You are more likely to have adopted the Iridium GO! for its easy way to request GRIB files, directly from Weather4D and some other applications. But some also want to transfer these files to PC to import them into Windows software (as you know, nobody is perfect !). An easy solution is available : the messaging app Air Share, compatible iOS/iPadOS (¹). [Update 30 March 2022] Warning : the app has changed its ID code on the AppStore. Read more …
Since the operational commissioning of the constellation Iridium NEXT (¹), the Iridium company has started to offer its new range of services called " Certus®". These services are based on the considerably increased technological capabilities of the new satellites., which allowed, among others, Iridium to be approved as a second satellite communications provider for the GMDSS maritime security service (²), whose competitor Inmarsat had held a monopoly for 1979.
Certus®, in addition to demonstrating that American businessmen are also literate. (³), is a range available in six bandwith levels starting from 22 Kb/s up to 704 Kb/s, and up to 1408 Kb/s in the near future.
In coastal navigation, so often within range of a cellular network, we can download GRIB files, weather maps, or simply communicate with friends. But what if our smartphone or tablet is already connected via Wi-Fi to a multiplexer?, or an NMEA gateway, without cutting the data that feeds our favorite navigation application ?
This is the summer trick…
[Update 25/09/2020] The trick in question depends on the iOS version used. Details in the article.
The app Iridium GO!®, used on our smartphones (iOS/Android) to connect to the Iridium network using the same name device, just undergone an happy facelift. Nothing really fundamental, if only the user interface, but a stylish graphics help for first-time users. Read more …
Since it was introduced to the market in September 2014 (Eh, yes, 5 years ago !) this device, with its indisputable ergonomics and excellent quality/price ratio, has become a must-have for offshore sailors. Easy to implement, without the need for an external antenna (except metal build) it can be used inside the boat.
A test run of several weeks, conducted in October and November 2016 during a transatlantic delivery, had already demonstrated its ability to download GRIB weather files and weather maps despite the low rate (about 10 KB / mn). With the new Iridium NEXT constellation (¹) we notice since 2019 a real improvement in the global coverage without satellite disconnection.
June 2012, I wrote a post about the future constellation of communications satellites Iridium NEXT. While intended for operational use in 2017, the calendar was shifted a few months. Indeed, the launch of the first ten satellites by the private company SpaceX, originally planned on 12 September 2016, was postponed for a few months by the explosion on September 1, a Falcon rocket 9 rocket explosion during the fuel filling on its launch pad before a shot of engine test.
[Update 15 February 2019] The recent update of the application Iridium Mail & Web gives me the opportunity to refresh the ticket originally written in December 2011.
The Wi - Fi gateway Optimizer RedPort the company enables owners of a mobile satellite phone to query and receive GRIB weather files from an iPad or iPhone on the high seas, into the wild, anywhere on the world.
Having implemented and tested this solution on a long journey, it has proven perfectly operational. However, it is limited to receiving only predictions GFS weather model global, and model WW3 waves, obtained by the autoresponder US server Saildocs.
