracking with Septentrio’s advanced GNSS+ technologies to deliver continuous, high-accuracy positioning in challenging conditions.

Whether operating in heavy industry, offshore, urban canyons or remote environments, the receiver maintains reliable centimetre-level RTK performance, helping maximise productivity while reducing downtime.

Continuous Positioning with Integrated INS

The built-in Inertial Navigation System (INS) enhances positioning accuracy while providing precise orientation, roll and pitch information. When satellite signals are temporarily blocked by buildings, vegetation, bridges or other obstacles, the INS maintains a continuous position solution until GNSS signals are restored.

This seamless integration delivers:

  • Continuous positioning during temporary GNSS outages
  • Improved navigation in challenging environments
  • Precise orientation and motion data
  • Increased reliability for autonomous and dynamic applications

Precise GNSS Heading Without Magnetic Sensors

For applications requiring accurate heading, the optional dual-antenna configuration delivers instant, position-independent heading alongside centimetre-level RTK positioning.

Unlike magnetic compasses or systems that rely on vehicle movement, GNSS heading provides highly accurate orientation immediately after start-up and performs consistently in both static and dynamic conditions.

Ideal for autonomous vehicles, hydrographic surveying, marine navigation, machine control and mobile mapping applications.

Fast and Simple System Integration

The AsteRx RBi3 Pro is designed to integrate quickly into existing systems and workflows. Comprehensive documentation, open interfaces and powerful software tools simplify configuration, monitoring and application development.

Features include:

  • Fully documented communication interfaces
  • Extensive command and data message support
  • Intuitive Web User Interface (WebUI)
  • Powerful RxTools analysis and configuration software
  • Open architecture for rapid application development

The result is faster deployment, reduced development time and easier long-term system maintenance.

GNSS+ Technologies for Maximum Performance

The AsteRx RBi3 Pro incorporates Septentrio’s advanced GNSS+ technologies, delivering exceptional positioning performance in environments where signal quality is compromised.

LOCK+ – Reliable Tracking Under Shock and Vibration

Heavy machinery, rough terrain and constant vibration can disrupt satellite tracking. LOCK+ automatically adapts receiver settings in real time, maintaining reliable satellite tracking and continuous positioning even under severe mechanical stress.

IONO+ – Advanced Protection Against Ionospheric Disturbances

Space weather and ionospheric activity can significantly degrade GNSS accuracy or interrupt RTK positioning. Developed through years of experience supporting users in some of the world’s most ionospherically active regions, IONO+ provides industry-leading protection against ionospheric disturbances, helping maintain positioning accuracy and service availability.

APME+ – Superior Multipath Mitigation

Metal structures, buildings and reflective surfaces create multipath errors that reduce positioning accuracy. APME+ intelligently separates direct and reflected satellite signals, significantly improving measurement quality and positioning accuracy. For applications requiring maximum configuration flexibility, APME+ can also be disabled.

RAIM+ – Intelligent Integrity Monitoring

Receiver Autonomous Integrity Monitoring (RAIM+) continuously validates GNSS measurements, signal quality and navigation calculations. Faulty observations caused by multipath, ionospheric effects or other errors are automatically identified and removed, ensuring the highest possible confidence in every position solution.

AIM+ Anti-Jamming and RF Spectrum Monitoring

GNSS interference is becoming increasingly common in both civilian and industrial environments. The integrated AIM+ anti-jamming and RF spectrum monitoring system continuously detects and suppresses both intentional and unintentional interference before it affects positioning performance.

AIM+ automatically mitigates a wide range of RF threats, including:

  • Continuous narrowband jammers
  • Wideband interference
  • Pulsed transmitters
  • Inmarsat satellite communications
  • Iridium satellite transmissions

This intelligent protection enables the AsteRx RBi3 Pro to continue delivering reliable, high-accuracy positioning even in RF-congested environments.
