AsteRx-i S UAS

GNSS/INS positioning and attitude receiver designed for easy UAS integration


The AsteRx-i S UAS is a GNSS/INS receiver specifically designed for straightforward integration into Unmanned Aerial Systems (UAS).  It provides centimeter-level RTK positioning and 3D attitude. It features a 44 pin connector compatible with 3rd party integrations, as well as event marker inputs to accurately time stamp camera shutter events.


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+ unique interference monitoring and mitigation system + advanced GNSS+ algorithms
  • High update rate, low-latency positioning and attitude
  • Robust calibration for wide temperature ranges
  • Camera shutter synchronization

AsteRx-i S is also available as an OEM board for more generic integrations. 

Compact and versatile

The AsteRx-i S UAS hosts an on-board IMU for ease of integration. However the user has the flexibility to tether this IMU and install it in any other location. The compact form, light weight and low power consumption of AsteRx-i S UAS was designed to optimize battery life of aerial devices.

Designed for UAS

The AsteRx-i S UAS  is designed for easy integration into any UAS. The wide 4.5-30 V input power range allows powering the receiver directly from the UAS power bus. Event markers can accurately synchronize a camera shutter with GNSS time. The 44 pin connector, compatible with 3rd party integrations, makes it easy to integrate the AsteRx-i S UAS in existing platforms.

The GNSS+ technologies convert bad environments into good positioning and orientation

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

Interference Robustness 

The AsteRx-i S UAS  features 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 RF radiation which interferes with GNSS signals. AIM+ offers protection against such interference resulting in faster set-up time and robust continuous operation.




Ultra-low power design

The AsteRx-i S UAS  provides INS positioning at the lowest power consumption of any comparable device on the market. This means lower heat dissipation, simpler integrations and longer operation on a single battery charge.
