Multi functional electronic wrists watch to support navigation, notably for a space mission. Electronic watch for spatial mission has push buttons and logic circuit to generate mission elapsed time scale found from Greenwich meridian time scale, and digital display unit to display negative and positive time values based on date. Can be used by an astronaut for a spatial mission of long duration.
In the conventional world-time displayable electronic timepieces, comparison between an specific reference time that can be associated to a universal time as GMT or to an internal reference, as the start of an specific event cannot be displayed. As a result, this invention gives an advantage over other technologies and products.
An ad-hoc assessment will be done for each specific application
Applicable to any activity lasting several days or hours that the start time is precisely dated events and whose characteristics require a reference time, internal, that is to say, relative to the start of the mission or externally, as universal time. These activities can occur in air, underwater, sea, mountain expeditions and caving. They can be associated with exploratory or record attempts.
Applications: Aerial flight, terrestrial and marine displacements and speleological mission.
