It's a dedicated Marine linux OS
Dedicated Marine OS
Xinutop-nav is a Linux portable or installed marine OS, including a lightweight base applications from Xfce family, and provide, with less of 400Mo, essential marine applications such as:
Fldigi: reception and display radio weather-fax and NAVTEX, via the sound card.
OpenCPN: chartplotter, tides, AIS, grib files, GPS interface and others navigation datas (dashboard).
Polarcom: virtual instrumentation, from NMEA datas.
XTide: tides with numerical and graphical display, worlwide coverage.
Zygrib: download and display weather grib files.
Muplex: NMEA multiplexer.
OSD Depth: display water depth with big digits above any application (aka "on top").
Xinutop is made with a special care of lightness, simplicity, efficacy, reliability and can operate from multiple datas supports (HDD, SSD, USB, Flash) on a great variety of i386 compatible computers, specially with low power processors, or those unfairly considered as obsolete, poorly supporting the growing greed of currents OS, less and less compatible with embedded hardware. Xinutop can run as a portable operating system on removable device, but also as a main operating system on hard drive (same install). The memory usage after startup is about 100MB. To make Xinutop unbreakable (may I say "unbrickable" - used term for deads tablets - or almost ?), the necessary system files and directories are locked and can't be deleted or modified by a normal way (even in root mode).
Xinutop is assembled with Ubuntu 12.04 packages (Precise), including the scripts "lrd" by Gauvain Pocentek and provide:
It also has other stuff listed on the site like.
MUPLEX is a Linux soft multiplexer that can mix different input flows of real or emulate serial datas NMEA and share it between multiple applications.
OSD echo-sounder display
OSD DEPTH is a Linux echo-sounder repeater which uses the OSD (On Screen Display) technique to display the water depth from NMEA sentences as DBT (Depth Below Transducer) or DPT (Depth). See screen copy at top of document.
Raster charts organizer
