Integrating Optic Flow, Ins and Gps Time Differenced Carrier Phase Measurements for Uav Surveying and Mapping
To improve the performance of UAV navigation and geo-referencing systems, this work has proposed an approach of integrating optic flow, INS and GPS time differenced phase measurements. Time-differenced carrier phase measurement (TDCP) is used to estimate the precise position changes (delta positions) of the GPS receiver between observation epochs, which then constitutes a precise aiding source ...
متن کاملOn-the-fly GPS-based attitude determination using single- and double- differenced carrier phase measurements
Carrier phase measurements are primary observations for GPS attitude determination. Although the satelliterelated errors can be virtually eliminated by forming single differences, the baseline-related errors, such as line biases, are still present in the single-differenced carrier phase measurements. It is, therefore, difficult to resolve the single-differenced integer ambiguities due to the li...
متن کاملA Hybrid Carrier Phase Measurement Weighting Scheme for Solution Improvement of Carrier Point Positioning
Operation of GNSS receivers in noiseand interferencedominated environments results in degraded solution accuracy and precision. Locata, working on similar principles to the Global Positioning System (GPS) and using single point carrier phase positioning, can suffer from similar issues. This paper considers a variety of schemes to address these problems. It is established, using simulation resul...

15 صفحه اولA Study of GPS Carrier-Phase Time Transfer Noise Based on NIST GPS Receivers
To do a better time comparison between high-precision clocks (such as a Cesium-fountain clock and Hydrogen-maser clock), we want to study and eventually lower the GPS carrier-phase time transfer noise. The GPS carrier-phase time transfer noise comes from four sources: GPS satellite, GPS signal path, ground receiving equipment (receiver and antenna), and data-processing algorithm. This paper foc...
