This is an evaluation kit designed for rapid prototyping  of GNSS heading module mosaic-H. With dual-antenna  input, mosaic-go heading provides precise and  reliable heading combined with centimeter-level RTK  positioning. Dual antenna capability opens the door  to advanced automation and navigation performance  in both static and dynamic states, with reduced power  consumption. Dual antenna GNSS delivers heading  & pitch or heading & roll angles, which are available  immediately at start-up, helping initilize inertial sensors  which rely on movement for attitude measurements.


KEY FEATURES

*Dual antenna support for sub-degree heading & pitch or heading & roll angles

* All-in-view satellite tracking: multi-constellation, multi-frequency

* Best-in-class RTK performance

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

* OSNMA Support

* Lowest power consumption on the market

* Ready to use interface with USB, serial ports, PPS and events

 

BENEFITS

Reliable heading performance

With dual-antenna input, mosaic-go heading provides  precise, reliable and position independent heading combined  with centimeter-level RTK. GNSS heading provides the best  performance in both static and dynamic conditions removing the  reliance on vehicle movent for INS initialization. It also provides  an alternative to magnet-based heading sensors, which can be  effected by metal.


Advanced technologies inside

Septentrio’s GNSS+ toolset enables accuracy and reliability in the toughest conditions, allowing you to complete projects with the highest quality and efficiency. It includes:

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

*LOCK+ for robust tracking during high vibrations and shocks.

*APME+ multipath mitigation to disentangle direct signal and those reflected from nearby structures.

*IONO+ provides advanced protection against ionospheric disturbances.
