Prediction of Fixing of RTK-GNSS Positioning in Multipath Environment Using Radiowave Propagation Simulation

Simulation of Radiowave Propagation Using Propagation Models

In this article we review the fundamental issues involving the simulation of the radio channel and discuss some of the more challenging simulation topics that are pertinent to the radio channel. Radio and propagation channels The propagation channel, together with the transmit and receive antennas, constitute the radio channel. Figure 1 depicts the propagation and radio channel's place in a rad...

Multipath Propagation, Characterization and Modeling in GNSS

Radiowave Propagation Measurements and Prediction in Bushfires

Australian vegetation is fire-prone. Every year, wet and dry sclerophyll forests of Western Australia, southeastern Australia and grassland ecosystems of the northern part of the continent are subject to high intensity fires. The sclerophyll vegetation contains up to 2.71 % of the element potassium. The element exists in plants’ organic matrix: attached to the oxygencontaining and carboxyl func...

High-Accuracy Positioning in Urban Environments Using Single-Frequency Multi-GNSS RTK/MEMS-IMU Integration

The integration of Global Positioning System (GPS) real-time kinematics (RTK) and an inertial navigation system (INS) has been widely used in many applications, such as mobile mapping and autonomous vehicle control. Such applications require high-accuracy position information. However, continuous and reliable high-accuracy positioning is still challenging for GPS/INS integration in urban enviro...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
