Ionospheric 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 کاملImproving the Reliability of GPS and GLONASS Navigation Solution in Urban Canyons using a Tuned Kalman Filter
Abstract: Urban canyon is categorized as hard environment for positioning of a dynamic vehicle due to low number and also bad configuration of in-view satellites. In this paper, a tuning procedure is proposed to adjust the important factors in Kalman Filter (KF) using Genetic Algorithm (GA). The authors tested the algorithm on a dynamic vehicle in an urban canyon with hard condition and compare...

15 صفحه اولGlobal Ionospheric Modelling using Multi-GNSS: BeiDou, Galileo, GLONASS and GPS
The emergence of China's Beidou, Europe's Galileo and Russia's GLONASS satellites has multiplied the number of ionospheric piercing points (IPP) offered by GPS alone. This provides great opportunities for deriving precise global ionospheric maps (GIMs) with high resolution to improve positioning accuracy and ionospheric monitoring capabilities. In this paper, the GIM is developed based on multi...
متن کاملClock Synchronization Using Gps/glonass Carrier Phase
Clock synchronization by means of GPSIGLONASS is proposed. The GPSIGLONASS receivers with the external frequency input interface are used in our system. While the remote OCXO (OvenControlled Crystal Oscillator) clock and the primary H-maser clock are connected to the receivers, the frequency o s e t of the remote clock with respect to the primary clock can be estimated by performing the linear-...
