Wilfried De Backer,Jan Verhaertty risk of signal in space. Firstly, the original data should be preprocessed to calculate measured signal-in-space error. Secondly, the regularity of the errors is estimated by the spectrogram, followed by fitting orbit error with the least squares method based on Fourier series and AR model and fi薄荷醇 发表于 2025-3-30 15:06:24

Simulation results show that the selection of PN codes for data component may cause correlation function asymmetry. In order to reduce the effect on single sideband reception and reach the same performance with AltBOC(15,10), the selection of PN codes hMorose 发表于 2025-3-30 18:27:05

The simulation results of the measured data of different type in-orbit satellite which is from 2002 to 2011 show that the abnormal rate of signal in space is 10./h, which meet the index that three satellites may fault every year, therefore the analysis m强制性 发表于 2025-3-31 07:15:32

Research on GNSS Interoperability Parametersis set is defined as interoperability parameter. The interoperability parameters can be separated into signal level and message level, and should be broadcast to users in a common time reference and coordinate reference frame. Then, we discussed the definition, detection and calculation method of ea骂人有污点 发表于 2025-3-31 21:59:42
GNSS Satellite Selection Algorithm Revisited: A Weighted Way with Integrity Considerationn. Giving the fact that the loss of some satellite may have little difference on the DOP, but could impose a negative influence on the integrity performance, satellite selection should therefore give an insight into the selection criterion and the determination of the threshold values. A novel satel
