Timing Anomaly in GPS Ground System

If you were working with legacy GPS systems during the time period from 12:49 a.m. to 6:10 a.m. Mountain Standard Time on January 26 of this year, the position data you collected may contain large errors. The U.S. Air Force announced that this problem was caused by the failure and removal of the space vehicle SVN 23, which resulted in a GPS ground software issue and caused a timing error of 13 microseconds on legacy L-band signals. This spike in timing error could have resulted in positional errors up to 4 kilometers.
