Satellite-based augmentation systems

Satellite-based augmentation systems (SBAS) improve the accuracy and reliability of GPS signals by using additional satellites and ground stations to monitor, correct, and transmit precise positioning data. They enhance GPS performance for critical applications like aviation, surveying, and navigation, ensuring users receive more precise location information. Essentially, SBAS acts as a quality control system that detects and corrects errors in satellite signals, providing users with higher accuracy and confidence in their position data.
