Statistical Characterization of GLONASS Broadcast Ephemeris Errors
For critical navigation applications such as aircraft approach and landing, there is a general desire to use multi-constellation global navigation satellite systems (GNSS) to enhance availability and reliability. The Russian Global Navigation Satellite System (GLONASS) is so far the only other constellation nearly as developed as the Global Positioning System (GPS). A thorough characterization ...
متن کاملStatistical Characterization of GLONASS Broadcast Clock Errors and Signal-In-Space Errors
With more than 70 navigation satellites around the Earth, global navigation satellite systems (GNSS) users are fascinated to use multiple constellations to enhance positioning availability, accuracy, integrity, continuity, and robustness. As the Russian Global’naya Navigatsionnaya Sputnikovaya Sistema (GLONASS) has fully restored its constellation, not only does a combination of GLONASS and the...
متن کاملIonospheric Modelling using GPS to Calibrate the MWA. II: Regional ionospheric modelling using GPS and GLONASS to estimate ionospheric gradients
We estimate spatial gradients in the ionosphere using the Global Positioning System (GPS) and GLONASS (Russian global navigation system) observations, utilising data from multiple GPS stations in the vicinity of Murchison Radio-astronomy Observatory (MRO). In previous work the ionosphere was characterised using a single-station to model the ionosphere as a single layer of fixed height and this ...
متن کاملEmpirical Characterization and Modeling of GPS Positioning Errors Due to Ionospheric Scintillation
Ionospheric scintillation degrades GPS positioning accuracy in a number of ways. Along each scintillating satellite-receiver link, errors are introduced in the measurements of pseudorange and carrier phase. When the scintillation on a given link is sufficiently intense, the link becomes intermittently unavailable for use in the position solution. The loss of each link leads to an increased dilu...
متن کاملGPS/GLONASS System Bias Estimation and Application in GPS/GLONASS Combined Positioning
Multi-GNSS data analysis has become a new challenge with the development of satellite navigation systems. System bias is the key issue in Multi-GNSS data analysis, which has no recommended models within IGS community. We introduce the integrated data analysis model developed at the GNSS data analysis center of Shanghai Astronomical Observatory (SHAO). Based on the routine GNSS data analysis at ...
