PATHFINDER GNSS is NAVENTIK‘s unique Software Defined GNSS sensor (SDR) that fully substitutes your existing hardware receiver by a flexible and scalable ECU embedded software. PATHFINDER GNSS provides highly accurate multi-band and multi-frequency raw measurements including integrity data. Real-time confidence estimation of GNSS input data is the key to seamless and safety-compliant deep-coupled sensor fusion. With the software approach, our sensor is highly portable and always up-to-date.
PATHFINDER FUSION is NAVENTIK's carrier phase based positioning engine with advanced error modeling and rapid convergence times. It exploits the synergies of GNSS measurements and data from additional vehicle sensors. Starting from inertial system (INS) integration, we provide algorithms that combine odometry or vision-based motion data with measurements from any GNSS receiver, taking into account the vehicle model. In doing so, we also take advantage of modern GNSS augmentation services, which enable a safe positioning with rapid convergence time. PATHFINDER FUSION creates the most robust and accurate navigation solution using all available information.
The joint use of PATHFINDER GNSS & FUSION enables an end-to-end integrity concept, as both the GNSS sensor and the positioning engine are implemented as software without having a "black box" within the system architecture. Integration with additional sensor and SSR correction services is seamless and cost-effective. Furthermore, both modules together interact with each other in deeply coupled sensor fusion mode for extremely robust and uninterrupted high-performance GNSS/INS positioning. Unlike conventional tightly- or loosely-coupled GNSS/INS systems, deeply coupled systems not only combine autonomously generated GNSS and INS solutions. Motion data is used to support and stabilise the satellite tracking of the GNSS receiver in difficult environments or after a loss of the satellite signal. In addition, GNSS measurements from as few as two satellites can be used to compensate for the sensor drift of the intertial unit.
