ADS-B transponders on future Iridium NEXT satellites

Posted onOne comment

I mentioned in two previous posts, on the one hand ADS-B equivalent to AIS for aeronautics, on the other hand, the future of satellite communications with the next constellation Iridium NEXT. Believe it or not, the NewScientist teaches us, In a recent article dated 14 December, that the Iridium NEXT satellites will carry ADS-B transmission devices. I give you below a freely adapted translation.

These two communication technologies combined will revolutionize air traffic in the next ten years. 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, who testifies in a very didactic way to his experience during the recent Transquadra, on board "Bluestairs", with the owner and friend Marc Bolla.

—

Placed at the Transquadra 2011/2012, We met, during the first stage of the Mediterranean Barcelona-Porto Santo (Madeira), problems receiving and sending GRIB and data files via the Iridium network. Email was impossible to use with the Iridium Airtime cards we used. All we were left with was the possibility of calling with the Iridium.

Back after this first stage, I decided to deepen the subject and educate myself with Francis Fustier whom I had knowledge, Until now, than through his blog, really comprehensive. Read more …

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 on

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 …
