How do you get Theyr GRIB service via iridium Go!

Welcome to the Raymarine Forum Ryearsley,

As long as the Iridium go can provide a good Internet connection that allows the ports below to be open, in theory it should work fine, although expensive and slow.

The issue arises when local network administrators forbid outgoing connections for unknown applications or when local web proxy only allows a very strict subset of http traffic/commands.

In order connections and downloads would be possible, the following should be allowed:

1. Connection to forecast.theyr.com:80 (82.163.72.57 port 80)
2. Connection to kona1server.theyr.com:30080 (82.163.72.56 port 30080)

So one would need to unlock these ports for it to work, the MFDs also ping 8.8.8.8 to check we have a valid internet connection ... this is a Google public DNS.

1-2 Kbps would also be very very slow and very costly, I would think, a file we have just downloaded in the office as a test is 23MB (23000Kb) and at that speed would take 3.19 hours at 2Kbps and 6.39 hours at 1 Kbps. The reviews posted on Amazon for the Iridium Go are not impressive, frequently dropping connections, expensive data plans, and very restricted Internet to only mobile sites only.

Based on this the reviews and this articles, this method of accessing Theyr weather would not be recommended. Sorry to be negative, just don’t want to give false hope.
