Method and assessment of BDS triple-frequency ambiguity resolution for long-baseline network RTK

Advances in Space Research, 2017
Abstract Fast and reliable ambiguity resolution (AR) over long baselines is one of the major challenges for large-scale GNSS network real-time kinematic (RTK) positioning. In the dual-frequency case, wide-lane (WL) ambiguities are usually fixed firstly, followed by the procedure of determination of the narrow-lane (NL) ambiguity integers based on the

Triple Change Detection Network via Joint Multifrequency and Full-Scale Swin-Transformer for Remote Sensing Images

IEEE Transactions on Geoscience and Remote Sensing, 2023
Although deep learning-based change detection (CD) methods achieve great success in remote sensing images, they still suffer from two main challenges. First, popular Convolutional Neural Networks (CNNs) are weak in extracting discriminated features focusing on changed regions, since most methods ignore the multi-frequency components of bi-temporal ...

A novel triple-frequency controlled lamp network with end-of-life detection for architectural dimming of compact fluorescent lamps

APEC '99. Fourteenth Annual Applied Power Electronics Conference and Exposition. 1999 Conference Proceedings (Cat. No.99CH36285), 1999
Ballast designers face great difficulty in trying to dim the compact fluorescent lamps (CFLs) below 40%. The symptom is a lamp current oscillation which results in excessive flickering. This is due to the fact that CFLs are known to exhibit high negative resistance during dimming. Also, CFLs tend to draw excessive power at the end of their useful life.

Triple band frequency selective surface design for 5G mm‐wave communication with artificial neural networks

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields
AbstractHigh‐performance frequency selective surfaces (FSSs) have gained attention for their spatial filtering characteristics in 5G communication systems. In this work, we propose an efficient and accurate design methodology for the FSS. Three different artificial neural network methods (ANN) are employed, and their performances are compared for ...

Network-based triple-frequency carrier phase ambiguity resolution between reference stations using BDS data for long baselines

GPS Solutions, 2018
Network-based ambiguity resolution (AR) between reference stations is the prerequisite to realize a precise real-time kinematic positioning service. With the help of BDS triple-frequency signals, we can efficiently deal with the ionospheric delay and tropospheric delay, and achieve rapid and reliable AR.
