There was a total of 22 tracking passes in February of 1999 with 1 of these being an unattended tracking pass. Of the 21 attended tracking passes 18 collected the maximum amount of valid data possible. The unattended tracking pass collected the maximum amount of good data. There were 7 tracking passes that lost data due to problems on HALCA pointing to the GBES late. Four tracking passes failed completely due to problems with HALCA.
Of the 5 recording passes, all 4 collected the maximum amount of good data and no recording data was lost.
A communications problem between the station computer and the TWT module firmware resulted in most of the data from one tracking pass being corrupted.
18 of 21 attended passes had max good data.
Operators helped increase amount of good data in 3 of 3 ``bad'' attended passes.
1 of 1 unattended passes had max good data.
A total of 0.16 tracking passes lost data due to problems with SRT and orbit predictions.
A total of 0.63 tracking passes lost data due to software problems.
A total of 0.21 tracking passes lost data due to hardware problems.
A total of 4.00 tracking passes lost data due to HALCA DHU problems.
5 of 5 recording passes were completely successful (all recording data collected successfully).
