Septentrio AsteRx-i S UAS Receiver
The manufacturer has issued an end of life (EOL) notice for this product. Please see the EOL Notice Tab for more information.
The Septentrio AsteRx-i S UAS is a GNSS/INS receiver designed specifically for straightforward integration into unmanned aerial systems (UAS).
It provides centimeter-level RTK positioning and 3D attitude. Its 44 pin connector is compatible with 3rd party integrations, and it includes 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 Advanced Interference Monitoring and Mitigation system
- 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 and simple to integrate. 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 UASÂ 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 toolkit – converts 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 toolkit for best performance, the AsteRx-i S UAS provides reliable 3D attitude and positioning for the point of interest.
Interference RobustnessÂ
The AsteRx-i S UASÂ 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 UASÂ 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.
