On April 6, five Coastal and Marine Automated Systems (C-MAN) stations in Cook Inlet failed after running out of date storage in their GPS systems due to a GPS Rollover.  Through a collaborative Alaska NOAA effort, one station has already been repaired and a schedule for repairing the others is in place.

A list of impacted Alaska C-MAN stations is as follows:

  • Augustine Island (AUGA2)- repairs completed on 4/9/2019
  • Flat Island Light (FILA2)- around April 20 weather and marine mammal permitting
  • East Amatuli (AMAA2) – week of April 22
  • Pilot Rock (PILA2) – Week of April 22
  • Drift River Terminal (DRFA2)- To be determined
