Tutorials / Direct

Of the two ways to obtain weather data while operating in a remote environment, email or direct downloads - direct downloads are the easier option.

Imagine this scenario: you are on a sailboat traveling through a tropical paradise and would like to update your weather data. You turn on your satellite device and let it register with the satellite network. In LuckGrib, you easily update the previous GRIB request by adjusting its coverage area to account for where you are now. You then start the download of the data you want by tapping a button. LuckGrib connects to its server cluster using a satellite connection it opens, requests the data it needs, downloads the data provided by the cluster and then disconnects the satellite connection. The entire process only takes several minutes.

Devices supported

The first step when choosing which device to use is to select the direct download option in the LuckGrib application settings download area, and then to choose the device you want. This is a sample of that interface from the Mac product:

The devices that have direct support in LuckGrib are:

Note that if you have a satellite phone, it can be connected to the Optimizer and then used by LuckGrib.

Workflow common to all direct downloads

Regardless of how you are directly downloading your weather data, once the system is configured, they all work very similarly.

When you want to refresh your weather data, the most common workflow will be that you:

At this point, you will be seeing a window similar to this:

Its not uncommon for you to start the download of a file over a slow internet connection only to have an error of some sort occur and for the internet connection to drop out. This is the real world after all and things do not always go perfectly. Satellites may pass beneath the horizon, there may be interference of some kind - this type of drop out should not be unexpected when accessing data remotely.

The faster you can complete your download the better the chances you will not encounter an error. An Offshore Compact file will be roughly half the size of an ordinary file, and so you are half as likely to encounter an error.

If you do encounter a download error, LuckGrib will save all of the data it has received for the GRIB request. When you next reconnect to download the data again, LuckGrib will inform the server that it has a partial download result, along with some information describing it. If the server agrees that the data retained is valid, the server will continue the download from where the error occurred rather than starting all over again.

This ability to restart after an error can save a considerable amount of time, money (if you are paying for data) and your patience - it can be very annoying waiting for old fashioned software to re-download data it already downloaded, over and over again.
