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. As informed from Mr. Shinichi Nakamura, contact person of QZS-1 tracking changes to us below, Hiroyuki Noda (JAXA, QZSS Project) noda.hiroyuki@jaxa.jp Motohisa Kishimoto (JAXA, QZSS Project) kishimoto.motohisa@jaxa.jp We hope continuous SLR operation to QZS-1 after campaign for accuracy improvemnet of the QZS-1 orbit estimation. Now, we are concerning the condition of core time etc. Please wait for a while.
