iNavX and iSailor offer more functions

The year 2015 barely begun, developers already deliver us their applications developments, probably developed between two glasses of champagne during the holidays. I consider iNavX and iSailor as the two best navigation apps so far under iOS. These are the ones that offer the most extensive functions and the selection of the best charts. They each have their qualities and their defects, and I took advantage of the innovations introduced by their recent update to attempt a quick comparative price/functions.

Warning, this exercise is associated with a snapshot vision, valid today but quickly obsolete tomorrow, as changes are rapid in this domain. On the other hand it is always difficult to share the objective and subjective aspects in a comparative, I was already confronted in the past (¹). (continue…)

New GFS grid 0.25° model

By a notification corrected the 23 December 2014 (¹), the NWS (National Weather Service) NOAA has announced a major update of its weather predictions GFS model to be effective in mid-January 2015. Actually, This model is partially available on an experimental basis since early December.

NOTE

On March Global Forecast System (GFS) is a model of weather forecasts produced by the National Centers for Environmental Prediction (NCEP) dependent of the NWS. Dozens of variables (²) atmospheric and terrain are available through this data set, Since temperatures, winds and precipitation to moisture from the soil and the concentration of atmospheric ozone. The world is covered by the current GFS model with a horizontal resolution 27 km between grid points to 10 day. The horizontal resolution is 70 km for forecasts between one week and two weeks. The GFS model is a coupled model, composed of four distinct models (an atmospheric model, an ocean model, an Earth model, and a sea ice model), who compete together to give an accurate picture of weather conditions. Changes are regularly made to the GFS model to improve the performance and accuracy of forecasts. Gridded data are available for download via the NOMADS servers (National Operational Model Archive and Distribution System) and widely used by application developers in the world.

Iridium Mail & Web is once again fully usable

Since release Apple iOS 8 early October 2014 the app Iridium Mail & Web application (which replaced Iridium Mail & Web application) was no longer able to export an attachment in another application by the function "open in".… ". This fact could no longer use a weather GRIB file received as an attachment from the SailDocs server in any application, mainly Weather4D PRO. It took more than 3 month for two successive updates come correct this problem severely handicapping for client users of Iridium :

[SHIFT-2 of 6 January 2015] Version 1.0.9 fixes bugs display and delete messages (removing rotation, too strong !).
