1. A method comprising:

  • receiving data from a plurality of receivers on a platform, wherein the data corresponds to one or more satellite-receiver tracks, each of the one or more satellite-receiver tracks having an error bound;

    generating an attitude correction for the platform based on the received data;

    determining a convergence test statistic of the attitude correction;

    determining a convergence level of the attitude correction using the convergence test statistic; and

    responsive to the determination, monitoring a carrier phase error of signals received from the one or more satellite-receiver tracks, wherein monitoring the carrier phase error comprises;

    determining excluded satellite-receiver tracks having a carrier phase error greater than or equal to a carrier phase error threshold;

    monitoring the satellite-receiver tracks based on convergence level of the excluded satellite-receiver tracks and using the error bounds of the excluded satellite-receiver tracks when generating the attitude correction.
