GPS Multipath Change Detection in Permanent GPS Stations
A technique based on an adaptive filter using the least-mean-square algorithm is proposed for detection of multipath change in permanent, continuously operating GPS (CGPS) stations. The technique has been tested on some experimental data, indicating that the multipath change above the receiver noise level can be detected. Further tests have been conducted with some CGPS data from the Japanese G...
متن کاملDynamic Harmonic Analysis of Long Term over Voltages Based on Time Varying Fourier series in Extended Harmonic Domain
Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs an Extended Harmonic Domain (EHD) based framework for dynamic analysis of long term analysis over voltages during the tra...
متن کاملMultipath Mitigation of Permanent GPS Stations Using Wavelets
It is well known that multipath disturbance is one of the major error sources impacting on high precision GPS positioning. The multipath disturbance is largely dependent on the receiver’s environment since satellite signals can arrive at the receiver via multiple paths, due to reflections from nearby objects such as trees, buildings, vehicles, etc. Although the multipath effect can be reduced b...
متن کاملCarrier Phase Multipath Calibration of GPS Reference Stations
Based on available GPS reference network observations we developed, implemented and tested a procedure to estimate carrier phase multipath corrections. This procedure consists of three steps: detection and localization of multipath affected satellite signals, daily estimations of multipath errors, and combination of these daily estimates to corrections for undifferenced L1 and L2 phase measurem...
