Delivering GPS corrections via Internet-based services has become a new communication procedure to achieve centimetre positioning accuracy in real time. A usual implementation within a fixed installation implies NTRIP (Networked Transport of RTCM via IP Protocol) and IGDG (Internet-based Global ...
positioning errorbidirectional antennasensorWireless indoor localizationZigbeeEnvironmental changes and obstacles are two main factors affecting the accuracy of indoor positioning in wireless indoor localization. The multi-mode sensor positioning had been used to increase accuracy but at high costs. The ...
High-Precision Indoor Positioning: The Ai-Thinker DW3000 UWB module offers centimeter-level accuracy for indoor positioning, enabling precise location tracking and navigation in various applications. Compact Design: With a compact size of 23x13x3mm, this module is ideal for integration into space-cons...
(SVM) classifier model to predict which direction the wave was traveling at a given timepoint. We used randomly drawn timepoints comprising equal group sizes to train the model with 5-fold cross-validation (80% train, 20% test). Prediction accuracy surpassed the 99% CI (shuffled group ...
mitigate training and validation issues in complex scenarios. Minglei Du et al. developed an error model for the positioning algorithm, provided a method for calculating the shared Position Dilution of Precision (PDOP), and validated the accuracy of the error model through simulations using Monte ...
AdamW is a variant of the Adam optimizer that has an improved implementation of weight decay and computes an adaptive learning rate for each parameter. Our proposed model produces an accuracy of 82%. It was concluded that our approach outperformed the existing algorithm: BERT having an accuracy ...
Additional explanations of the mechanical and positioning accuracy and limitations of the SFG can be found in Sandmeier (2000). Target sampling was conducted at regular one-hour intervals throughout the day. Changes in the Sun's zenith position during the March field campaign ranged from ~12° ...

To overcome the issue of unable to recognizing new sentences, the developed segmentation AI frame splits the entire sentence signals into word units and then recognizes all the signal fragments. Inversely, the whole sentence’s information can be reconstructed and recognized with an accuracy of ...
Multi-channel enhancements improve TSync's performance. We deploy a GPS-enabled framework in live sensor networks to evaluate the accuracy and overhead of TSync in comparison with other in-situ time synchronization algorithms. 展开 DOI: 10.1145/980159.980173 被引量: 416 年份: 2004 ...
