SBAS for Aviation

SBAS, or Satellite-Based Augmentation System, enhances the accuracy, integrity, and reliability of GPS signals for aviation. It uses ground-based reference stations to monitor satellite signals, then sends correction data to satellites, which broadcast improved positioning information to aircraft. This system helps pilots navigate safely and precisely during all phases of flight, including approach and landing, even in challenging conditions. Think of SBAS as a GPS “upgrade” that ensures pilots can trust their navigation data, ultimately improving safety and efficiency in air travel.
