“…Sub-daily pole and nutation motions are corrected according to the IERS conventions (McCarthy and Petit, 2004). Lastly, for all of the PPP daily solutions the carrier phase ambiguities were not fixed to integers, but kept as float, and the cycle slip detection method implemented follows Liu (2011).…”

Abstract:The aim of this paper is to look into the achievable repeatability and accuracy from Precise Point Positioning (PPP) daily solutions when using GPS only (PPP GPS), GLONASS only (PPP GLO), and GPS plus GLONASS (PPP GPS+GLO) for static positioning. As part of the assessment, a comparison with global double difference (DD) GPS daily solutions is presented. It is shown, therefore, that all of the PPP daily solutions can achieve millimetric level repeatability, similar to the global DD GPS solutions. Furthermore, the mean of the biases between the PPP daily solutions and the global DD GPS daily solutions are constellation type dependent, while an improvement is found in the vertical component for PPP GPS+GLO over PPP GLO, as the latter may be more affected by any imperfections in the models for GLONASS antenna phase centre variations. It is concluded that PPP GLO daily solutions have the ability to be used as independent solutions to PPP GPS daily solutions for static positioning, and as an alternative to PPP GPS+GLO or global DD GPS daily solutions.

“…Additionally, the method can be complemented with the TEC and its rate (TECR, mathematically defined by TEC′ ) as proposed by Liu (2010). If the TEC estimated at epoch ( k ) is differentiated with that of epoch ( 1 k − ), the TECR can be computed using the backward difference operator as:…”

“…The differential phase of time method requires polynomial fittings to interpolate or extrapolate the data at the check epoch (XU, 2007). However, tests performed by Liu (2010) indicate that the polynomial cannot guarantee success all the time, particularly, when the size of the cycle-slip is small. Further, the Doppler integration method, like phase-code comparison, fails to detect small cycle-slips (LIU, 2010).…”

“…The basic assumption of this method is that the original signal is smooth and discontinuities (i.e., the cycle-slip) can be reasonably modelled by a multiple polynomial regression (DE LACY et al, 2008). However, Liu (2010) pointed out that this assumption may be valid in most cases; however, it is not valid when the GPS data are observed under high level ionospheric activities. Additionally, Zhang et al (2012) proposed a new approach for single frequent cycle-slip detection based on an autoregressive model by exploiting modern Bayesian statistical theory.…”

In this work, we assessed the performance of the cycle-slip detection methods: Turbo Edit (TE), Melbourne-Wübbena wide-lane ambiguity (MWWL) and forward and backward moving window averaging (FBMWA). The TE and MWWL methods were combined with ionospheric total electron content rate (TECR), and the FBMWA with second-order time-difference phase ionosphere residual (STPIR) and TECR. Under different scenarios, 10 Global Positioning System (GPS) datasets were used to assess the performance of the methods for cycle-slip detection. The MWWL-TECR delivered the best performance in detecting cycle-slips for 1 s data. The relative comparisons show that the FBMWA-TECR method performed slightly Author to whom correspondence should be addressed.

[1] This paper presents statistical analysis of arctic auroral oval ionospheric scintillation events during the current solar maximum based on high-rate Global Positioning System data collected in Gakona, Alaska (62.39°N, 145.15°W) from August 2010 to March 2013. The objective is to gain a better understanding of the climatology and morphology of ionospheric scintillation in high-latitude regions. A scintillation event filter, multipath identification procedures, and other processes are applied to exclude nonscintillation related signal intensity and phase fluctuation and to extract scintillation events with S 4 index above 0.12 and phase sigma above 6°from over 657 days of data. A total of over 5800 scintillation events were identified; most of them show phase fluctuations, only 10% of the phase fluctuations are accompanied by weak amplitude scintillation. Based on the occurrence time, signal direction of arrival, intensity, and duration of these scintillation events and the solar and geomagnetic activities associated with these events, diurnal, seasonal, spatial, and solar activity dependencies are derived and presented in the paper.
