Inter-system Bias: Stability and impact on multi-constellation positioning

2015 IEEE Metrology for Aerospace (MetroAeroSpace), 2015
Global Navigation Satellite Systems (GNSSs) operate using independent time scales. For this reason, the determination of inter-system time offsets is required to enable multi-constellation solution. In this paper, two different approaches for the determination of the inter-system bias are considered and their performance is evaluated using measurements

BDS–GPS inter-system bias of code observation and its preliminary analysis

GPS Solutions, 2017
Navigation applications will benefit significantly from the improved reliability, availability, and accuracy offered by combining BeiDou Navigation Satellite System (BDS) and Global Positioning System (GPS). In the BDS/GPS navigation data fusion model, the effect of inter-system bias (ISB) must be considered.

A single difference-based multi-GNSS inter-system model with consideration of inter-frequency bias and inter-system bias

Measurement Science and Technology, 2020
Abstract By calibrating the inter-system bias (ISB), an inter-system model can be achieved to improve the performance of multi-global navigation satellite system (GNSS) positioning. A number of studies were carried out to compose inter-system models among code division multiple access (CDMA) systems.

Maximum Ratio Principle-Based Estimation of Difference Inter-System Bias

Journal of Navigation, 2020
The tight combination model improves the positioning accuracy of the Global Navigation Satellite System (GNSS) in complex environments by increasing the redundancy of observation. However, the ambiguity cannot be calculated directly because of the correlation between it and the phase difference inter-system bias (DISB) in the model. This paper proposes

Accounting for Inter-System Bias in DGNSS Positioning with GPS/GLONASS/BDS/Galileo

Journal of Navigation, 2017
Code Differential Global Positioning System (DGPS) is widely used in satellite navigation and positioning because of its simple algorithm and preferable precision. Multi-Global Navigation Satellite System (GNSS) is expected to enhance the accuracy, reliability and availability of Differential GNSS (DGNSS) positioning.

A statistical characterization of the Galileo-to-GPS inter-system bias

Journal of Geodesy, 2016
Global navigation satellite system operates using independent time scales and thus inter-system time offsets have to be determined to enable multi-constellation navigation solutions. GPS/Galileo inter-system bias and drift are evaluated here using different types of receivers: two mass market and two professional receivers.

Feasibility of easy-to-implement methods to analyze systematic errors of multipath, differential code bias, and inter-system bias for low-cost receivers

GPS Solutions, 2021
The low-cost receiver with multi-frequency and multi-constellation Global Navigation Satellite System (GNSS) observations is becoming the mainstream in positioning and navigation. It is crucial to estimate systematic errors, including the multipath, differential code bias (DCB), and inter-system bias (ISB) for such receivers.

Analysis and Modeling of the Inter-system Bias Between BDS-2 and BDS-3

2020
The BDS-3 system has provided positioning navigation and timing (PNT) service since December 2018, while applications show that there is inter-system bias (ISB) between the BDS-2 and BDS-3 systems. Origin of the ISB and its influences on Beidou positioning are analyzed, and then the positioning algorithm including ISB is presented in order to improve ...

Clustering and look-up table calibration of receiver inter-system bias for QZSS and GPS integration

Measurement Science and Technology, 2020
Abstract The Quasi-Zenith Satellite System (QZSS) from Japan will supplement the global positioning system (GPS) for more accurate and stable positioning, navigation and timing services. However, QZSS and GPS measurements are not free of inter-system bias (ISB) for various receiver brands.
