Ionospheric Regions Producing Anomalous GNSS Radio Occultation Results
IEEE Transactions on Geoscience and Remote Sensing, 2018Anomalous GPS radio occultation (RO) events are characterised as those with L1 bending angle greater than their corresponding L2 bending angle. An investigation by EUMETSAT and the United Kingdom Meteorological Office revealed there are regions in the earth’s atmosphere where at times up to 60% of Global Navigation Satellite System Receiver for ...

(Near-)real-time orbit determination for GNSS radio occultation processing
GPS Solutions, 2012The processing of GPS radio occultation measurements for use in numerical weather predictions requires a precise orbit determination (POD) of the host satellite in near-real-time. Making use of data from the GRAS instrument on Metop-A, the performance of different GPS ephemeris products and processing concepts for near-real-time and real-time POD is ...

Developments of GNSS Radio Occultation for Sounding Atmosphere
2009 International Conference on Environmental Science and Information Application Technology, 2009Compared to traditional radiosonde and radar probing, the Global Navigation Satellite System radio occultation (GNSS RO) is a powerful tool for atmospheric sounding, which have many traits such as no calibration, all-weather, almost uniform global coverage, high precision and vertical resolution. In this paper, investigative actuality which we make use

On constellation design of multi-GNSS radio occultation mission
Acta Astronautica, 2013Abstract The FORMOSAT-3/COSMIC mission which is a joint Taiwan-US mission for meteorological, climatological, ionospheric, and geodetic studies has successfully provided a significant amount of GPS radio occultation (RO) data for better modeling of climate model, forecasting of weather, and monitoring of ionosphere.

Improvements in Geodetic Surveying Using GNSS Radio Occultation Observations
2017The coordinates of a static Global Navigation Satellite System (GNSS) station placed on the ground are estimated together with the delay suffered by the incoming satellite signals through the atmosphere. The tropospheric delay (TD) is shaped as the product of the zenith total delay (ZTD) times a slant factor or mapping function (MF) depending on the ...

GNSS Radio Occultation from LEO: Occultation Management and Open-loop Tracking Aspects
2004This paper focuses on particular aspects of customised GPS receivers for radio occultation: occultation management and open-loop tracking. The two aspects are closely related because open-loop tracking requires a-priori geometric information about the occultation events.
