AsteRx-m3 Pro+ DevKit is Septentrio’s best-in-class versatile OEMboard DevKit.Itismulti-constellation GNSS receiver featuring top positioning performance with flexibility to be used either as a base station or a rover receiver. In dual antenna mode it provides he ading & pitch or heading & roll information on top of r eliable and accurate positioning.


KEY FEATURES

*Flexibility of use and easy-to-integrate

*Best-in-class SWaP (Size, Weight and Power)

*AIM+ anti-jamming and monitoring system

*Full-constellation, triple-frequency satellite tracking

*Sub-degree GNSS heading & pitch or heading & roll

*High update rate with low latency

 


Top performance in challenging environments

The AsteRx-m3 Pro+ is designed to deliver reliable and robust positions even in challenging environments.

The GNSS+ toolset is the technology that allows AsteRx-m3 Pro+ to be reliable also in challenging environments where the GNSS signal is disturbed or the receiver is subject to shocks and vibrations:

„LOCK+ for robust tracking during high vibrations and shocks

„APME+ to disentangle direct signal and those reflected from nearby structures

„IONO+ provides advanced protection against ionospheric disturbance

„AIM+ most advanced on-board anti-jamming and anti-spoofing technology in the market

 

BENEFITS

State of the art with flexibility of use  

The AsteRx-m3 Pro+ is a state-of-the-art GNSS receiver using  triple frequency and multi-constellation GNSS technology both  for maximal positioning availability and reliability in challenging  conditions. It can be used as a base station or a rover receiver  in single or dial antenna configuration. In dual antenna mode  GNSS heading provides unmatched performance in both  static and dynamic conditions removing the reliance on vehicle  dynamics or magnetic sensors.

Such a versatile receiver allows integrators to keep a single  item in stock which can be used in a multitude of applications.  During the manufacturing process the needed features can be activated depending on the intended application.


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 greater usability. 


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 GeoTagZ  Software and its SDK library for PPK (Post-processed kinematic)  offline processing.
