[IGSMAIL-8670] Correction: GFZ MGEX Products Update (Plain Text)

[Zhiguo Deng]

Dear colleagues,

In accordance with the MGEX requirements, the GFZ MGEX official products 
have been generated using updated BeiDou satellite antenna phase center 
corrections since 08 February.

In the new release, BDS-3 satellites are processed using B1c/B2a 
observations (L1/L5), while BDS-2 satellites continue to use B1I/B3I 
observations (L2/L6). The updated products treat BDS-2 and BDS-3 as two 
fully independent systems.

The GFZ MGEX products (GFZ0MGX) remain available via CDDIS. In addition, the 
GBM0MGX products can be accessed from the GFZ FTP directory:

WWWW_B1C

Users are advised to ensure consistency in observation types, satellite 
antenna corrections, and processing strategies when using these products.

The previous combined BDS-2/3 solution (based on unified B1I/B3I 
observations) will continue to be provided and can be downloaded from the 
GFZ FTP directory:

WWWW_IGS20

Please feel free to contact us if you have any questions.

Best regards,
Zhiguo Deng
