Reliable 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 کاملGNSS Carrier Phase-Based Attitude Determination
The GNSS (Global Navigation Satellite Systems) are a valid aid in support of the aeronautic science. GNSS technology has been successfully implemented in aircraft design, in order to provide accurate position, velocity and heading estimations. Although it does not yet comply with aviation integrity requirements, GNSS-based aircraft navigation is one of the alternative means to traditional dead-...
متن کاملAnalysis 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 کاملTightly-Coupled Integration of Multi-GNSS Single-Frequency RTK and MEMS-IMU for Enhanced Positioning Performance
Dual-frequency Global Positioning System (GPS) Real-time Kinematics (RTK) has been proven in the past few years to be a reliable and efficient technique to obtain high accuracy positioning. However, there are still challenges for GPS single-frequency RTK, such as low reliability and ambiguity resolution (AR) success rate, especially in kinematic environments. Recently, multi-Global Navigation S...
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...
