  "textContent": "The system (1) has an inertial navigation center (3) for providing aircraft positional information partially from accelerometric and gyrometric measurements, and a satellite positioning module (5) to determine another aircraft positional information from satellite positioning data received by a satellite navigation data receiver. An estimation unit formed by the center and a localization module (9) estimates a localization of aircraft at estimation time based on the information. The localization is determined independently from the data received in a preset time interval preceding the time. The aircraft positional information is a Global Positioning System (GPS) data. The time interval is equal to a time to alert. An independent claim is also included for a method of navigation assistance of aircraft.",
