AsteRx-i S

AsteRx-i S integrates high-quality data, from the single or dual antenna multi-frequency AsteRx GNSS receiver with IMU measurements to generate an accurate and reliable position and orientation.

AsteRx-i S

Key features

  • Reliable and accurate IMU-enhanced GNSS positioning down to the cm level 
  • Full attitude - heading pitch and roll
  • Ultra-lightweight, low-power and compact
  • AIM+ Advanced Interference Monitoring and Mitigation system
  • High update rate, low-latency positioning and attitude
  • Robust calibration for wide temperature ranges

Designed for demanding requirements for size, weight and power consumption, the AsteRx-i S is ideal for applications such as unmanned ground vehicles, automation, robotics and logistics. 

The GNSS+ toolkit - converts bad environments into good positioning and orientation

Septentrio’s quad-constellation, multi-frequency, accurate and reliable RTK is further enhanced by a powerful GNSS/INS integration. Benefiting from Septentrio’s GNSS+ toolkit for best performance, the AsteRx-i S provides reliable 3D attitude and positioning for the point of interest.

AIM+ anti-jamming and RF spectrum monitoring system



AIM+, Advanced Interference Monitoring and mitigation, offers built-in protection against intentional and unintentional jamming and spoofing using a sophisticated system of sampling and mitigation mechanisms. In robotic devices neighboring electronics can produce radiofrequency radiation which interferes with GNSS signals. AIM+ offers protection against such interference resulting in faster set-up time and robust continuous operation. A built in spectrum plot allows you to analyze interference and locate interference. The AsteRx-i S can suppress the widest variety of interferers from simple continuous narrow-band signals to the complex wide band and pulsed transmitters.

Unique low power consumption


Septentrio’s core hardware technology allows the AsteRx-i S to be the market-leader in low power consumption. Consuming typically 1.5 W and having a unique total weight of 38 g (IMU + GNSS receiver), the AsteRx-i is ideal for robotic devices where space and payload are at a premium.



AsteRx-i S placement

The AsteRx-i S allows flexibility of the IMU placement separate from the GNSS receiver, allowing you to optimize space for tight integrations. The versatility of design and range of connection interfaces extend the AsteRx-i S applicability to automation, robotics and logistics.
