NMEA Generator: A drawing tool for creating GPS logs

Posted by Diego Assencio on 2017.01.06 under Technology (Maps)

NMEA is a standard which is widely used for representing GPS position information in textual form. This standard defines a set of one-line sentences which are independent from each other and contain information such as position, velocity and time.

Given the broad range of applications which are capable of understanding NMEA data, I decided to create a tool for manually drawing a path on a map representing an object or person moving around while carrying a GPS device which gives them their current position at regular time intervals (e.g. once every second). This path can then be stored as an NMEA file, i.e., as a text file containing NMEA sentences which represent the position information for all points in the path.

The tool is called NMEA Generator. I hope you will put it to good use, and should you have any questions, please don't hesitate to write a comment below or send me an e-mail. Enjoy it! :-)

Will try some test with a app for my private use.

Hi, since not having a mfd to generate nmea route sentence from gpx file generated by a nav app, only have ipad, need an app that can send nmea route sentences straight to my autopilot over wifi bypassing mfd, will your neat nmea generator work? Cannot find send/start, only download...

@Magnus: The NMEA generator only produces NMEA sentences on a downloadable file. Perhaps you can use another application to stream the contents of that file to your device?
