Iridium services : Inflation in Low Earth Orbit

Inflation does not spare satellite telephony 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 (about 2 x 780 km) is directly impacted by the increase in fuel prices ? Damned, I will have to be explained ! 

Still, the bad news has just reached us through our partner : Significant overall increase in Iridium subscription rates as of January 1 2023 affecting all resellers. Read more …

Share GRIB files with Air Share [Update]

Iridium Certus 100, a step towards yachting ?

 Since the operational commissioning of the constellation Iridium NEXT (¹), the Iridium company has started to offer its new range of services called " Certus®".

Iridium GO! A positive feedback [Update]

Iridium GO! cruising

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.

Iridium NEXT maintains its schedule [Update-3]

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.

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.
