Cost-effective GNSS receivers for geodetic monitoring : doctoral dissertation = Uporaba cenovno ugodnih sprejemnikov GNSS za geodetski monitoring : doktorska disertacijaHamza, Veton, geodezijaFor numerous years, geodetic techniques and sensors have been applied to determine and monitor deformations of engineering structures and natural hazards. GNSS instruments have been classified as ... suitable sensors for monitoring applications due to their ability to provide continuous monitoring of movements with high accuracy. Nevertheless, the implementation of geodetic GNSS instruments in high-risk areas may be deemed costly, with prices ranging up to several tens of thousands of euros. In certain situations, multiple GNSS instruments need to be installed, further increasing the cost by several hundred thousand euros. Instead, low-cost GNSS receivers are being considered as an alternative to high-quality geodetic GNSS receivers for such applications. A few years ago (in 2019), low-cost dual-frequency GNSS receivers were introduced to the market, drawing the attention of numerous researchers in the geodetic field. These GNSS receivers, capable of tracking satellite signals in both frequencies, offer the advantage of compensating for the ionospheric delay, leading to their increased use across different applications. Low-cost GNSS instruments now have the ability to provide real-time kinematic (RTK) positioning solutions and are compatible with geodetic GNSS antennas, making them comparable to high-quality geodetic GNSS instruments. The findings of the doctoral dissertation indicate that low-cost GNSS instruments currently do not provide observations of the same quality as geodetic GNSS instruments, but rather slightly inferior. Nevertheless, these GNSS sensors can obtain positioning with an accuracy that is acceptable for many survey projects. Low-cost GNSS instruments were used to develop a low-cost GNSS monitoring system for geodetic monitoring applications. The developed LGMS represents a suitable solution for near realtime continuous monitoring with high accuracy while significantly reducing costs. To validate its performance, the LGMS was tested in monitoring the Laze landslide over six months from where its functionality was proven. Furthermore, it can be applied for monitoring other engineering structures such as viaducts, bridges, dams, mining areas, and chimneys, as well as natural hazards like subsidence and landslides, provided it meets the accuracy requirements. By implementing low-cost GNSS technology, monitoring expenses can be reduced, facilitating the monitoring of more natural hazards and structures in the future. By employing low-cost dual-frequency GNSS instruments, we are progressively approaching the positioning quality level of geodetic GNSS instruments, which are significantly more expensive, ranging from twenty to forty times the cost.Vrsta gradiva - disertacija ; neleposlovje za odrasleZaložništvo in izdelava - Ljubljana : [V.
