Fig. 9From: Study on systematic errors of BDS-3 broadcast ephemeris and their effects with Helmert transformationCorrelations of rotation parameters among different orbital planes. The subgraphs show the correlations of the x-rotation between orbit planes A and B (a), B and C (d), and C and A (g); the correlations of the y-rotation between orbit planes A and B (b), B and C (e), and C and A (h); and the correlations of the z-rotation between orbit planes A and B (c), B and C (f), and C and A (i)Back to article page
