NAVENTIK‘s unique Software Defined GNSS sensor fully substitutes your existing hardware receiver by a scalable ECU embedded software. PATHFINDER GNSS provides highly accurate multi-band and multi-frequency raw measurements including integrity data. Real-time confidence estimates for GNSS raw measurements are key to implementing functional safety concepts for ADAS positioning. The software approach also enables deeply coupled and seamless fusion with other vehicle sensors. Our software GNSS measurement engine is highly portable and always up to date.
NAVENTIK's embedded positioning engine with advanced error modeling and rapid convergence times leverages the synergy of GNSS measurements from any receiver and inertial and vision-based systems to ensure continuous and robust positioning, even under the most challenging GNSS receiving conditions. The vehicle system model and other system parameters are taken into account to increase the performance even more. PATHFINDER emPE generates a highly accurate position including integrity data for vehicle localisation for safety-critical applications.
The joint use of PATHFINDER GNSS & emPE 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 sensors 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.
Carrier phase based positioning engine with advanced error modeling and rapid convergence times, interference mitigation and monitoring.
Adding inertial or vision aided navigation increases availability and continuity of the solution, seamless integrated on vehicle ECU.
PATHFINDER eliminates hardware limitations by a software approach to a minimum (RF stage + antenna).
Development according to automotive safety standards (ISO26262) to meet Automotive Safety Integrity Levels (ASIL).
PATHFINDER ensures maximum flexibility in component selection by supporting any suitable GNSS and IMU sensor and SSR correction service.
PATHFINDER is written in C++ and can be ported to common automotive processors and operating systems.
