Iridium NEXT the future

Posted on

Constellation Iridium actuelleThe use of Iridium is taking a growing place among offshore sailors. The security of being able to join your family at sea at any time, or to be able to contact a medical service in the event of an emergency, are arguments often raised by buyers. In addition, The satellite phone offers data services to send and receive SMS and emails, and above all make GRIB weather file requests. Unfortunately, To date, the bandwidth offered for data exchanges is extremely low, not authorizing more than 2400 bits per second on average for use from a mobile phone. Only large fixed installations, out of reach of the average boater, offer speeds up to 128 Kbps.

And tomorrow ? Iridium Communications Inc., based in McLean, Virginia (USA), announced in June 2010, the launch of a major programme to develop a constellation of next-generation satellites, gradually replacing the current one : Iridium NEXT. Read more …

IsatPhone Pro versus Iridium, which one to choose ?

Posted on4 comments

I just read, dans le dernier numéro de Voiles et Voiliers daté de mai 2012, un comparatif Inmarsat-Iridium qui me laisse insatisfait. Quite interesting in form, it presents a lot of approximations in substance, et ne permet pas au lecteur de se faire une opinion sur des éléments de comparaison précis et chiffrés. On the other hand, n’en déplaise à François-Xavier Ricardou, les solutions logicielles pour Mac existent depuis longtemps et sont parfaitement éprouvées : just to see the number of participants provided with Mac or iPad at ARC 2011. I will try to contribute complementary, je l’espère, éclairera les acheteurs potentiels. Read more …

When AIS becomes Virtual Aid to Navigation

Posted on

The acronym " VAtoN " means in English Virtual Aid to Navigation. In French : Virtual assistance to navigation (¹).

This concept is an extension of the AIS system. It allows, by means of a spacific AIS transponder located onshore, managed by an administration software, reporting virtually unreported hazard. The position of these hazards is plotted by an AIS target as an appropriate icon. For example, a buoy indicating a flush rock may have been temporarily destroyed by a storm. The VAtoN compensates for the absence of this mark while the maritime services put it back in place. Another example, creating an exclusion area of prohibited anchorage has not yet been an update on ENC charts. Read more …

Testimony : Transquadra and Navigation Mac

Posted on2 comments

BluestairsAfter Jean Debèze, avid supporter of Navigation Mac, made me the pleasure of a detailed tutorial about installing a multiplexer aboard his sailboat, here's a ticket by Jacques Vermeulen, qui témoigne de façon très didactique de son expérience pendant la récente Transquadra, à bord de « Bluestairs », with the owner and friend Marc Bolla.

—

Placed at the Transquadra 2011/2012, nous avons rencontré, lors de la première étape de Méditerranée Barcelone-Porto Santo (Madeira), des problèmes de réception et d’envoi de fichiers GRIB et data via le réseau Iridium. Email was impossible to use with the Iridium Airtime cards we used. Ne nous est restée que la possibilité de téléphoner avec l’Iridium.

Back after this first stage, I decided to deepen the subject and educate myself with Francis Fustier whom I had knowledge, jusqu’alors, que par son blog, really comprehensive. Read more …

Simple and original mount for iPad

Posted on3 comments

Serge Rousseau, A Canadian navigator, sent me some pictures of the installation of his iPad on his sailboat. He wrote me :

"I'm sending you some photos of the support. I fixed an industrial Velcro on the stainless steel tube and I maintain waterproof case (+or- 50 €) with reusable fasteners (Tie Wrap). You can also use a waterproof envelope used to protect the maps in kayaks and secure it with velcro and reustable ties. ”

For a particularly economical solution, I find it simple, clever and aesthetic enough for my own opinion. It's up to you to judge…
