    Opis:
    This article presents a system of precise navigation for a visually impaired person which uses GPS navigation and an infrared sensor in the form of an infrared matrix. The presented system allows determining the orientation and distance of a blind person relative to a selected object, e.g. a wall or road edge. The application of the above solution facilitates a significant increase in the accuracy of determining the position of a blind person compared to the accuracy offered by commonly used ground satellite devices. The system uses thermal energy accumulated in the environment without the need to generate additional signals. The main parts of the system are a simple infrared matrix, data processing system and vibrating wristband. Messages and navigation warnings are sent to a blind person in the form of a vibration code. The article describes the method of determining the path of a specified width and distance from the wall of a building, curb, etc., along which a blind person should move. The article additionally describes the method of determining the orientation of a blind person depending on the selected object. Such a method facilitates verifying whether the visually impaired person is moving according to the indicated direction. The method can also be used to navigate mobile robots. Due to the use of natural energy for data registration and processing, the mobile navigation system can be operated for a long time without the need to recharge the battery.

    deformation of objects
    Opis:
    For almost two decades scientists from couple of world famous universities have been working on using satellite navigation data to detect deformations and movement parameters of big structures like tall buildings, long bridges or dams. Evaluation of software and hardware solutions dramatically increases spectrum of construction parameters which can be investigate using GNSS technology. This process is changing very dynamically and brings a lots of possibilities for construction specialist who investigates buildings structures. Today many Structural Monitoring Systems includes high-rate GNSS receivers and software able to calculate phase measurements to sub centimeter level. This paper introduce first test of measurement system based on Global Navigation Satellite System technique and Real Time Kinematic method.

    silvicultural planning
    measurement error
    Opis:
    In detailed silvicultural planning, good knowledge of the internal situation (e.q. placement of advanced regeneration) in stand survey units is necessary. Information gathered in the framework of regular forest survey is not sufficient, specifically when natural stand regeneration is planned. The application of GPS is a practical, inexpensive, quick to operate technology of collecting information required for silvicultural planning and positioning spatial elements of a cutting system. As silviculture needs do not require such a high accuracy as in the case of positioning of stand survey units, it seems that the application of tourist−class GPS receivers is an optimum solution. This class equipment is inexpensive and easy to operate. The knowledge about possibilities which GPS receiver provides on the one hand and the awareness of limitations that forest environment creates for GPS measurements helps make a reliable draft of a stand's internal situation.
