AsteRx-m3 Fg is Septentrio’s best-in-class OEM board. It  is a multi-frequency multi-constellation GNSS receiver  featuring top positioning performance with flexibility  to be used either as a base station or as a rover. In dual  antenna mode it provides heading & pitch or heading  & roll information on top of reliable and accurate  positioning. This receiver is specifically designed for Fg  survey and construction with RTK as well as Fgstar PPP  high-accuracy 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

*High-accuracy positioning at sea with Fugro Fgstar PPP corrections 

Top performance in challenging environments 

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

The GNSS+ toolset is the technology that allows AsteRx-m3  Fg 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 Fg 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 Fg 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 Fg 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 Fg is compatible with GeoTagZ  Software and its SDK library for PPK (Post-processed kinematic)  offline processing.
