The Effect of Cross-Correlation Items on the Intersystem Interference Between GPS, BDS and Galileofective carrier power-to-noise density ratio (.) and its degradation are important criteria to evaluate the degree of interference between Global Navigation Satellite Systems (GNSS). In order to simplify the analysis process and computational complexity, the cross-correlation items between desired s

An Implementation of Navigation Message Authentication with Reserved Bits for Civil BDS Anti-Spoofinions of NMA may cause a failure in legacy GNSS receiver to process civil GNSS signal. This paper proposes an implementation of NMA applying reserved bits as signature area. Digital signature and key chain algorithms are employed to improve security and efficiency of the implement. In additional, per

An Efficient Algorithm for Determining the Correspondence Between DFREI and σDFRE for a Dual-Frequen system (SBAS) providers are currently developing the dual-frequency multi-constellation (DFMC) SBAS interface control document (ICD) to take advantage of the four GNSSs and two signals. In order to ensure the interoperability, a SBAS provider is allowed to determine the correspondence between DFREI

Analysis on Ionospheric Delay Variogram Modeling in Chinaompared for various solar activity conditions and different latitudes for China and around areas. It shows that the ionospheric anomaly in low-latitude areas impacts the variogram seriously, causing a larger intercept at zero distance and a “bump” at the distance of about 1000 km. An alternative met

Scintillation Modeling and Its Application in GNSSd signal propagating model. Irregularity strength model describes the spatial and temporal variation of strength of scintillation-producing irregularities. The model could be represented in terms of solar activity, magnetic latitudes, season and local time, and the coefficients are derived with meas

A New Algorithm for Receiver Integrity Monitoring with Receiver Clock Error Auxiliaryomous integrity monitoring (RAIM) and auxiliary autonomous integrity monitoring. Apart from the redundant observations of the receiver are used for RAIM, there are various parameter information provided form receiver and the receiver clock error is one of them. As the stability of the receiver oscil
