    Actual Status - Researches

    1. The establishment of the Baseline Calibration

    Station for GNSS Antennas at UFPR.

    The first service in Brazil and Latin America.

    The calibration basis was possible especially due to

    technology transfer from Germany within the international

    cooperation PROBRAL: Precise positioning and height

    determination by means of GPS Modelling of errors and

    transformation into physical heights, which was funded by

    CAPES (Brazil) and DAAD (Germany) (GIK/UFPR).

    Actual Status - Researches3. Technology Innovation

    Developed a material called Attenuator of Multipath Effect (AEM-

    LAGE) that might be coupled to an antenna in order to decrease

    the multipath effects and mitigate the indirect signals that reach the

    positioning receiver.

    Prototypes of monitoring devices for water levels and currents in

    coastal and the barrages waters. The prototypes was tested in

    Vossoroca reservoir. Can be verified that the prototypes were

    efficient in collecting data and that these, post-processed,

    represent, within the precision of the equipment used, the reality

    of hydraulic dynamics of the test area.

    The prototypes provide data shall go through the analysis of

    velocity fields, which supplied research support for the LAGE to

    determine fragility of coastal areas of environmental

    preservation supported by specialists systems.
