Space Based Augmentation Systems (SBAS) have been developed principally to augment the Global Positioning System (GPS) for aviation and other safety of life applications.
The original protection level equations for SBAS assumed that all actual error distributions could be easily overbounded by zero-mean gaussian distributions. However, several error sources have since ...
