Our Purpose
The research the Navigation group working in the laboratory of Aerospace Information Systems (hereinafter referred to as NavLIS and part of the Department of Measurement) is engaged in has as its main objective the increased security of the civilian sector from the perspective of accurate navigation in applications aimed at a ground and air resources.
Therefore, our goal is to increase the accuracy of the implemented navigation task, not only from the perspective of the 3D position but also the orientation defined Euler angles or quaternions. Algorithms for the calculation of the mentioned parameters are already theoretically known. The practice, however, gets more complicated from the perspective of different dynamics and applications, the influence of the environment on the measurement systems and the imperfections of the measurement systems or sensors used.
In the NavLIS framework, we are trying to develop the algorithms of these aspects so as to minimize their impact on the accuracy of the evaluation. The applicability of the units we have designed and implemented is wide.
Our navigation units can be deployed on air and ground devices, to provide an overview of a situation (for example, during floods and fires), for the monitoring of land-based objects, for rescue operations as a guidance system for helicopters, to increase the security of critical infrastructures (power plants and grids, chemical and nuclear industries, ammunition depots), for the protection of airports, as the backup system for the selected tasks of air traffic control, etc.
