OFJ Field Journal from Dave Atkinson - 10/5/95

Thursday, October 5 - Well, after a day of sending electronic mail to JPL and getting responses back every ten minutes (almost) I am now in possession of the second data set needed for the preliminary Doppler Wind Analysis. Interestingly enough, the orbiter trajectory file I am using is not based on the current orbiter trajectory, but describes the ideal trajectory. Every time they do a trajectory correction maneuver (TCM), the Navigation team at JPL tries to put the orbiter back on this ideal trajectory. And, since I don't want to get a new data file every time they do a TCM, I am using the trajectory they expect to be on when the orbiter gets to Jupiter. The final TCMs, called TCM28 and TCM28a, will be in late November.
