EASA: Operators Need To Prep for GPS Rollover Event

On April 6, navigation data from some GPS receivers will become inaccurate unless they are reset to account for the next so-called “week number” rollover event, according to a new EASA Safety Information Bulletin. If affected GPS receivers are not reset by that date, the time data used for navigation solutions will be inaccurate. “A nanosecond error in GPS time can equate to one foot of position error,” EASA said.
