This paper analyzes the effect of error correlation on the SISRE bounding for GPS and
Galileo satellites. For a given period of data collection, it computes the effective number of …

As its name implies, ARAIM is an evolution of Receiver Autonomous Integrity Monitoring
(RAIM) which has been used by aircraft for many years to support horizontal navigation [1, 2 …

This paper presents a URA/SISA analysis to support ARAIM based on a time-dependent
statistical characterization of orbit and clock errors observations. For each individual GPS …

In this paper, we derive new satellite orbit and clock error models for time sequential, dual
frequency, multi-constellation Advanced Receiver Autonomous Integrity Monitoring (ARAIM) …

This paper presents a User Range Accuracy (URA)/Signal‐in‐Space Accuracy (SISA)
analysis to support ARAIM based on a time‐dependent statistical characterization of orbit …

With more than 70 navigation satellites orbiting the Earth, global navigation satellite systems
(GNSS) users are fascinated to use multiple constellations to enhance positioning …

The largest source of error uncertainty in current Space-based Augmentation Systems,
which are single frequency (L1), is the ionospheric delay. In the coming years, the …

The modernization of current GNSS services such as GPS, and the development and
deployment of new constellations, such as Galileo, allow for new concepts as ARAIM to be …

Time synchronization is one of the main applications of Global Navigation Satellite System
(GNSS). Indeed, GNSS satellites are equipped with highly stable atomic clocks, which can …

The Advanced Receiver Autonomous Integrity Monitoring (ARAIM) concept requires a
conservative characterization of the nominal pseudorange error bounds. This paper …
