Multi-GNSS Advanced Orbit and Clock Augmentation - Precise Point Positioning (MADOCA-PPP) Service
Outline
This is the download site for QZSS archives about MADOCA-PPP.
Note:
Because of maintenance period of ground systems, etc., some data may be missing. Ionospheric correction data may not be delivered depending on the availability of source data from the local monitoring stations. PPP with reduced initial convergence time by ionospheric correction in the relevant region is not available in that case, but normal PPP with orbit, clock, and bias correction is available as usual.
Information and Histories of Internet Distribution
Note:
Operational information of the QZSS satellites is provided by NAQUs.
Data Definition
The site provides broadcasted L6E and L6D messages generated by MADOCA-PPP as hourly binary files for each satellite.
L6E messages are assigned to PRNs 204-207, 209-211 and L6D messages are assigned to PRNs 200 and 201.
The L6E messages contain clock/ephemeris corrections and the L6D messages contain ionospheric corrections.
In the current operation, clock/orbit corrections are distributed for the same satellite in all PRNs, while ionospheric corrections are distributed for different service areas in each PRN.
For data formats, refer to section 4. of IS-QZSS-MDC for L6E messages and refer to section 6. of IS-QZSS-MDC for L6D messages.
