Practical Signal Quality Monitoring for Augmentation Systems
نویسندگان
چکیده
Signal Quality Monitoring (SQM) algorithms propose to detect anomalous GPS signal distortions primarily through the use of multicorrelator SQM receivers. However, currently no augmentation systems (e.g., WAAS or LAAS) have true, real-time SQM capabilities. Still, these systems introduce complexities such as multiple-receiver processing, stringent detection requirements, and potential hardware failures.

Damage detection and structural health monitoring of ST-37 plate using smart materials and signal processing by artificial neural networks
Structural health monitoring (SHM) systems operate online and test different materials using ultrasonic guided waves and piezoelectric smart materials. These systems are permanently installed on the structures and display information on the monitor screen. The user informs the engineers of the existing damage after observing signal loss which appears after damage is caused. In this paper health...
متن کاملSelf-Starting Control Chart and Post Signal Diagnostics for Monitoring Project Earned Value Management Indices
Earned value management (EVM) is a well-known approach in a project control system which uses some indices to track schedule and cost performance of a project. In this paper, a new statistical framework based on self-starting monitoring and change point estimation is proposed to monitor correlated EVM indices which are usually auto-correlated over time and non-normally distributed. Also, a new ...
متن کاملA Wireless Electronic Esophageal Stethoscope for Continuous Monitoring of Cardiovascular and Respiratory Systems during Anaesthesia
Background: The basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. Esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung sound due to existence of various noises in operating rooms. In addition, the stethoscope is not applicable for continues monitoring, and it is u...
متن کاملTransient Performance Analysis of a Multicorrelator Signal Quality Monitor
The ability to monitor and detect problematic distortions in the received GPS-SPS signal is a task of critical importance. Detection of these satellite signal anomalies or “evil waveforms” (EWFs) can be accomp lished using detailed monitoring of the correlation peak. Using the proposed “2-Order Step” (2OS) Threat Model for evil waveforms, previous analysis has shown that, in steady state, monit...

Strain gage mounted on the surface of the shafts with specified directions are one of the common methods for measurement of the torsion in shafts. The most critical problem in utilization of this method, particularly in the online monitoring of torsional vibration and instantaneous torque in rotary systems, is due to its signal transfer process. In this paper, a simple, practical and feasible m...
