QZS-1 (Quasi-Zenith Satellite 1) has been launched on 11/Sep. After launching, many initial check have been done successfully. The satellite orbit takes it over the laser ranging stations of the Western Pacific Laser Tracking Network (WPLTN), in Japan, China and Australia. The QZS-1 project has requested an ILRS-WPLTN tracking campaign for the satellite for orbit determination/estimation of clock bias studies. Your tracking support is vital to making this activity a success. We ask that our colleagues in the WPLTN make every effort to track QZS-1. (1) About QZS-1 Altitude: 32,618-38,950 km Inclination: about 41 degrees Eccentricity: 0.099 (2) Purpose of ILRS campaign Precise orbit determination Estimation of clock bias (3) Satellite ID SIC Number 1581 COSPAR ID 2010-045A NORAD Number 37158 (3) Normal bin size : 5 min (4) Period From 30/Nov. (UT) to 7/Dec. (UT) [1 week] (5) Core Time 9:00 -- 9:20 (UT) 12:00 -- 12:20 (UT) 15:00 -- 15:20 (UT) 18:00 -- 18:20 (UT) 21:00 -- 21:20 (UT) (6) CPF will be distributed by CDDIS server. (7) Point of Contact Person SLR operation, Shinichi Nakamura, nakamura.shinichi@jaxa.jp QZS-1 satellite, Hiroyuki Noda, noda.hiroyuki@jaxa.jp Continued tracking support by ILRS is vital to the success of the QZS-1 missions. Thank you for your cooperation. From: Nakamura Shinichi ********************************************************************************
