Abstract
A method for real time subset geometry screening comprises the steps of determining a list of satellites in view of a ground based augmentation system in a navigation satellite system for a subsequent time interval in the future, defining at least one set of subset geometries from the list of available satellites, calculating a respective first σfor each of the at least one set of subset geometries, setting a respective broadcast σfor each set of subset geometries as the larger of the first σand a second σ, wherein the second σwas calculated for the previous time interval, saving the first σfor a next iteration of the method, and selecting from the plurality of broadcast σto match an available broadcast constellation. σis a vertical ionosphere gradient standard deviation.
