NMEA OneNet® : a new high-end communication standard

Posted on24 January 202425 January 20243 comments

20 years after NMEA 2000 and more than 40 years after NMEA0183, OneNet® is the third generation NMEA standard for marine data interfacing and networking.

In development since 2010 by NMEA members (¹), to be published in late 2021, the OneNet standard is based on the IP Internet Protocol (²) version 6 (IPv6) and works on the IEEE Ethernet local network 802.3. This new standard aims to combine the three NMEA data standards — OneNet, NMEA 2000, NMEA0183 — on a single local network (LAN). Read more …

R-Mode, future alternative to Positioning System

Posted on11 December 20237 th 2024

Global navigation satellite systems GNSS (Global Navigation Satellite System), have become the primary source of Positioning, Navigation and Timing (PNT¹) for ships and marine operations. GNSS is also used for the automatic identification system (AIS²). Unfortunately, GNSS is recognized to be vulnerable to jamming and spoofing, intentional or not, that may result in the loss of positioning information, or, still worse, inaccurate positioning information.

Weather4D and iOS LAN

Posted on18 June 20213 th 2021One comment

From iOS/iPadOS 14.5, A new setting has appeared proposing to allow applications to access the Local area network. This option is offered when installing a new application, but is not necessarily activated if the application is already installed when the OS is updated.

Since then, Many of you are no longer able to connect certain applications (Weather4D, iNavX, aso.) Wi-Fi-connected devices : Iridium GO!®, Multiplexers, Miscellaneous NMEA gateways. To do this, you must activate this "Local network" option for the application concerned. Read more …

Iridium GO! cruising

Since it was introduced to the market in September 2014 (Eh, yes, 5 years already !) 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, carried out 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 (environ 10 KB / mn). With the new Iridium NEXT constellation (¹) we notice since 2019 a real improvement in the global coverage without satellite disconnection.

Weather4D and SailGrib improve the AIS network

Posted on5 June 201921 January 20227 comments

Numerous AIS tracking networks broadcast over the internet are available. Among the best known : Marine Traffic, Vessel Finder, SiiTech, LocateEverything, and many others. One of these networks particularly stands out, AISHub, an AIS NMEA data sharing center, which offers developers an API allowing the integration of its network into applications, and therefore display of AIS targets received over the Internet directly into the application. Featured from the beginning in Weather4D Routing & Navigation, this system has made it possible to envisage new and particularly innovative services. Read more …

Signal K Project, universal open source marine data sharing

Posted on29 October 20156 th 20242 comments

You will soon hear about Signal K, a marine data communication standard, developed in open source, which aims to replace NMEA standards (0183 and 2000) technically overwhelmed by the exponential development of connected objects. The designers intend to provide an open and free protocol to developers and manufacturers alike., allowing to get over the constraints linked to the NMEA : license costs, flow limits, limit the number and type of devices, unsuitability for complex environments, to wireless communications, therefore incompatible with the Internet of Things and the Internet itself.

Iridium unifies the use of its mobile devices

Posted on29 th 201419 July 20204 comments

Since the release of Iridium GO! (¹) There were two different pages of subscription (for free) to messaging service, and two applications (iOS/Android) to connect to Iridium devices. Now there is only one application : Iridium Mail & Web app pour se connecter soit au routeur Optimizer, soit à Iridium GO! Read more …

Iridium GO! keeps its promises [Update]

Posted on17 th 201416 th 20242 comments

Since its announcement last February, and GO! took a long time to arrive at retailers until the beginning of this month. The company E-SAT gave me one to conduct some tests. Although too late to carry out these tests at sea, the Quai des Antilles on the Ile de Nantes offers a wide sky clearance also than the deck of a boat, enough to connect satellites of all-round. Two types of tests were carried out : requests and receipts of GRIB weather files from an iPad featured with Weather4D PRO app, functions related to telephony from an iPhone.

With IsatHub, Inmarsat promises to connect - much - faster [Update]

Posted on21 June 20145 th 20242 comments

After the announcement with great pump of the GO! by Iridium few month ago, but not yet available, Inmarsat has introduced IsatHub at CommunicAsia show which just closed its doors in Singapur. The competition is tough between the two industrial, but unlike Iridium more oriented towards mainstream users, Inmarsat is aimed primarily at a professional market.

IsatHub is a WiFi hotspot allowing to connect all mobile devices to Inmarsat satellite network. No need cellular towers, IsatHub provides aworldwide connectivity to your tablets and smartphones.

Global satellite company aims at the consumer market with Iridium GO!™ : pack it for camping or world travel.

In all public places where you can wirelessly connect to the Internet today, une connexion Wi-Fi n’est pas encore omniprésente. Et si vous êtes un plaisancier, randonneur, pilote, en camping-car ou quelqu’un qui passe beaucoup de temps dans la nature, les chances de vous connecter au cyber-espace dans certains endroits éloignés est presque impossible. Il ne s’agit pas seulement des données. Try making a cellular phone call in such places !
