Description
The daily solution files are an analysis product that provides estimates of Earth orientation and site positions for each 24-hour session, the covariance matrix of the estimates, and decomposed normal equations. The solution files are in SINEX format. The SINEX product files are available on the same frequency as the EOP-S products: 24 hours after each new session data base is available.
Data Access
The VLBI Daily Independent solution files are online: https://cddis.nasa.gov/archive/vlbi/ivsproducts/daily_sinex/
