Reducing the risks posed by space weather with celestial navigation

Date: June 8, 2016

Steve Bell, Head of HM Nautical Almanac Office at the United Kingdom Hydrographic Office (UKHO), discusses the need for celestial navigation skills and the risks posed to mariners by space weather.

During the many long voyages ships carry out each year, crews have become increasingly reliant on electronic positioning systems to help them fix their location and have subsequently reduced their use of celestial navigation on board. In fact, in a recent survey conducted by UKHO, only 35% of mariners surveyed said they actively practice celestial navigation on board each week. Without these key skills crews are becoming subject to increased risk at sea, particularly from the potential failure of GNSS systems and various types of high frequency radio communications.
