We have added the following satellites to our SLR QC analysis.
JASON-3 (ILRS, AVISO) (abbreviated as JAS3).
GALILEO-201, 202, 203, 204, 205, 206, 208 and 209 (ILRS) (F201 to F209).
GLONASS-125, 128, 133 and 134 (ILRS) (GL25, GL28, GL33, GL34).
We also changed the bias estimation procedure. A pass of high-altitude satellites (GNSS and ETALON) should have >= 4 good NPs, 2 hour coverage, and both ascending and descending parts.
