 - ADDED: **SSR QC** of decoded Broadcast Correction streams (options 'QC Directory', 'QC Streams', 'QC Reference', 'QC Interval'; example configuration '31_SsrQC.bnc'). One daily report file per stream with epochs, declared and actual update intervals, gaps, latency, completeness w.r.t. healthy broadcast ephemerides, IOD matching, code and phase bias signals, yaw angle availability, missing code biases of the reference signals, clock jumps and largest orbit corrections
 - ADDED: Stream comparison in the SSR QC: orbits (radial, along, cross), clocks referred to the reference signals and signal-in-space differences (SIS = radial - clock) of each stream compared with the consensus of the other ACs (one vote per AC, own AC left out, combination products not voting) or with a selected stream (e.g. 'INTERNAL'), as RMS and standard deviation per satellite and system
+- ADDED: Code bias check in the SSR QC: the DCBs of each stream are compared with each other AC and optionally with a Bias SINEX file (option 'QC Bias File'); a stream with the opposite sign for most DCBs (SINEX instead of SSR sign convention) is reported
 - ADDED: SIS (radial - clock, satellite-specific clock offset included) per epoch and SISRMS/SISSig per satellite and system in the SP3 comparison
 - CHANGED: SP3 comparison: the clock offsets are estimated with the epoch offsets eliminated from the normal equations (identical result); a daily file with 30-second sampling is now compared in seconds instead of hours

 - ADDED: Combination: hourly report of AC satellites persistently rejected as outliers, and of satellites skipped because fewer than 2 ACs provide corrections
 - ADDED: Combination of APC (SSRA) and CoM (SSRC) streams together: with an ANTEX file the combination is done in the CoM frame, the orbits of the APC streams are converted to CoM; ACs not combined because of a different reference point are reported
+- ADDED: Option 'Reference Signals' (key ssrRefSignals): reference signals of the satellite clocks per GNSS for the combination (AC clock referral, code biases from the Bias SINEX file) and the SSR QC, default IGS Real-Time convention G:1W&2W R:1P&2P E:1C&5Q C:2I&6I J:1C&2L S:1C&5Q, e.g. for a switch of BDS to C1P/C5P or of QZSS to L1/L5
 - ADDED: Detection and conversion of outdated or erroneous IGS-SSR epoch time encodings (GLONASS as UTC seconds of day or of week, BDS as BDT) with an hourly warning, and a plausibility check of the orbit/clock epochs of all systems of a stream
 - ADDED: ANTEX file name, number of entries and latest satellite entry are logged; satellites without a valid ANTEX entry are reported (and not combined)
