Workshop - Diving into ROSaic: GNSS driver for ROS

Free 60-minute webinar/technical workshop-on-demand

Empower your robotic navigation or mapping functionality with centimeter-level RTK positioning and orientation. Find out how the ROSaic C++ driver makes it easy to integrate the mosaic GPS/GNSS module and other Septentrio multi-frequency receivers into any technology based on the Robotic Operating System (ROS).

Take a look under the hood with the authors of ROSaic and the maintainers of ROS to discover:

  • What is ROSaic and what is the best way of using it
  • ROS messages/topics inside the ROSaic package
  • The optimal way of integrating the latest GPS positioning tech
  • How to integrate a dual-antenna GNSS or a GNSS/INS system for heading, pitch, roll angles
  • How are GNSS high-accuracy corrections handles in ROS
  • Other ROS drivers for high-accuracy positioning

The ROSaic has been designed for quick integration of GNSS positioning. This ROS package publishes NavSatFix, GPSFix and PoseWithCovarianceStamped messages. It also allows subscription to a set of common NMEA sentences - conforming to the NMEA standard as well as to a range of proprietary Septentrio Binary Format (SBF) messages. User-specific ROSaic parameters allow the configuration of differential correction services via NTRIP for a variety of hardware setups. Find out all about these messages and more during this technical workshop.
