BBC Radio 4 – The Shipping Forecast celebrates its 100 years old

Posted on4 comments

2025 marks the 100 years of the broadcast of marine weather forecasts The Shipping Forecast on BBC Radio 4. This emblematic transmission, produced by the UK Met Office on behalf of MCA_media, continues to be a vital safety service for mariners along our coasts.

I had written an article at the beginning 2010 (¹) on the gradual disappearance of radio weather forecasts in France, and praised the consistency of the BBC bulletin. Fifteen years later, the marine weather forecast is still broadcast on BBC Radio 4 Long Waves at the same unchanging times. Hats off ! Read more …

Starlink Mini : a stone into the sea [Update-2]

Posted on18 comments

Since the launch of Starlink in 2020, the hardware and service offerings were particularly versatile (¹). If the first recreational boaters were able to benefit from a navigation service far superior to the official conditions of use, it seemed obvious that this somewhat chaotic launch period would eventually be regularized, and offers stabilized. Despite still a strong disparity in equipment and subscription pricing from one continent to another, or even from one country to another, we are starting to see more clearly.

This is the case for France with the arrival of Starlink Mini. [Update of 11-12 th 2024] Read more …

Starlink goes from strength to strength but still offers versatile services

Posted on2 comments

Since the first launch in 2018 more than 6.600 satellites Starlink have been launched to date, of which almost 6.100 are operational (¹). Satellites have evolved technically, just as the infrastructure was gradually improved. They are launched in packets of 20 to 23 at the rate of one SpaceX flight on average every ten days. However, the planned constellation of 34.396 satellites is still far from being achieved. Service coverage expands over time with the addition of new territories as requests for authorization from States are successfully completed. (²).

For more than four years, many boaters around the world have equipped their boat with an antenna/router kit by using the “Roaming” service. (ROAM in English) Who, with a particularly low cost, offers the possibility of maritime use off the coast thanks to an activated “Mobile Priority” option.

But everything is not as simple as that… Read more …

Posted on4 comments

Since the operational commissioning of the constellation Iridium NEXT (¹), Iridium has begun offering its new range of services called " Certus® ”. These services rely on the significantly increased technological capabilities of new satellites, which has made it possible, among others, Iridium to be approved as a second satellite communications provider for the GMDSS maritime security service (²), of which the competitor Inmarsat has held the monopoly since 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.

Internet par satellites : Riffifi in the firmament

Posted on2 comments

In space, in an area called LEO (Low Earth Orbit) located at a distance of approximately 200 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 onOne 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 …
