How does the aircraft ensure navigation accuracy during satellite failure?

Selecting alternate navigation sources is crucial for maintaining navigation accuracy during satellite failure. The aircraft is equipped with various navigation systems such as inertial navigation systems (INS), ground-based navigation aids like VOR (VHF Omnidirectional Range) and NDB (Non-Directional Beacon), and RNAV (Area Navigation) systems. These alternate sources can provide positional information and guidance even when Global Navigation Satellite Systems (GNSS) are unavailable due to malfunction or interference.

Relying solely on visual flight rules would not suffice in many instances, especially in situations requiring instrument navigation, as it requires clear visual references that might not be available in all weather conditions. Similarly, increasing autopilot settings or adjusting flight speed do not address the need for accurate positional data and may not assist in finding alternate navigation solutions. Thus, having access to alternate navigation sources ensures that the aircraft can continue to operate safely and effectively, maintaining accuracy even during satellite disruptions.
