[Update 31 July 2021]

Developed for over a year jointly by Henri Laurent (SailGrib) and Olivier Bouyssou (Weather4D) this new interface already allows the recording of all navigation data, either cellular connection (real and / or deferred time), either satellite connection with Iridium GO!® (according to the configured frequency), either by the MMSI number via the AISHub network (²). Tracks, data from connected instruments, and, icing on the cake : the recording of the data entered in alogbook !

Plusieurs étapes groupées dans le trajet Aller

Several trips grouped together in the outbound journey


In Navygatio website we create an account, exclusively with a Google email address (Gmail) or Apple (Apple Store account address). We enter the information about the boat, then we create an activity. It can be a cruising voyage, a training, a regatta, etc,.

We can create as many activities as we have navigations, cruises or regattas, to perform. In the same activity, several trips can be recorded if necessary. We can then group the trips together in a single journey to replay it on the screen.

Once the account has been created on the website Navygatio, we connect to it in Weather4D Routing & Navigation via a new entry in the "Navigation" menu.

Connexion avec Weather4D Routage & Navigation

Select the email address used in Navygatio, the name of the boat, and the current activity to choose from a list of activities. When leaving, after activating the navigation mode in Weather4D, just activate "Data transfer". They will be synchronized, either in real time with an internet connection (cellular connection near the coast), either deferred as soon as a connection is available (cellular or satellite).

We see the track and the transferred data displayed on the screen, all available data attached to the route is recorded.

By clicking on a data label in Navygatio, a graph traces its evolution over time. We can move forward or back in time, you can also click anywhere on the track line to bring the boat back to it and read the data at that point in time, for example when tacking. You can also display average values ​​over time.

At the end of a course, just turn off data transfer to stop recording. Like this, several successive tracks can be recorded for the same cruise, or several stages of the same regatta, by reactivating the transfer at each new start.
