I recently bought a "SkyRC GSM-015 GPS speed Meter" to check the altitude of my planes etc.
If you have one of these and have used the SkyRC GNSSLogger application you will know that the application is quite basic.
It allows you to save projects and also has the option to export paths to a KML file. The KMLexport facility though doesn't allow you to set options (path name, line colour, line width etc.). I have created a small web-app that will allow you to upload a project file (.3gpl), set some parameters and then convert it to a kml file.
The app can be accessed via the Applications menu to the left.
