The Effect of the Subdaily Periodic Signal on the Long Period Term of GNSS Coordinate Time Series
Abstract The influence of the subdaily signal represented by the multipath on the characteristics of the short baseline time series is evaluated in this paper. Results show that multipath will introduce spurious signals for a long period with amplitude 0.1~0.3 mm in the height direction, but little in the plane direction. Unmodeled elevation-dependent subdaily signals will introduce spurious long period signals to the daily coordinate time series in the direct component, but the spurious amplitude can be decreased by increasing the cutoff of elevation properly.
