In this chapter I’m going to get into the details of how we request and use GRIBs to get the maximum amount of information for the minimum data size and cost, when at sea or in remote areas with no internet.
Update November 2017
We now use an Iridium GO! with unlimited data for all weather product downloads including weatherfax so most of what we do, and recommend, has changed from this post. We have written about our new system in detail starting with this chapter.
That said the system we detailed in this chapter will still be of use to those who decide to stick with an Iridium handset without unlimited data, or an SSB radio with PACTOR modem.
