Detecting and Repairing Inter-system Bias Jumps with Satellite Clock Preprocessing

Remote Sensing, 2020
The key to performing successful multi-GNSS (Global Navigation Satellite System) precise point positioning is calibrating ISB (inter-system bias) in different systems. We can use the method of modeling to eliminate the ISB error.

Assessment of Different Stochastic Models for Inter-System Bias between GPS and BDS [PDF]

Remote Sensing, 2019
Inter-system bias (ISB) will affect accuracy and processing time in integrated precise point positioning (PPP), and ISB stochastic models will largely determine the quality of ISB estimation.

PPP-RTK and Inter-System Biases: The ISB Look-Up Table as a Means to Support Multi-System PPP-RTK [PDF]

Journal of Geodesy, 2016
PPP-RTK has the potential of benefiting enormously from the integration of multiple GNSS/RNSS systems. However, since unaccounted inter-system biases (ISBs) have a direct impact on the integer ambiguity resolution performance, the PPP-RTK network and ...

Inter-System Biases Solution Strategies in Multi-GNSS Kinematic Precise Point Positioning [PDF]

GPS Solutions, 2023
Estimating inter-system biases (ISBs) is important in multi-constellation Global Navigation Satellite System (GNSS) processing. The present study aims to evaluate and screen out an optimal estimation strategy of ISB for multi-GNSS kinematic precise point

Influence of Horizontal Intraoral Scan Bodies on the Trueness of Digital Impressions for Complete-Arch Prostheses on Four Implants: An In Vitro Evaluation. [PDF]

Clin Oral Implants Res
ABSTRACT Objective To assess the impact of horizontal intraoral scan bodies (H‐ISBs) on the trueness of complete‐arch digital impressions compared to vertical ISBs (V‐ISBs). To evaluate trueness among four intraoral scanners (IOS) and inter‐operator variability across different ISB × IOS combinations. Materials and Methods Digital impressions were made

Adaptive Diversification of the <i>Mstnb</i> Locus Drives Genomic Architecture of Growth in Thai Clariid Catfish. [PDF]

Evol Appl
ABSTRACT The production of clariid catfish in Thai aquaculture depends on culture of the native species (Clarias macrocephalus and C. batrachus) and introduced African catfish (C. gariepinus). Particularly, hybridization with C. gariepinus has improved productivity but raised significant conservation concerns.
