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.
