Gnss Tomography of the Atmosphere - Expectation from Galileo Foc
نویسندگان
چکیده
The aim of this paper is to investigate the impact of the upcoming Galileo system on GNSS tomography. The area covered by our tomography model is limited to the Austrian territory. The GPS and GLONASS data of 12 sites in different environments are analysed with respect to its quality and impact on the atmospheric tomography approach. We show how additional Galileo observations help to close the lack of data and therewith to improve the quality of the derived refractivity field. The Galileo constellation (26 satellites as planned to be active in 2015) is simulated by a signal generator which is able to provide Galileo E1 observations in RINEX format.

GNSS meteorology is the remote sensing of the atmosphere (particularly troposphere) using Global Navigation Satellite Systems (GNSS) to deliver information about its state. The two currently available navigation satellite systems are the Global Positioning System (GPS) and the GLObal’naya NAvigatsionnaya Sputnikovaya Sistema (GLONASS) maintained by the United States and Russia, respectively. Th...
متن کاملOn the Applicability of Galileo FOC Satellites with Incorrect Highly Eccentric Orbits: An Evaluation of Instantaneous Medium-Range Positioning
This study addresses the potential contribution of the first pair of Galileo FOC satellites sent into incorrect highly eccentric orbits for geodetic and surveying applications. We began with an analysis of the carrier to noise density ratio and the stochastic properties of GNSS measurements. The investigations revealed that the signal power of E14 & E18 satellites is higher than for regular Gal...

Benefits from the modernized US Global Positioning System (GPS), the revitalized Russian GLObal NAvigation Satellite System (GLONASS), and the newly-developed Chinese BeiDou Navigation Satellite System (BDS) and European Galileo, multi-constellation Global Navigation Satellite System (GNSS) has emerged as a powerful tool not only in positioning, navigation, and timing (PNT), but also in remote ...
متن کاملGNSS Inter-Constellation Phasing: Validation of the Worst Case Assumption
Advanced Receiver Autonomous Integrity Monitoring (ARAIM) uses satellite range measurements from multiple GNSS constellations to determine navigation integrity. Providing robustness against multiple simultaneous satellite faults, ARAIM needs a much higher number of available measurements than a classical RAIM [1]. Studies [2, 3, 18] expect that the performance of ARAIM based integrity will be s...
متن کاملGNSS Signals: A Powerful Source for Atmosphere and Earth’s Surface Monitoring
It is well known that Global Navigation Satellite Systems signals (which include for example the U.S. GPS and its modernization, the Russian GLONASS, the future European Galileo, the Chinese COMPASS), commonly processed for navigation purposes, can also be used to characterize media where they propagate in. In the last decade, GNSS atmospheric and Earth’s surface remote sensing become more and ...
