Navigation by hybridization of magneto-Inertial and dynamic corrections

Sysnav’s promise is to provide available, accurate and integrated geolocation for light applications without relying on an  infrastructure and which operates in all  environments, even the most extreme, including GPS denied areas such as indoor or near-indoor.

This promise is based on disruptive technology, magneto-inertial navigation, which allows to measure in 3D (requiring no infrastructure) the speed of a device in which the environment presents stationary magnetic disturbances. This is a key building block in dead-reckoning navigation architecture since it is the only one which enables to take into account all of a pedestrian’s dynamics; in particular, it presents no dependencies on the type of movement being considered.

Sysnav has been working for 9 years to evolve this building block via successive feasibility studies. This approach has led us to fully understand the limitations of this technology that make coupling with other building block relevant to the mission, as well as its unique advantages that make it difficult to substitute. Since 2009, the company has invested in the development of building block that are perfectly identified and complementary to the TMI, relying on strong partnerships with an academic laboratory for each building block.

The TMI-REDY project for Magneto-Inertial Tachometers coupled with the Dynamic Speed ​​Realignment by proposing the coupling of two dead-reckoning navigation technologies with navigation realignment via a non-reliable infrastructure (GPS type) makes it possible to meet the stakes of locating a pedestrian in a non-collaborative environment. This is perfectly in line with Sysnav’s scientific and technical roadmap strategy, which is supported by its academic partner for learning, the DataShape team at INRIA Saclay.
