QZSS: Mission Support
Jump to: Mission Support Status, Current Tracking Statistics, Mission Support Request
On February 28, 2017 the satellite transferred from JAXA to the Cabinet Office, Government of Japan; a summary of the updated information is available and included below.
ILRS Mission Support Status:
QZS-1 precise orbit ephemeris will be transmitted through the QZS-1 Navigation Message in the same way as is currently done in GPS. The mission performs QZS-1 precise orbit determination using L-band Navigation data received at monitor stations. The target accuracy of SIS-URE (radial direction) is several tens centimeters. SLR data from QZS-1 are necessary to estimate navigation data biases and evaluate orbit determination accuracy.
