Satellite-based Augmentation Systems (SBAS)

Satellite-Based Augmentation Systems (SBAS) enhance the accuracy and reliability of global navigation satellite systems like GPS. They do this by using ground stations to monitor satellite signals, correcting any errors or discrepancies, and then transmitting these corrections back to users via additional satellite signals. This ensures that navigation information is more precise, which is especially important for aviation, maritime, and engineering applications. Essentially, SBAS acts as an advanced GPS upgrade, providing safer, more reliable positioning data over large areas by integrating satellite and ground-based technology.
