| 3 | Absolute_Orbit |
| ascii uint32 |
|---|
|
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 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
