Fixing of Cycle Slips in Dual-Frequency GPS Phase Observables using Discrete Wavelet Transforms
The occurrence of cycle slips is a major limiting factor for achievement of sub-decimeter accuracy in positioning with GPS (Global Positioning System). In the past, several authors introduced a method based on different combinations of GPS data together with Kalman filter to solve the problem of the cycle slips. In this paper the same philosophy is used but with discrete wavelet transforms. For...
متن کاملReliability of GPS cycle slip and outlier detection
The theory and application of statistical quality control is well established in surveying and geodesy. In recent years it is also gaining momentum in applications of marine positioning. The set of quality control recommendations of the United Kingdom Offshore Operators’ Association (UKOOA) is a good example in this respect. Quality control is made up of various contributing factors, one of whi...
متن کاملFault Detection of Plain Circular Knitted Fabrics Using Wavelet Transform
Quality control of textile products is an important stage in textile industries. To this end, the conventional method in fault detection is human inspection. In the present work, Wavelet transform was applied on images of simple circular knitted fabrics to diagnose five regular defects. The results showed that the method applied was accurate and fast in addition to being capable of determining ...
متن کاملGPS Cycle Slip Detection and Correction at Measurement Level
Carrier phase measurements are much more precise than pseudorange measurements and can be used to achieve very accurate positioning solutions. However, carrier phase measurements require resolution of integer ambiguities before precise positioning can be achieved. The GPS receiver can keep track of the integer number of cycles as long as the receiver maintains lock to the satellite signal. Howe...
