Empirical once per revolution along-track accelerations were adjusted daily for these arcs, in addition to a drag coefficient per day, a reflectivity coefficient per arc, and the empirical accelerations for the AMD events. March 1999 is a particularly tough test for the crossovers since the Doppler data - although sparse, are of high quality. In addition, the Doppler data in March 1999 were used in the MGM0964C20 solution. The average RMS overlap is shown in Table 8 for the three overlaps of these arcs. The addition of the crossover data improves the orbits overall, and especially in the radial, and the along-track directions.
Some degradation is observed in the cross-track direction.
It is especially encouraging that the consistency in the radial direction has been further improved from 0.59 to 0.26 meters.
