The AsteRx-m3 Pro is a compact, high performance, ultra-low power GNSS receiver ideal for integration into robotics and other demanding industrial applications where power and space are at a premium. It incorporates the latest anti-jamming technology and offers unbeatable robustness and reliability.


KEY FEATURES

* Reliable and robust centimeter-level (RTK)

* AIM+ industry-leading anti-jamming, anti- spoofing technology

* OSNMA Support

* Industry-leading ultra-low power consumption

* Multi-constellation, multi-frequency satellite tracking

* Easy-to-integrate

 

Rover applications

The AsteRx-m3 Pro is a rover GNSS receiver with best-in-class positioning performance, with Septentrio's latest multi-frequency multi-constellation RTK technology. It delivers robust and reliable positions in challenging environment in both single and dual antenna modes. Its specialized design makes it easy to use and cost efficient as a rover receiver.


BENEFITS

State of the art

The AsteRx-m3 Pro is a state-of-the-art GNSS rover receiver designed to deliver reliable and robust position in challenging environments. The GNSS+ toolset is the technology that allows AsteRx-m3 Pro to deliver reliable positions even GNSS signals are disturbed or when the receiver is subject to shocks and vibrations:

* LOCK+ enables robust tracking during high vibrations and shocks 

* APME+ disentangles direct signal and those reflected from nearby structure 

* IONO+ provides advanced protection against ionospheric disturbance 

* AIM+ is the most advanced anti-jamming, anti-spoofing on-board interference mitigation technology on the market (narrow and wide band, chirp jammers).


Ultra-low power design

The AsteRx-m3 Pro provides RTK positioning at the lowest power consumption of any comparable device on the market. This means longer operation on a single battery charge, smaller batteries and improved efficiency.


Easy-to-integrate

The AsteRx-m3 Pro comes with fully documented interfaces, commands and data messages. The included RxTools software allows receiver configuration and monitoring as well as data logging and analysis. An SDK is provided, which allows integrators to create professional custom post-processing applications. AsteRx-m3 Pro is compatible with its SDK library for PPK (Post-processed kinematic) offline processing.
