(MHSS)Advanced Receiver Autonomous Integrity Monitoring(ARAIM)algorithm,this paper discusses the feasibility of the pseudorange-based baseline ARAIM method on the single-epoch PPP based on Real-Time Kinematic(RTK)networks(PPP-RTK)framework to overcome these difculties.In addition,a new scheme is ...
integrity monitoring at the user level that includes RAIM for multiple frequency multiple constellation (MFMC). The special focus will be on integrity monitoring for timing and high accuracy positioning such as PPP and NRTK, and integration with other sensors. innovative critical applications requiring...
by combining PPP and RTK, PPP-RTK can achieve fast convergence (Li et al.,2022a,b). It was confirmed that attributed to the reduction of the multipath effect, the application of a survey-grade antenna instead of the patch one can
Autonomous vehicles require a real-time positioning system with in-lane accuracy. They also require an autonomous onboard integrity monitoring (IM) technique to verify the estimated positions at a pre-defined probability. This can be computationally demanding. PPP-RTK is a promising positioning ...
Real-time integrity monitoring (IM) is essential for autonomous vehicle positioning, requiring high availability and manageable computational load. This research proposes using precise point positioning real-time kinematic (PPP-RTK) as the positioning method, combined with an improved classifi...

2018) and greater satellite velocities, which reduce the precise point positioning (PPP) convergence time (Ge et al. 2018). As one of the conditions for LEO-aided positioning, the precise orbits of the LEO satellites are essential information. Integrity monitoring (IM) in the near-real-time ...
Since PPP-RTK is usually implemented using a Kalman filter (KF), the well-known integrity monitoring schemes developed for least-squares-based systems cannot be directly applied to PPP-RTK. After considering the time-sequential nature of KF, we propose a user-end integrity monitoring scheme of ...
Integrity monitoringInteger ambiguity resolutionProtection levelThe precise point positioning (PPP)-based real-time-kinematic (RTK) method attracts increasing attention from both aca- demia and industry because of its potential for high accuracy positioning with a shorter convergence time compared to the ...
With the improvement of GNSS infrastructures and the growing demands for precise positions, high-precision positioning technologies such as Precise Point Positioning (PPP), Real-Time Kinematic (RTK), and PPP-RTK have been well developed. Meanwhile, the integrity monitoring upon these high-precision ...
