Robust Modeling of GNSS Orbit and Clock Error Dynamics

open access: yesNavigation, 2022
In this paper, we develop new stochastic orbit and clock error models for positioning, fault detection, and integrity monitoring over time. GPS and Galileo orbit and clock data are evaluated and ranging errors are analyzed and modeled over time.

A state-domain robust autonomous integrity monitoring with an extrapolation method for single receiver positioning in the presence of slowly growing fault

open access: yesSatellite Navigation, 2023
Single receiver positioning has been widely used as a standard and standalone positioning technique for about 25 years. To detect the slowly growing faults caused by satellite and receiver clocks in single receiver positioning, the Autonomous Integrity ...

RAIM Fault Detection and Exclusion with Spatial Correlation for Integrity Monitoring

open access: yesRemote Sensing, 2022
For safety-of-life applications used together with global navigation satellite systems, such as in civil aviation and autonomous driving, integrity is of paramount importance. Integrity monitoring protects the user safety based on two general approaches:

T-RAIM Approaches: Testing with Galileo Measurements

open access: yesSensors, 2023
Several applications rely on time retrieved from Global Navigation Satellite System (GNSS), and this pushes for integrity tailored to timing. Integrity information could be broadcast by GNSS itself, but currently, there are no GNSSs providing such ...

ARAIM Stochastic Model Refinements for GNSS Positioning Applications in Support of Critical Vehicle Applications

open access: yesSensors, 2022
Integrity monitoring (IM) is essential if GNSS positioning technologies are to be fully trusted by future intelligent transport systems. A tighter and conservative stochastic model can shrink protection levels in the position domain and therefore enhance
