Internet par satellites : Riffifi in the firmament

Posted on27 February 202310 June 20242 comments

In space, in an area called LEO (Low Earth Orbit) located at a distance of approximately 200 up to 1.000 km above our heads, several hundred, even thousands, satellites are already flying. They are mainly dedicated to communications and observations of all kinds, civil and military.

But for a short decade a fratricidal war has been declared, a frantic race between several private and semi-public companies to offer high-speed internet to all humans, wherever they live on the globe. The thing is important, because this market, beyond the altruism and generosity displayed by these ambitious programs, promises several billion dollars in earnings in the coming years. Read more …

Iridium services : Inflation in Low Earth Orbit

Posted on12 November 202212 November 2022One comment

Inflation does not spare satellite telephone services, to believe that the price of radio waves increases with the cost of transport ! Does this mean that the cost of the round trip of a radio wave toward Iridium satellites (environ 2 x 780 km) is directly impacted by the increase in fuel prices ? Damned, I will have to be explained !

Anyway, the bad news has just reached us through our partner iTabNav.fr : Significant general increase in Iridium subscription prices on January 1 2023 affecting all resellers. Read more …

Urgent ! Iridium GO!® firmware update and app GO!®

Posted on5 October 202110 October 20214 comments

A new version of the firmware 2.1.22 is now available for the’Iridium GO!®. This release includes an update to fix an incorrect time and date issue for the device Iridium GO!® and the application GO!®. This problem does not affect the functionality of the device/application. Appeals, the data, SMS, SOS and follow-up are still working normally. Only cases where a message (Quick GPS, tracking, SOS) contains a date/time, this one will be incorrect. The order of messages in the Iridium GO app!® may not be respected, as well as missed voice calls. Upgrading the device to the new firmware version 2.1.22 will fix this issue.

Simultaneous Wi-Fi and cellular connection [Update]

Posted on25 th 202017 February 20227 comments

In coastal navigation, so often within range of a cellular network, you can download GRIB files, weather maps, or simply communicate with friends. But what if your smartphone or tablet is already connected to a multiplexer via Wi-Fi, or an NMEA gateway, without cutting off the data that powers our favorite navigation app ?

This is the tip of the summer…

[Update 25/09/2020] The trick in question depends on the iOS version used. Details in the article.

Iridium GO! cruising

Since it was introduced to the market in September 2014 (Eh, yes, 5 years already !) 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, carried out 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 (environ 10 KB / mn). With the new Iridium NEXT constellation (¹) we notice since 2019 a real improvement in the global coverage without satellite disconnection.

The new Iridium NEXT constellation is completed

Posted on11 January 20196 th 2024

A few months late, Iridium has just completed its Iridium NEXT satellite launch campaign (¹).

With his 75 new satellites successfully deployed by SpaceX over the past two years, Iridium has achieved the feat of completely replacing its first constellation in record time. The last ten satellites, successfully orbited this January, 11 with a Falcon rocket 9 during the eighth and last launch, definitively complete the new constellation.

Iridium NEXT maintains its schedule [Update-3]

In June 2012, I wrote a post about the future constellation of communications satellites Iridium NEXT. While intended for operational use in 2017, the calendar had been shifted by a few months. Indeed, the launch of the first ten satellites by the private company SpaceX, originally planned on 12 th 2016, was postponed for a few months by the explosion on September 1 of a Falcon rocket 9 rocket explosion during the fuel filling on its launch pad before a shot of engine test.
