Resumen:
Una universidad polaca ha desarrollado un sistema para realizar medidas con GPS mediante el uso de transmisores terrestres (pseudosatélites). La ventaja del sistema es la capacidad para realizar medidas con GPS en lugares de difícil acceso y con poca visibilidad de la esfera celeste, así como mejorar la productividad laboral reduciendo el tiempo de medida y eliminando parte de las medidas clásicas adicionales. Este método se utiliza en ingeniería de medidas y estudio de desplazamientos y deformaciones en la construcción de sistemas de alerta temprana sobre los riesgos asociados a diferentes diseños de ingeniería. La universidad busca socios con el fin de establecer acuerdos de cooperación en materia de investigación.

Tittle:
Application of pseudo-satellites in engineering measurements
Summary:
A university from North-East of Poland has developed a system supporting GPS measurements by using terrestrial transmitters (pseudo-satellites). Advantage of this system is the ability to measure GPS in places out of reach, with poor visibility of the celestial sphere, as well as improvement of labour productivity by reducing measurement time and eliminating part of additional classical measurements. The university is interested in research cooperation agreement.
Description:
The university was founded on 1 September 1999 in Olsztyn, Poland. At first, in 1999, there were 12 faculties, 32 branches of study, and 24.500 students. Now there are over 27.000 students that are educated at 17 faculties, and 65 branches of study, within either full-time or part-time studies. Additionally, there are also 600 doctoral candidates, and 1500 post-graduate students. Department of geodesy provides a wide range of research from the use of GPS, satellite observations up to geodetic network adjustment.

Using GPS measurements in engineering has increased work pace and reduced its costs. Satellite measurements provide sufficient accuracy of determining horizontal components (up to a few millimeters), however height measurement is burdened with an error several times bigger which often prevents the use of GPS system in precise geodetic measurements. Necessity of performing measurements at "open" sky is also a limitation. Obstacles in the form of buildings, trees etc. hamper the quality of designating position and often make it impossible to perform the measurement.
The method developed by scientists of the department can be a solution to this problem. Standard GPS observations supported by pseudo-satellites can eliminate disadvantages associated with poor availability of satellites without need for additional conventional measurements and ensure the required accuracy in comparable time to the time of measurement without obstacles.

The university looks for research cooperation agreement on the further development of this technology (with the construction of its terrestrial GPS transmitter).
Advantages and Innovations:
Pseudo-satellites are devices that send the same signal as the GPS satellites placed on the ground with known coordinates. The idea of using GPS receivers anywhere it was so far not possible (even inside buildings) is a significant innovation in the field of geodetic GPS measurements. The method may be used in measurement engineering, study of displacements and deformations in building early warning systems about the risks associated with different engineering designs.
Stage of Development:
Under development/lab tested

Partner sought

Type and Role of Partner Sought:
The university is looking for research cooperation on the use of a system consisting of one or more pseudo-satellites for measurements in difficult terrain. This means that the partner sought can be a research unit or a company dealing with geodetic measurements.
