Student placement

Integration of GNSS in a Navigation Prototype for Tracking First Responders

Pedestrian Navigation and Tracking

Starting date

1 January 2024

Duration of contract

6 months

Remuneration

up to German TVöD 5

Type of employment

Full-time (part-time possible)

In indoor emergency situations, such as a building on fire, usually the first responders enter in small teams the building without knowing the floorplan. At the same time, the commander of the first responders on sight needs to know the positions of the first responders in the building to coordinate their actions. Therefore, DLR developed a pedestrian dead reckoning (PDR) solution based on inertial measurements with a sensor located on the foot. The PDR positions have to be communicated reliably to the central command. 

The complete wearable PDR system is integrated into a small prototype. It includes the inertial sensor, a CPU/microcontroller for the PDR algorithm, and a Wi-Fi unit for transmitting the positions to a second transmitter box. The additional transmitter box contains a LoRa transmitter unit to send the signals to the central unit. For the overall system a GNSS unit has to be integrated and tested. The GNSS unit is necessary for obtaining the starting position and direction for initializing the inertial positioning system, and for sensor fusion outdoors – if GNSS data is available.

Your task is to test and design additional commercially available GNSS units either integrated in the PDR prototype or in the LoRa transmitter prototype. In detail, your tasks are: 

• prepare and test existing GNSS boards for providing additional GNSS based localization data for sensor fusion. Research extensively possible solutions for integrating a GNSS tool
• test extensively the LoRa communication technology, investigate the communication performance and analyze advantages and disadvantages

• study of electrical engineering, computer science or similar
• excellent knowledge of communication theory
• excellent knowledge in programming (Python, C, Java)
• extensive hands on experience with experimental hardware platforms, e.g. Raspberry PI or Arduino

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
