چکیده

This paper presents a new way of combining Abel inversion and the Chapman model with linearly increasing scale height to retrieve ionospheric electron density vertical profiles from truncated-sounding radio-occultation data. A linear Vary–Chap is used cover blind region due data truncation, parameters estimated by enumeration possible values in grid centered around set compatible physics. The resulting its corresponding error least-squares solution presenting smaller post-fit residual on input GNSS carrier-phase measurements. results, tested representative RO measurements obtained COSMIC/FORMOSAT-3, show that this method can EDVPs predominant absolute relative 1010e−m−3 5%, respectively, less than 10 s per profile, which makes suitable for near real-time applications upcoming missions such as EUMETSAT Polar System-Second Generation.

Ionospheric and plasmaspheric electron contents inferred from radio occultations and global ionospheric maps

We introduce a methodology to extract the separate contributions of the ionosphere and the plasmasphere to the vertical total electron content, without relying on a fixed altitude to perform that separation. The method combines two previously developed and tested techniques, namely, the retrieval of electron density profiles from radio occultations using an improved Abel inversion technique and...

Improvement of ionospheric electron density estimation with GPSMET occultations using Abel inversion and VTEC information

[1] As it is known, the Abel transform has been proven to be a useful tool that offers the possibility to obtain vertical description of ionospheric electron density (among other neutral atmosphere parameters) through inversion of Global Positioning System (GPS) observations gathered by Low Earth Orbiters (LEO). This work is focused on extending the application of this technique to GPSMET data ...

Real-time Kinematic Positioning of INS Tightly Aided Multi-GNSS Ionospheric Constrained PPP

Real-time Precise Point Positioning (PPP) technique is being widely applied for providing precise positioning services with the significant improvement on satellite precise products accuracy. With the rapid development of the multi-constellation Global Navigation Satellite Systems (multi-GNSS), currently, about 80 navigation satellites are operational in orbit. Obviously, PPP performance is dra...

GPS radio occultations

The occurrence of sporadic E (Es) layers has been a hot scientific topic for a long time. The GNSS (global navigation satellite system)-based radio occultation (RO) has proven to be a powerful technique for detecting the global Es layers. In this paper, we focus on some cases of complex Es layers based on the RO data from multiple missions processed in UCAR/CDAAC (University Corporation for Atm...

Real-Time Ionospheric Scintillation Monitoring

As the millennium approaches we are faced with a period of increasing solar flux and intense ionospheric scintillation. Not only single-frequency, but also dualfrequency GPS measurements will be badly affected by deep scintillation, due to its temporal and spatial decorrelation characteristics. Using the scintillation observables derived from dual-frequency phase and signal-to-noise ratio measu...
