     CHANGED (28.09.2017): Transformation of orbit and clock corrections into ETRF2000,
                           NDA83 or DREF91 is done temporarily via ITRF2008
+    FIXED   (22.03.2018): consideration of DF range 0-63 for SSR Satellite IDs as
+                          defined in DF463, DF466. First BDS or SBAS satellite is 0
     FIXED   (05.02.2018): Bug in latency checker
     FIXED   (13.12.2017): Galileo geocentric gravitational constant is corrected
