Abstract
A method for multi-track environmental fault monitoring for aerial platforms includes estimating a normalized squared residual error (NSRE) for each of one or more satellite-receiver tracks over time. The method also includes determining an averaged NSRE for each satellite-receiver track by averaging the NSRE over multiple time windows. The method further includes performing a threshold test on the averaged NSRE to determine a filter state. In addition, the method includes determining whether to apply a scale factor for each satellite-receiver track based on the filter state.
