The relationship of a recent experience of an iNavX user and Weather4D PRO routing function invites me to bring a warning to the attention of novices boaters in computer use.

A regatta course, départ de St Hélier (Jersey) to arrival Granville, optimized with Weather4D PRO using fine grid GCWF model and MyOcean currents prediction, donnait la route suivante dans iNavX :

ADS-B transponders on future Iridium NEXT satellites

Posted on17 December 201215 August 2024One comment

I mentioned in two previous posts, d’une part le système ADS-B équivalent de l’AIS pour l’aéronautique, d’autre part le futur des communications satellites avec la prochaine constellation Iridium NEXT. Figurez-vous que le site NewScientist nous apprend, dans un récent article daté du 14 December, que les satellites Iridium NEXT vont embarquer des appareils de transmission ADS-B. Je vous en livre ci-après une traduction librement adaptée.

Ces deux technologies de communication associées vont révolutionner le trafic aérien dans les dix ans à venir. Read more …

When AIS becomes Virtual Aid to Navigation

Posted on3 th 20124 th 2024

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 on5 th 20124 th 20242 comments

After 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 …

Galileo, here we go !

Barely published, the 20 October, my previous post about iPhone 4S new GPS chipset – allowing you to receive signals from the Russian GLONASS system – in which I inserted a skeptical comment about the future of Galileo, that I see myself caught up in the news.

Not only did the first two satellites of Galileo were launched the next day 21 October with success from Kourou, but also by the Russian Soyuz launcher ! I hope you enjoy the comic of the situation… Read more …

When Katia meets La Louise

Posted on11 th 20113 th 2024

Thierry Dubois and his teammates, dont Jacques Vermeulen experimenting its Iridium connection with its new MacBook Air, must not be laughing at the time I post this short post.

La Louise, conveying from Newfoundland to La Trinité, is being caught up in Hurricane Katia, ex-tropical cyclone, which is due to reach the coast of the British Isles next night. Based on last position and estimated speed, La Louise should be in the west of the weather area "Romeo", either in the southeast of the center of the Low, its intended position on the Navimail map below the location of the red boat at 18h UTC : Read more …
