AsteRx-i3 D Pro

Ready-to-use GNSS/INS single-board receiver

  • Quad-constellation, multi-frequency, all-in-view RTK positioning
  • Reliable and accurate IMU-enhanced GNSS positioning down to the centimeter level
  • Single GNSS antenna with heading, pitch and roll
  • Lightweight, low power and compact
  • AIM+ unique interference monitoring and mitigation system + advanced other GNSS+ algorithms 

AsteRx-i3 D Pro delivers reliable centimeter level positioning combined with 3D orientation (heading, pitch and roll) in demanding environments. Its onboard inertial sensor provides orientation and positional dead-reckoning, making it ideal for systems that require continuous positioning even during short GNSS outages.

The AsteRx-i3 D Pro is a state-of-the-art GNSS/INS rover receiver designed to provide robust and reliable positioning and 3D attitude for the most challenging industrial applications. Septentrio’s multi-constellation, multi-frequency, accurate and reliable RTK is further enhanced by a powerful GNSS/INS integration that allows to have accurate heading, pitch and roll using a single antenna for the most efficient and lean integration.

Septentrio reliable centimeter-level positioning is based on true multi-frequency, multi-constellation GNSS (GPS, GLONASS, Galileo, BeiDou, QZSS) technology. AsteRx-i3 D Pro combines GPS/GNSS and an industry-grade IMU (Inertial Measurement Unit) to deliver precise positioning together with 3D attitude (heading, roll, pitch). Septentrio’s unique GNSS – IMU integration algorithm enables continuous positioning in environments of low satellite visibility where short GNSS outages are possible. This is referred to as dead reckoning or coasting and can happen near high structures, under bridges or under thick foliage. This makes AsteRx-i3 D Pro a robust positioning solution for machinery operating in environments challenging for GNSS, such as in container yards, urban canyons or near cliffs.

Mechanical vibrations or shocks caused by rough terrain can wreak havoc with satellite tracking. LOCK+ automatically adjusts the parameters of this receiver so you never lose position. 

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 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. 

AIM+ anti-jamming and RF spectrum monitoring system 

AIM+ offers built-in protection against intentional and unintentional jamming using a sophisticated system of sampling and mitigation mechanisms. Your high-precision GNSS receiver can automatically suppress the widest variety of interferers from simple continuous narrow-band signals to the more complex wide band and pulsed transmitters as well as lnmarsat and Iridium satellite transmissions
