“…For the integrity monitoring of carrier-phase data, various studies can already be found in the literature. For dual-frequency GPS data, for instance, methods of carrier phase-slip detection are discussed and tested in (Lipp and Gu 1994;Mertikas and Rizos 1997;Blewitt 1998;Teunissen 1998a;Gao and Li 1999;Jonkman and de Jong 2000;Bisnath and Langley 2000;Bisnath et al 2001;Liu 2010;Miao et al 2011). More recent studies on triple-frequency carrier phase-slip detection can be found in (Fan et al 2006;Dai et al 2009;Wu et al 2010;De Lacy et al 2011;Xu and Kou 2011;Fan et al 2011).…”

In this contribution the integrity of singlereceiver, single-channel, multi-frequency GNSS models is studied. The uniformly most powerful invariant test statistics for spikes and slips are derived and their detection capabilities are described by means of minimal detectable biases (MDBs). Analytical closed-form expressions of the phase-slip, code-outlier and ionospheric-disturbance MDBs are given, thus providing insight into the various factors that contribute to the detection capabilities of the various test statistics. This is also done for the phaseless and codeless cases, as well as for the case of a temporary loss-of-lock on all frequencies. The analytical analysis presented is supported by means of numerical results.

“…In the GNSS measurement observation, the Doppler counter's whole-week count is temporarily interrupted, and the part of the carrier phase observation with system deviation and less than one full week remains the correct phenomenon, called the cycle slip (Miao, Y., 2011). The cycle slip ratio is a method of statistics by observing the proportion of observable data in weekly epochsz (Tian, Q., 2017).…”

Abstract. Aiming at the observation data of CORS multi-mode data quality and inspection in CORS station, based on the observation data of a CORS station in Guilin, Guangxi, the paper used TEQC and Anubis software to check the data quality from data utilization, cycle slip ratio and multipath. The results show that the three quality inspection indicators of Anubis software are better than TEQC software, which proves that Anubis' data quality inspection results are effective and reliable. On this basis, using Anubis drawing tools to perform quality inspection and visual analysis from satellite constellation, signal band and observation data itself, it shows that Anubis' visual content is more elaborate than TEQC, and users can more intuitively understand and control the data quality of CORS station.

“…In integration of the ionospheric total electron contents rate and Melbourne-Wübbena (MW) linear combination, one algorithm was proposed to uniquely identify the cycle slip on both L1 and L2 frequencies (Liu, 2011). A weighted factor which is tightly related to the GPS satellite elevation angle was introduced in the cycle slip identification process and a modified TurboEdit algorithm (Blewitt, 1990) was proposed (Miao et al, 2010). A Forward and Backward Moving Window Averaging (FBMWA) scheme and a Second-order, Time-difference Phase Ionospheric Residual (STPIR) scheme were integrated to jointly detect and identify cycle slip (Cai et al, 2013).…”

The integration of Precise Point Positioning (PPP) with Inertial Navigation Systems (INS) has been very intensively developed and widely applied in multiple areas. The integrated navigation system is able to provide high accuracy position and attitude with a single receiver. However, the cycle slip caused by high dynamics, signal lock and low satellite elevation will decrease accuracy and degrade the system performance. In this paper, an inertial aided cycle slip detection and repair method is applied in PPP/INS tightly coupled navigation to obtain higher accuracy navigation information. The inertial information is introduced to the wide-lane combination observation to avoid the noise and multipath from pseudorange. Detail error analysis is given to determine the critical value of INS position accuracy which makes inertial aided wide-lane combination have better performance and a new decision variable is constructed. The inertial aided cycle slip detection and repair scheme that replaces the ambiguity re-initialisation is applied in PPP. An experiment was performed to validate the new algorithm. The results indicate that the inertial aided decision variable has higher accuracy than the traditional Melbourne-Wübbena decision variable. The inertial aided scheme can efficiently detect and repair the small cycle slip (from 1 to 6) and large cycle slip (from 10 to 20). The inertial-aided cycle slip detection method introduced in PPP resolution will remove the error by ambiguity re-initialisation.
