This ORT was over DSS 15, and it simulated three orbits. There was one problem with the transmitter during one of the two-way periods, and it switched off early. (DR #G02522 was written by the station.) This would have resulted in a loss of about 15 minutes of Gravity Field data during mapping operations. All of the one-way data was acquired without any problems. Except for the transmitter glitch, the ORT went very well. This was the first ORT conducted with the latest DSP-R software upgrade. We were unable to use the new Radio-Science-generated predicts capability because of an FTP configuration problem identified during last week's DSP-R testing. This problem is in the process of being resolved. For this ORT, we used the usual DSN-generated predicts. We used the reliable data delivery route for all data except the last egress. Currently, it will require human intervention in order for the data to reach the TDS. It is my understanding that this will become automatic -- as it is for telemetry data. Therefore, data from the last egress is already on the TDS with no missing records and ready for immediate queries. I will inform Stanford as soon as the remainder of the data is available. In addition to the egress data, we recorded the MOT warm-up period before every egress. A "script" will be placed on mgrs with the specific data record times. I would like to thank the station personnel, the NOPEs, and the ACE for their support. If you have any questions or comments about the ORT, please let me know. -Trish
