The deeply-coupled combined navigation algorithm lifts the quality of GNSS signal observation. Aided by IMU, deeply-coupled algorithm will increase the positioning accuracy by twice to 5 times than loosely-coupled algorithm.
Bynav REAL GNSS positioning engine has integrity monitoring and partial ambiguity solution algorithm to improve the fault tolerance and fixed solution rate under multipath and interference conditions in urban environments. High-quantity signal preprocessing and interference suppression are adopted to greatly improve the availability and integrity of high-precision positioning in vehicle scenarios.
The system is modeled based on the characteristics of vehicles and optimized for specific scene applications. It effectively handles complex scenarios such as underground parking lots, tunnels, viaduct, city streets and ports, addresses issues like obstruction and highway signal interference.
