[Termes IGN] topométrie de précisionRésumé : (auteur) In the era of multiple satellite navigation and positioning, there are still many remained issues to be tackled in order to satisfy varied applications for various sectors. These include availability, accuracy, integrity, vulnerability and others. To explore feasibility of deformation monitoring under dam and steep slope environments, we investigated features of hybrid BD / GPS positioning and monitoring performance. Results indicate that hybrid satellites can further facilitate precise positioning for deformation monitoring on restricted regions. A static network in near real time mode is designed to exhibit essential sensitivity for deformation monitoring under different network connectivity. Analysis shows that under given network design matrix, contributions from hybrid BD / GPS have enhanced network sensitivity and ensured monitoring performance under challenged scenarios. Related tests combining with application to stringent dam monitoring have been conducted to exemplify sensitivity changes along vital engineering directions and optimal schemes for network configuration.

[Termes IGN] transportRésumé : (Auteur) Rooted in the philosophy of point- and segment-based approaches for transportation mode segmentation of trajectories, the measures that researchers have adopted to evaluate the quality of the results (1) are incomparable across approaches, hence slowing the progress in the field and (2) do not provide insight about the quality of the continuous transportation mode segmentation. To address these problems, this paper proposes new error measures that can be applied to measure how well a continuous transportation mode segmentation model performs. The error measures introduced are based on aligning multiple inferred continuous intervals to ground truth intervals, and measure the cardinality of the alignment and the spatial and temporal discrepancy between the corresponding aligned segments. The utility of this new way of computing errors is shown by evaluating the segmentation of three generic transportation mode segmentation approaches (implicit, explicit–holistic, and explicit–consensus-based transport mode segmentation), which can be implemented in a thick client architecture. Empirical evaluations on a large real-word data set reveal the superiority of explicit–consensus-based transport mode segmentation, which can be attributed to the explicit modeling of segments and transitions, which allows for a meaningful decomposition of the complex learning task.

[Termes IGN] table géodésiqueRésumé : (auteur) PPP-RTK has the potential of benefiting enormously from the integration of multiple GNSS/RNSS systems. However, since unaccounted inter-system biases (ISBs) have a direct impact on the integer ambiguity resolution performance, the PPP-RTK network and user models need to be flexible enough to accommodate the occurrence of system-specific receiver biases. In this contribution we present such undifferenced, multi-system PPP-RTK full-rank models for both network and users. By an application of S-system theory, the multi-system estimable parameters are presented, thereby identifying how each of the three PPP-RTK components are affected by the presence of the system-specific biases. As a result different scenarios are described of how these biases can be taken into account. To have users benefit the most, we propose the construction of an ISB look-up table. It allows users to search the table for a network receiver of their own type and select the corresponding ISBs, thus effectively realizing their own ISB-corrected user model. By applying such corrections, the user model is strengthened and the number of integer-estimable user ambiguities is maximized.
