Dead Reckoning (DR) is a technology to determine a unit's absolute position from an outdated absolute position and recent sensor data. A common automotive use case is to determine the position of a vehicle while driving in a tunnel where there is no GNSS (e.g. GPS) reception. Typically this has been done using a Kalman filter, wheel tick data, steering angle data, accelerometer and gyro This works well but requires a substantial integration and tuning work for each vehicle model.

Recent research ( GitHub - mbrossar/ai-imu-dr: AI-IMU Dead-Reckoning ) has shown an opportunity to remove the dependency on vehicle specific data and models by combining the Kalman filter with a neural network.


A dead reckoning solution for ACTIA's ACU6 platform which requires minimal integration and tuning, therefore applicable also for low volume applications.

This thesis will be a first step towards that goal.


Note that the later steps below are depending on previous steps and may not be possible at all. Therefore a first project should aim only for step 1.

Step 1 - Apply the research algorithms to ACTIA hardware

Investigate whether the referenced algorithms can produce sufficient quality output also with the sensors of a mass produced telematics unit (ACTIA's ACU6 unit). The work will include

  • Writing data collection software in the ACU6 and/or a connected PC
  • Connecting a reference GNSS receiver (RTK supported) for collecting "true position"
  • Collecting real drive data
  • Applying (off-line) the proposed algorithms
  • If needed, investigate adaptations of the algorithms to improve the output.

Repeat the analysis with a high quality automotive GNSS receiver using RTK technology (already available in some vehicles)

Needed skills: Good understanding of Kalman filtering and neural networks. Basic programming (Python, shell scripting). Systematic and scientific mindset.
