GNSS backup position:
In the previous implementation a position had to be provided by the module in order to be stored in the log. This may cause a wrong position entry (default) in the log, for example if signal is lost while preparing for the dive in the water. To avoid this the last received position will be used for ~2 hours => Diver may take the dive side position before starting with the dive preparation. The last known position will be display in the GNSS position search window as well.
