APP4NAV discontinues the Android version of Weather4D

Weather4D had been ported to Android from fall 2013. One year later, in december 2014, Weather4D integrated charting navigation, NMEA data support via TCP-IP, autopilot control. Routing was only missing, already developed on iOS for Apple devices.

Alas, the following years, the time-growth of iOS development did not allow the developer to follow the Android version in parallel to the same level of functionality. Finally, two years ago, Google announced that applications using native code should include a version 64 bits (in addition to the version 32 bits). Read more →

Heat wave ? How to refrigerate your iPad

My friends Christiane and Jochen Lührs are the proud owners of a superb classic ketch German building, Socorro, with which they regularly cross the west European coasts. Fully built of solid wood in 1951, they maintain her with meticulous care, after many navigations from Norway to Scotland, and Europe to the West Indies.

In stopover a few days ago in Vannes, I had the great pleasure to visit them. I knew Jochen when he was the German translator of iNavX, now a fan of Weather4D. I finally got to visit their magnificent boat, which attracted more than a glance along the quay, with its perfect polish, its gleaming stainless steel, its masts Spruce, and impressive wheelhouse. I have also discovered an amazing invention… Read more →

Which iPad for navigation ? [MAY-7]

You are still many to wonder about the choice of an iPad for navigation use. Unfortunately do not have time to respond to every request a post is required. A few years after a first similar entry, must annually re-update the issue, and sometimes more often.

With the presentation of the new iPad Air (iPad Air 3 ?) 2019, this tablet is inserted between the iPad 2017/2018 (low-cost) and the recent iPad Pro 11″. A bargain at a very attractive price for a machine with the A12 Bionic processor .

Weather4D and SailGrib improve the AIS network

Many AIS tracking networks broadcast over the Internet are available. Among the best known : Marine Traffic, Vessel Finder, SiiTech, LocalizaTodo, and many others. One of these networks especially stands out, AIS Hub, an AIS NMEA data sharing center, which provides developers with an API for integration of its network in 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 →

Since 30 September 2018 (*), I already had information regarding the abandonment NAVX Studio LLC for the development of two historical applications created by Richard Ray : GPSNavX and MacENC. The buyers of these applications and iNavX had clearly announced focuse only to the development of iNavX, on iOS and Android. It is likely that applications on Mac no longer had any profitability, especially with the loss of Navionics charts for MacENC. Read more →

VMG / VMC – for Dummies

Navigation applications are full of acronyms. This coded and cryptic language was originally developed for electronic navigation instruments, GPS mapping and other chartplotters. These acronyms, in the form of three letters most often, are the contraction of terms defining specific navigation data and according functions. This facilitates on-screen display taking few space. While some of these acronyms are relatively well assimilated by the boater, as SOG for Speed ​​Over Ground (SOG), you can quickly access subtleties that are not always mastered as COG for Course Over Ground, meaning "route runned on the ground", that the word "Course" in English can mean "Route" or "Heading" according to the context.
