Improving system resilience to external perturbing factors

The innovative approach proposed here is to combine GNSS data with other avionics measurements in the same integrity processing. Sensor fusion is a promising path to overcoming performance limitations and improving the resilience of individual systems. A combination of GNSS with various types of additional measurements, ranging data (LIDAR, Vision-aided, TAWS) or non-ranging data (IMU) could improve in-flight awareness of airplane position and trajectory or could be used to mitigate continuity events, making for less stringent requirements for the design of individual systems.
