Analysis of Single Frequency, Carrier Phase Based GPS Positioning Performance and Sensor Aiding Requirements
The work described in this report outlines the design and testing of a low-cost, single frequency, carrier phase positioning system. Furthermore, aiding sensor accuracy requirements are analyzed to improve the robustness of the carrier phase system after emerging from signal outages. The applications of interest are ones with safety-of-life implications such as driver assist systems. The conten...
متن کاملReliable Carrier Phase Positioning
Preface Currently, the Global Navigation Satellite Systems (GNSS) GPS and GLONASS are modernized and new GNSS such as Galileo and Compass are developed. The modernization of GPS includes an additional signal on L5 which lies in an aeronautical band. This will enable a dual frequency positioning on board an aircraft and an elimination of the dispersive ionospheric delay, which is one of the larg...
متن کاملIntegrated use of GPS and EGNOS Carrier Phase Observations for High Precision Kinematic Positioning
Real-time satellite positioning at the sub-decimeter or even sub-centimeter level of accuracy requires the use of carrier phase data. However, in harsh operational environments such as those encountered in engineering environments, often the number and geometry of available satellites are insufficient, due to signal blockage. Combined use of GPS dual frequency and EGNOS single frequency carrier...
متن کاملLeast Squares Techniques for GPS Receivers Positioning Filter using Pseudo-range and Carrier Phase Measurements
In present study, using Least Squares (LS) method, we determine the position smoothing in GPS single-frequency receiver by means of pseudo-range and carrier phase measurements. The application of pseudo-range or carrier phase measurements in GPS receiver positioning separately can lead to defects. By means of pseudo-range data, we have position with less precision and more distortion. By use of...
متن کاملGeneric nanomaterial positioning by carrier and stationary phase design.
A generic approach for deploying various types of synthetic nanomaterials, including single-walled carbon nanotubes and nanoparticles, at well-defined locations on substrates is presented. The assembly is achieved through the complementary design of the stationary and carrier phases and utilizes the dewetting process during which polymer-encapsulated nanomaterials are delivered and positioned o...
