Effect of the GPS fixed weights on the degree difference variance (DDV) of the laser ranging interferometer (LRI) solutions at mid and high degrees (20–60). Results are shown for the test case of July 2019. The K/Ka‐band ranging (KBR) DDV (red) and the DDV for the LRI solution (green) estimated with the same weighting strategy as the KBR solution are also plotted for comparison. The GPS weights are fixed to (a) 2 times the a priori weights to 10 times the a priori weights, then (b) 20 times the a priori weights, and finally (c) 30 times the a priori weights to 50 times the a priori weights.
