This tool emulates a running instance of gpsd. It generates random movements based on a simple algorithm. Primary use case for it is testing of software which uses gpsd, but it can also be used for demonstration purposes. It is implemented in Javascript using nodejs.

npm install -g gpsd-fake

Run it as follows:

gpsd-fake --port [port] --config-file [config-file] --tmp-file [tmp-file]

• -port: Is the port to bind to, if not supplied it defaults to 2947
• -config-file: Supply minimum and maximum values for latitude and longitude. You can configure the speed in kilometers per hour, also. See https://github.com/loewexy/gpsd-fake/blob/master/config.json for an example. Might be a just a filename, a relative or an absolute path.
• -tmp-file: Is a file in which gpsd-fake will regulary save its state, so you can restart the tool and proceed at the same position. Might be a just a filename, a relative or an absolute path. This feature is disabled by default.
