id field name definition 0 Orbit xml record id field name definition 0 Absolute_Orbit ascii int32 absolute orbit counter. This counter is incremented by one unit from a record to the next. It must be differenciated with the real absolute orbit number on which the state vector (OSV record) really belongs i.e : if the Z value of the OSV is >= 0 then "real" absolute orbit number equal the absolute orboit counter if the Z value of the OSV is < 0 then "real" absolute orbit number equal the absolute orbit counter minus 1 1 Relative_Orbit ascii int32 Relative orbit number 2 Cycle_Number ascii int32 Cycle number; incremented after each new repeat cycle 3 Phase_Number ascii int32 Phase number; incremented on Mission Management decision 1 Cycle xml record id field name definition 0 Repeat_Cycle ascii int16 attribute: unit ascii string size: 3 fixed value: "day" 1 Cycle_Length ascii int16 attribute: unit ascii string size: 5 fixed value: "orbit" 2 ANX_Longitude ascii double Longitude of ascending node crossing (ANX) unit: "degrees_east" attribute: unit ascii string size: 3 fixed value: "deg" 3 MLST xml string 4 MLST_Drift ascii double Drift of mean local solar time over 1 orbit unit: "s/day" attribute: unit ascii string size: 5 fixed value: "s/day" 2 Time_of_ANX xml record id field name definition 0 TAI xml time TAI date and time of ANX, in ASCII CCSDS time format, including time reference and microseconds unit: "s since 2000-01-01" value: if(length(.) == 0, nan, if(str(., 30) == "TAI=9999-99-99T99:99:99.999999", +inf, if(str(., 30) == "TAI=0000-00-00T00:00:00.000000", -inf, time(str(.), "'TAI='yyyy-MM-dd'T'HH:mm:ss.SSSSSS")))) xml string 1 UTC xml time UTC date and time of ANX, in ASCII CCSDS time format, including time reference and microseconds unit: "s since 2000-01-01" value: if(length(.) == 0, nan, if(str(., 30) == "UTC=9999-99-99T99:99:99.999999", +inf, if(str(., 30) == "UTC=0000-00-00T00:00:00.000000", -inf, time(str(.), "'UTC='yyyy-MM-dd'T'HH:mm:ss.SSSSSS")))) xml string 2 UT1 xml time UT1 date and time of ANX, in ASCII CCSDS time format, including time reference and microseconds unit: "s since 2000-01-01" value: if(length(.) == 0, nan, if(str(., 30) == "UT1=9999-99-99T99:99:99.999999", +inf, if(str(., 30) == "UT1=0000-00-00T00:00:00.000000", -inf, time(str(.), "'UT1='yyyy-MM-dd'T'HH:mm:ss.SSSSSS")))) xml string
