Model-inertial deep fusion navigation and impact point uncertainty quantification for rocket sub-stages under prolonged GNSS outages

During atmospheric re-entry of rocket sub-stages, GNSS signals may be lost for extended periods due to plasma sheath and attitude occlusion. In such scenarios, the integrated navigation system degrades to pure inertial navigation, and position errors grow cubically over time, making conventional filtering and predictio...
