Key features

  • Reliable and accurate IMU-enhanced GNSS positioning down to the cm level 

  • Full attitude - heading pitch and roll

  • Lightweight, low power and compact

  • AIM+ interference monitoring and mitigation system

  • High-update rate, low-latency positioning and attitude

Designed for demanding requirements for size, weight and power consumption, the AsteRx-i V is ideal for applications such as inspection with UAV's, UAS photogrammetry, automation, robotics and logistics. 

Intuitive tools and web user interface


The AsteRx-i V includes an intuitive on-board web user interface and a desktop tool set 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.

Unique low power consumption


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

The GNSS+ toolkit - converting 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 and of the dual antenna GNSS heading initialisation, the AsteRx-i V provides reliable 3D attitude and positioning for the POI (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. The AsteRx-i V can 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.



The AsteRx-i V 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 V applicability to automation, robotics and logistics.
