Explanation of the curves
Black are tle's from Kelso's Celestrak web site
Blue are tle's from SPAWAR
Red are the tle's used for
monitoring spacecraft orbit and attitude. ("QA" in the plot legend
refers to quality assured, as well as we can do it..)
Results: 24 hour average longitude and drift rate computed for each
QA'ed tle.
Note: spikes are (potential) lunar eclipses; Sonopaq has a bug determining
longitude/drift rate when it detects a lunar eclipse.
