An Algorithm for Combined Code and Carrier Phase Based Gps Positioning∗
The Global Positioning System (GPS) is a satellite based navigation system. GPS satellites transmit signals that allow one to quite accurately estimate the location of GPS receivers. In GPS a typical technique for kinematic position estimation is relative positioning where two receivers are used, one receiver is stationary and its exact position is known, the other is roving and its position is...
متن کاملAutomated cycle-slip correction of dual-frequency kinematic GPS data
In order to attain high precision positioning and navigation results with GPS, cycle slips must be correctly repaired at the data preprocessing stage. Over the past decade a number of methods have been developed to detect and repair cycle slips. These methods invariably require user intervention for problematic cycle slips in portions of data, tuning of input parameters to data, or introduction...
متن کاملFrequency syntonization using GPS carrier phase measurements
A new methodology of frequency syntonization using a global positioning system (GPS) carrier phase double differences is presented. The proposed scheme can achieve the traceability of frequency dissemination and obtain the very high frequency stability in the short term, as well as in the long term. The GPS receivers used in our system were elaborately modified in order to estimate the frequenc...
متن کاملBandwidth Optimization of Carrier/Code Tracking Loops in GPS Receiver
Global Navigation Satellite System (GNSS) is the standard generic term for satellite navigation systems that provide autonomous geospatial positioning with global coverage. As of 2007, the United States NAVSTAR Global Positioning System (GPS) is the only fully operational GNSS. Based on bandwidth optimization criterion, the GPS receiver is proposed for solving the carrier/code phase tracking pr...
متن کاملA Space-Frequency Block Code for Single- Carrier FDMA
A full-diversity space-frequency block code (SFBC) for Single-Carrier Frequency-Division Multiple Access (SC-FDMA) systems is presented. The code is designed for 2 transmit antennas and preserves the low envelope fluctuations of SC signals. We prove the good performance of the proposed scheme over multiple-input multiple-output (MIMO) channels, both in static and in high-speed mobility scenarios.
