Assessment of code bias variations of BDS triple-frequency signals and their impacts on ambiguity resolution for long baselines [PDF]
, 2016 Carrier phase ambiguity resolution over long\ud baselines is challenging in BDS data processing. This is\ud partially due to the variations of the hardware biases in\ud BDS code signals and its dependence on elevation angles.\ud We present an assessment ...

Improved HLLL Lattice Basis Reduction Algorithm to Solve GNSS Integer Ambiguity
International Journal of Aerospace Engineering, 2023 Recently, lattice theory has been widely used for integer ambiguity resolution in the Global Navigation Satellite System (GNSS). When using lattice theory to deal with integer ambiguity, we need to reduce the correlation between lattice bases to ensure ...

A Review of GNSS Carrier Phase Ambiguity Resolution and Conceptual AI-Driven Approaches
Engineering Proceedings, 2023 Precise Point Positioning (PPP) with Integer Ambiguity Resolution (IAR) is an effective way of improving the overall performance of the PPP technique both in terms of convergence time and accuracy. Even though PPP-IAR has seen a tremendous development in

Advanced Intelligent Systems, EarlyView.An agentic AI‐driven decision‐support framework for prosumers is proposed, integrating PV generation, load profiling, and multihorizon optimization within a four‐agent architecture. The approach significantly reduces grid dependence, enhances self‐sufficiency and prevents system oversizing.

Extended GNSS ambiguity resolution models with regularization criterion and constraints [PDF]
, 2009 This paper firstly presents an extended ambiguity resolution model that deals with an ill-posed problem and constraints among the estimated parameters. In the extended model, the regularization criterion is used instead of the traditional least squares ...

American Journal of Botany, EarlyView.Abstract Premise The identity of sterile floral organs in second‐whorl, alternisepalous positions within Caryophyllaceae remains contentious, having been described as staminodes, “petaloids,” or petals homologous with those of other Pentapetalae. Limited ingroup and outgroup sampling and floral developmental data and inadequate phylogenetic comparative

The impact of new signals on precise marine navigation - initial results from an experiment in Harwich Harbour [PDF]
, 2008 The General Lighthouse Authorities of the United Kingdom and Ireland (GLAs) are supporting a project at University College London (UCL) to study whether it is possible to meet the International Maritime Organisation’s (IMO) future requirements for port ...

Single Epoch Ambiguity Resolution of Small-Scale CORS with Multi-Frequency GNSS
Remote Sensing, 2021 The network real-time kinematic (RTK) technique uses continuously operating reference stations (CORS) within a geographic area to model the distance dependent errors, allowing users in the area to solve ambiguities.

Modeling and parameter estimation for fractional large‐scale interconnected Hammerstein systems
Asian Journal of Control, EarlyView.Abstract This paper addresses the challenge of modeling and identifying large‐scale interconnected systems exhibiting memory effects, hereditary properties, and non‐local interactions. We propose a fractional‐order extension of the Hammerstein architecture that incorporates Grünwald–Letnikov operators to capture complex dynamics through multiple ...
