Systems - Electronics Slug: nmea-data-sharing-across-applications-and-platforms Status: published

With a Maretron USB100 NMEA-0183 Gateway and an Actisense NGT-1 NMEA 2000 gateway I was struggling to get the NMEA data to all the applications on my PC, iPAD and iPhone. Many applications can not only connect to the an NMEA data source but also share the data on another TP Port or Virtual Com Port. Originally I was using a complicated stack of software all connected to each other to get data to some of the applications but couldn’t really use them all at once. More importantly which ever app I felt like using at the time might require starting up two applications!

Well in comes GPSGate Client (\$40) which lets you connect to a data source and then share it with many other applications.

You can see in the graphic below that I’ve dedicated the Actisense Gateway to Coastal Explorer. GPSGate is then connected to the Maretron Gateway and then it is used to serve up the data to 7 other applications some on Windows and some on my WiFi iPad and iPhone.

Also of note is that my preferred iOS navigation application Navionics works fine on the iPhone since it has a built-in GPS, but on the WiFi iPad there’s no way to get the NMEA data into the application. I’ve contacted Navionics about this and we’ll see if they add the functionality.

This is greatly simplified from the way I was doing it before and I’m very excited to not only have all this finally working but to have it working simply! \$40 for GPSGate was worth every penny!
