N2 - This paper discusses current integrity algorithms to deal with ultra-tight coupled GPS/INS system failures. Using the simulated output of the aircraft based INS and GPS receiver, current integrity algorithms are evaluated. A new algorithm based on detection of the growth rate of a typical test statistic is presented. Results show that the new algorithm detects slowly growing ramp-type failures faster than the current methods. This will enable early detection of such errors for enhanced integrity performance.
