Prediction of phase ambiguity resolution based on signal intensity and geometry

The goal of this contribution was to develop a reliable quality indicator reflecting the potential success of differential carrier phase ambiguity resolution for kinematic Global Positioning System (GPS). The indicator must be operable without any communic ...

Cell-Based Deformation Monitoring via 3D Point Clouds

Jing Wu

Deformation is one of the most important phenomena in environmental science and engineering. Deformation of artificial and natural objects happens worldwide, such as structural deformation, landslide, subsidence, erosion, and rockfall. Monitoring and asses ...

Algorithm for Flow Direction Enforcement Using Subgrid-Scale Stream Location Data

Producing realistic surface water flow patterns can be difficult for hydrologic models when there is insufficient grid resolution as a result of computational constraints or when available digital elevation model (DEM) data are relatively coarse. This tech ...

The IceCube data acquisition system: Signal capture, digitization, and timestamping

Xiaoxia Bai

IceCube is a km-scale neutrino observatory under construction at the South Pole with sensors both in the deep ice (InIce) and on the surface (IceTop). The sensors, called Digital Optical Modules (DOMs). detect, digitize and timestamp the signals from optic ...

Distance preserving flattening of surface sections

Roger Hersch, Laurent Saroul

Curved cross-sections extracted from medical volume images are useful for analyzing nonplanar anatomic structures such as the aorta arch or the pelvis. For visualization and for performing distance measurements, extracted surface sections need to be adequa ...

Custom GPS-Correction Server for Real-Time Trajectography

Hervé Gontran

Centimeter-level real-time kinematic (RTK) positioning is one of the most widely used surveying techniques. Broadcasting GPS-RTK corrections via Internet-based services has become a new communication procedure to achieve “instantaneous” positioning with hi ...
