My apologies for misunderstanding Gerhard's wording - I was only thinking that an elset ought to match the (latest) observations upon it was computed. Of course it is interesting to know if an elset based only on previous observations matches the recent ones. But that partly relies on making a good guess on (average) future drag, partly on matching models for analysis and prediction. Greg provided 9 points on 20060312 and Mike made this elset: Unknown 041206 1 90027U 04841A 06071.55035598 0.00001113 00000-0 11045+1 0 09 2 90027 62.3773 158.6750 6940454 268.4454 91.5512 2.00728666 05 I find the previous elset 100 days old, but no comment by Greg on how he found the satellite, or how accurate the predictions were.
