Weather4D Routing & Navigation

Weather4D Routing & Navigation is a satellite maritime app for the Iridium GO!® that integrates weather forecasting, routing calculations, navigation with digitized raster charts, instruments and data sharing to maximize your boating experience.

Weather4D includes two other flavors which support Iridium Go! direct download:

A fourth application called iWatchSat indicates when a satellite is easily reachable with Iridium.  With an improved connection and signal quality, connection attempts and time to download are considerably reduced.
