However, one very interesting new issue was brought to our attention. We were informed that other GPS block IIR and IIR-M satellites may show similar problems as SVN-49 because they use a similar configuration as SVN-49 but of course for a different signal then the L5 signal. So we took a close look at the residuals of all the GPS and GLONASS satellites and discovered that several other GPS block IIR and IIR-M satellites suffer from a similar, albeit much smaller, signal anomaly as observed for SVN-49. Most pronounced anomalies are observed for SVN-55 and SVN-43.
