Methods of radio position determination on short distances

  • Branch of study: Electrical Engineering and Communications
  • Department: Department of Radioelectronics
    • Description:
      It is expected now that requirements on precision of position determination will be fulfilled by satellite navigation system. However it is not accomplished in local applications in hard conditions of signal reception. This is a reason for application of so called Signal of Opportunity. An aim of work is to investigate these methods and to work up the optimal ones.

Multisystem radio position determination in hard condition

  • Branch of study: Electrical Engineering and Communications
  • Department: Department of Radioelectronics
    • Description:
      Reception of GNSS signals in buildings, under ground or rubbles is called as hard conditions of reception. They are called also the indoor navigation. We use for them proprietary methods instead standard ones. It is necessary to combine their local coordinates systems with global ones, e.g. WGS 84.

Optimum hardware and software for radio systems of position determination and navigation

  • Branch of study: Electrical Engineering and Communications
  • Department: Department of Radioelectronics
    • Description:
      It is supposed at present time that position determination is provided by satellite systems namely by GPS. It can be combined with GLONASS, Galileo and BeiDou systems into so called multiconstellation one. The multiconstellation systems can be supported by terrestrial systems. The main task of work is to find optimal constellation.

Radio circuits of GNSS receivers and their realization

  • Branch of study: Electrical Engineering and Communications
  • Department: Department of Radioelectronics
    • Description:
      Optimization methods of front ends of GNSS receivers. Low noise antenna amplifiers, signals splitters, mixers. Their analysis, simulation and integration.

Radio position determination systems and their ammendment for higher precision

  • Branch of study: Electrical Engineering and Communications
  • Department: Department of Radioelectronics
    • Description:
      It is necessary to support satellite methods of position determination by special signal when we need precision of tens of centimetres. These signals especially signals using phase, can contribute to availability of service, too.

Satellite navigation backup system

  • Branch of study: Electrical Engineering and Communications
  • Department: Department of Radioelectronics
    • Description:
      Important problem of satellite navigation systems use is intentional jamming especially in air and sea transport. Methods and systems resilient to jamming are searched for. Favourable system is eLORAN, or LORAN C. The issue of work is the optimal signal processing of eLORAN signals. See http://www.insidegnss.com/node/3769
