Abstract The High Accuracy Service (HAS) is an upcoming addition to the Galileo service portfolio that offers free correction data for precise point positioning in real-time. Beyond terrestrial and aeronautical applications, orbit determination (POD) of satellites low Earth (LEO) has been proposed as a potential use case HAS corrections view their global availability. Based on collected during test campaign September 2021, benefit assessed real-time, onboard navigation well near real-time...
Abstract Precise point positioning (PPP) and real-time kinematic techniques are interesting in several sectors, especially for autonomous applications. These users have high accuracy needs coupled with stringent requirements on continuity, availability, integrity, convergence time, whose satisfaction can be challenging harsh environments. Galileo launched January 2023 the initial service (HAS), a European free-of-charge PPP worldwide coverage transmitted E6 signals provided through an...
Integrating satellite based navigation into the railway standard can enable reliable and cost-efficient everywhere. This makes is very attractive for railway. Thus its integration strongly supported within European evolution program. However, environments exhibit many challenges. Local threats are major issues robust GNSS navigation. They cannot be observed by any augmentation methods cause hazardous misleading information. Hence, they form an integrity risk, which needs to detected...
Autonomous transportation requires high accuracy positioning and, when the receiver is in safety critical operations, solution needs to be robust external threats and reliable from an integrity point of view (i.e. internal threats). Precise Point Positioning (PPP) services may not only satisfy demanding but beneficial also for applications: using fast corrections increase help detect or mitigate effects satellite faults. Even if PPP message does include information, a developing autonomous...
With the new upcoming GNSS constellation in future it might no longer be possible to use all satellites view for navigation due limited tracking channels. This is particular true context of Advanced Receiver Autonomous Integrity Monitoring (ARAIM), where dual frequency favorable mitigate ionospheric disturbances. To address issues channels we propose two different selection strategies adapted Horizontal ARAIM this paper. First a bare geometric approach which comes with almost additional...
Diabetes is an increasing global health burden with the highest prevalence (24.0%) observed in elderly people. Older diabetic adults have a greater risk of hospitalization and several geriatric syndromes than older nondiabetic adults. For these conditions, special care required prescribing therapies including anti- diabetes drugs. Aim this study was to evaluate appropriateness adherence safety recommendations prescriptions glucose-lowering drugs hospitalized patients diabetes. Data for...
Within the next future, advent of Galileo, GPS modernization and GNSS augmentation systems, will lead to a rapid development receiver technologies. It is expected that improved accuracy performance extend use satellite positioning navigation applications where present systems do not fulfill user integrity requirements allow certification. In this scenario central role played by capability. fact large part users carrying out in which an error might represent excessive risk, particular when...
In this paper, we describe assumptions and assertions needed to account for continuity availability risks in Advance Receiver Autonomous Integrity Monitoring (ARAIM). We identify key differences with current RAIM-based operations, including the potential of ARAIM not require systematic pre-flight screening. The provide a rationale on why fault exclusion is horizontal-ARAIM (H-ARAIM), but vertical (V-ARAIM). implement existing methods design new approaches predict presence satellite faults...
Advanced Receiver Autonomous Integrity Monitoring (ARAIM) is a concept that extends today’s RAIM by incorporating dual frequency signals and multiple constellations [1], [2]. The potential benefits of Horizontal ARAIM have been well established, both through simulation ([1],[2],[3]), using flight data [4]. Looking further into the future, we expect implementing horizontal guidance will pave way for vertical guidance. As operations converges ([5], [6]), Dual Frequency Multi-Constellation SBAS...
The characterization of Galileo Open Service signal-in-space (SiS) represents an essential input to Safety-of-Life (SoL) applications like Horizontal ARAIM (Advanced Receiver Autonomous Integrity Monitoring) and SBAS (Satellite Based Augmentation System) in particular EGNOS V3.

Sepsis is a life-threatening syndrome with complex pathophysiology and great clinical heterogeneity which complicates the delivery of personalized therapies. Our goals were to demonstrate that some biomarkers identified as regulatory immune checkpoints in preclinical studies could 1)improve sepsis prognostication based on variables 2)guide stratification septic patients subgroups shared characteristics response or survival outcomes.
