Welcome to the OpenSkipper project, which provides Open Source C# code for Windows for integrating and displaying NMEA 0183, NMEA 2000 and AIS data from nautical instruments, GPS units and internet data sources. OpenSkipper can be run on a laptop aboard your boat to show electronic instruments displaying speed, heading, etc. Open Skipper can also receive and transmit data over multiple connections, including a serial port (for NMEA 0183), an ActiSense NGT-1-USB NMEA-2000-to-USB converter to read NMEA 2000 (N2K) data, and wired and wireless network connections (including TCP and UDP). It also contains a built-in webserver, so you can run OpenSkipper on a laptop and use this to display data on an iPad or Android phone or tablet.
OpenSkipper was initially developed by Dr Andrew Mason in the Yacht Research Unit and Dept of Engineering Science at the University of Auckland, New Zealand, with fantastic assistance from student Jason Drake. OpenSkipper was updated in 2014 by Timo Lappalainen and Kave Oy from Finland.
If you are interested in the NMEA 2000 standard, then Open Skipper provides both code and definition files for interpreting NMEA 2000 messages. This work uses the definition files developed byCanBoat project.as part of his excellent
NMEA 2000 messages can be received using the Actisense (www.actisense.com) NGT-1-USB NMEA-to-USB converter (a product that we recommend). We have not signed any non disclosure agreements with Actisense, but instead written our own low level COM-port driver. Our accessing of an NGT-1 in this way is not officially supported by Actisense. It works for us, but we take no responsibility in any way for any consequences.
Open Skipper contains XML definition files used to describe how an NMEA 2000, AIS and NMEA 0183 message should be decoded. These definition files are a beta release, have not been tested and contain errors, so please do not rely on any output from open skipper for your navigation. These definitions are unofficial, and are not supported by NMEA (www.nmea.org) or any other body in any way. We welcome community feedback on improvements to these.
Open Skipper is beta software designed to serve only as an aid for navigators. It in no way replaces the need to follow good nautical practices.
