Using an OBD-II connector for acquiring the velocity information from a (chosen) car
In particular, the connector ELM327 OBDII USB V1.5 PC will be used.
Some more info about OBD-II: https://en.wikipedia.org/wiki/On-board_diagnostics. There seems to be a wealth of software tools for OBD-II, presumably most of them will not be usable. Ideally we need something very low-level, suitable for scripting with Python or Matlab or Julia.
The velocity data will be turned into pulses acceptable for the GNSS receiver uBlox ZED-F9R.
Alternatively, the data will be converted to a CAN message ready to be sent to the GNSS receiver.
