Iridium 9555 and 9575 (Extreme) phones and Windows 10 Driver Problem

Important note to users of Iridium 9555 and 9575 handsets:
We are getting reports of Iridium USB driver incompatibility with Windows 10 systems.

We have confirmed that a PC upgraded to Windows 10 will not work with an USB connected Iridium handset. Open the port to connect to the phone results in an instant BSOD crash.

We have not confirmed if this also happens with PCs originally shipped with Windows 10. If you have more information, please let us know.

Iridium is aware of the problem and is working on a solution. They have not, however, given a date when a fix or updated driver will be available.

How to request PredictWind data via email/SailMail

How to download with a Satellite/SSB Connection using an email request

NOTE: This help topic is not relevant for Iridium GO! users.

• Open the PredictWind Offshore App

• Move your start point (green) and your destination point (red) to your desired locations. You can zoom in and out to get a better view of your route. Please ensure your start and destination points are in the water and not on land. Each time you change your route the App automatically selects the relevant high resolution & offshore GRIB files, GMDSS text forecasts & Satellite imagery.

• You can add intermediate waypoints (between start and destination) by clicking on the “+” button next to the start waypoint control – top right of the screen. For the purposes of weather routing, we recommend that you minimise the number of waypoints so the weather routing is free to find the optimum route.

• Click ‘Download’ button from the left menu

• Make your selection of items to download. The total file size to receive via email is shown above the download button.

• Click ‘Next’.

• Choose ‘Email’ tab.

• Make your final selection of items to download. The total file size to receive via email is displayed below the table.

• Click ‘Save Request’ – save the file to your ‘desktop’.

• Open a new email. Send the saved file to by attaching the file to the email. You can leave the subject line blank. Please Note: The email will be sent back to the email address that you send the request from.  You do NOT need to change the email address for your PredictWind login.  

• After a few minutes you will receive multiple emails with GRIB files and PWU files.  Save these files to your ‘desktop’.

• Go back to the PredictWind Offshore App.

• Click File > Open. Please use the ‘ctrl’ button to select multiple GRIB files, and the PWU file.

• The PredictWind Offshore App will then load the files into the app. You can then view the files that you have downloaded by clicking on the different Menus and Views

NOTE: For SSB radio services there are maximum file sizes that these services allow. Please make sure your requests are below these limits.
