Goals to be achieved

The Institute of Flight Guidance (IFF) contributes its expertise in inertial navigation technologies to the TRIPLE enterprise, aiming to ensure robust and safe navigation of the nanoAUV under ice.

Tasks within the project

  • Specification analysis regarding the navigation sensor suit
  • Proposal of suitable sensors
  • Concept for a rugged and failure tolerant Attitude and Heading Reference System (AHRS)
  • Conceptual design of a surveillance system to monitor navigation solutions and  navigation critical sensors

Preliminary work (with one graph or one picture)

Engineering suitable solutions for the tasks mentioned above will be facilitated by resorting to the IFF’s vast range of experience with regard to inertial and GNSS aided navigation applications, including safety critical applications within the aviation and automotive domain. Recent examples are the C2Land project for vision augmented INS/GNSS based landings (Figure 1, left), airborne mapping and inspection of harbour crane tracks with millimetre accuracy (Figure 1, right) and high automated driving functions for the automotive industry.

Implementation steps

  • Once all requirements regarding the navigation performance have been gathered, the overall sensor need is determined and potential sensors will be selected with respect to design, function and access constraints.
  • On the basis of the selected sensor suit a bespoken AHRS algorithms will be selected in order to provide a rugged fall-back solution within the multi-level navigation system that will be developed with multiple partners.
  • Suitable indicators will be examined and selected in order to capture degradation of navigation critical sensor data. This is the essential prerequisite to choosing the most appropriate navigation solution.
  • The eligibility of the developed algorithms and possible adjustments will be investigated within simulations and joint test undertakings.
