From: Improving BDS broadcast ephemeris accuracy using ground-satellite-link observations
RMS values of daily SPP position errors at station KARR (Australia) in the north, east, and height component from Jan. 2016 to April 2021 using BDS broadcast ephemeris. Vertical grey lines mark the starting epochs when coordinate accuracy is apparently improved. The pink color illustrates the daily average number of tracked BDS satellites. The zoom-in subplot illustrates the mean positioning errors of each coordinate component during the four different periods
