First question - do you have a marine antenna
for your Iridium phone
? Data connections require a stronger and more consistent signal, so without a marine antenna
, the phone
will often drop the data connections – especially if the boat is moving about a lot.
Make sure your computer has everything disabled that could use data in the background – such as Windows updates, antivirus updates, itunes etc. If something is trying to pull in an update without you knowing, it will make grib downloads impossible (don’t forget to re-enable them when you get back on a normal internet
Rather than using email to receive your grib files, I would recommend some free software
called Ugrib. This collects the files directly from the Ugrib server, so is quicker and more bandwidth efficient than pulling the grib files from your email software. It also compresses the grib files so that it keeps file transfers as small as possible. This means that you don’t need any additional compression
Make sure you get gribs for as small an area as possible and keep the number of days' data that you require to a minimum – this will keep the file size down.
You can install Ugrib and familiarize yourself with it using your normal internet connection.
You can get ugrib here www.grib.us
I hope that helps! I'd be interested to know how you get on.
