Subject: [SLR-Mail] No. 1939: Change Contact Person on QZS-1 Tracking From: Shinichi Nakamura, JAXA > ******************************************************************************** SLR Electronic Mail 2010-12-17 11:22:00 UTC Message No. 1939 ******************************************************************************** Author: Shinichi Nakamura, JAXA Subject: Change Contact Person on QZS-1 Tracking Subject: Change Contact Person on QZS-1 Tracking Subject: Change Contact Person on QZS-1 Tracking Dear ILRS Colleagues, We really appreciate ILRS support for QZS-1 tracking campaign. We could obtain good SLR data to evaluate the QZS-1 orbit estimated by navigation signal. I would like to report a change of contact person of QZS-1 tracking. (from) Shinichi Nakamura (JAXA, Flight Dynamics Team) nakamura.shinichi@jaxa.jp Ryo Nakamura (JAXA, Flight Dynamics Team) nakamura.ryoh@jaxa.jp Takahiro Inoue (JAXA, Flight Dynamics Team) inoue.takahiro@jaxa.jp (To) Hiroyuki Noda (JAXA, QZSS Project) noda.hiroyuki@jaxa.jp Motohisa Kishimoto (JAXA, QZSS Project) kishimoto.motohisa@jaxa.jp Please note that this change is applied only ”QZS-1 tracking”. By the way, QZS-1 tracking campaign will terminate soon. After campaign period, QZS-1 tracking will move to nominal SLR tracking operation. New contact person will inform our request during QZS-1 nominal SLR tracking operation, such as core time, etc. Best Regards, Shinichi Nakamura PS Of course, we will report the results of QZS-1 tracking campaign on next ILRS symposium.
