         MADOCALIB: MADOCA-PPP Test Library

--------------------------------------------------------------------------------

# OVERVIEW

MADOCA-PPP test library is a reference implementation of MADOCA-PPP, and it contains a post-processing PPP utility. Please note it doesn't assure anything in terms of its effectiveness or reliability.

MADOCA-PPP is Multi-GNSS Advanced Orbit and Clock Augmentation - Precise Point Positioning service of QZSS.

The library is derived from RTKLIB (version 2.4.3 b34, Ref. Note1) and functions of PPP-AR and message conversion copyrighted by the third party.


# USAGE
Go to the folder of "sample_data". Double-click and excute the batch file of 
"exec_ppp.bat" on your Windows PC.
Please refere to the MADOCALIB manual for usage of MADOCALIB in detail.

                      discontinuity indicator.
                      Apply phase bias correction only when performing 
                      ambiguity resolution.
                      Other performance improvements.
* 2024/11/22 1.4  - The 4th public version.
                      Support for multiple L6D file input for rnx2rtkp.

                      Fix bug for incorrect maxframe calculation for L6D decoding.
                      Apply phase bias correction even when ambiguity resolution 
                      is not performed.
* 2025/05/26 1.5  - The 5th public version.
                      PPP processing is performed normally even when an undefined
