G-Nut/Anubis - summary output

First line of the Anubis report shows applied version of the software, compilation time and SVN revision number. # G-Nut/Anubis [2.0.0] compiled: Oct 12 2016 11:55:54 ($Rev: 1645 $)

Summary section of the Anubis report suggest a low or high verbosity. If sec_sum="1" is used, an overall single-line summary is provided for each GNSS constellation (see listing below). #====== Summary statistics (v.1) #TOTSUM First_Epoch________ Last_Epoch_________ Hours_ Sample MinEle #_Expt #_Have %Ratio o/slps woElev Exp>10 Hav>10 %Rt>10 =TOTSUM 2016-04-09 00:00:00 2016-04-09 23:59:30 20.65 30.00 0.00 91951 62389 67.85 51 336 66191 55086 83.22 #GNSSUM 2016-04-09 00:00:00 Epoch_Statistics_ Excl_Epochs&Satellites_ CycleSlips/Interruptions_And_Other_Discontinuities Code_Multipath_Mean_Statistics$ #GNSSUM 2016-04-09 00:00:00 Epoch_Statistics_ Excl_Epochs&Satellites_ CycleSlips/Interruptions_And_Other_Discontinuities Code_Multipath_Mean_Statistics_Over_All_Signals #GNSSUM 2016-04-09 00:00:00 ExpEp HavEp UseEp xCoEp xPhEp xCoSv xPhSv csAll csEpo csSat csSig nSlp nJmp nGap nPcs mp1 mp2 mp3 mpx mp5 mp6 mp7 mp8 =GPSSUM 2016-04-09 00:00:00 2880 2478 2478 0 0 533 533 639 68 280 200 91 0 3 0 34.4 31.7 - - 34.0 - - - =GALSUM 2016-04-09 00:00:00 2880 2478 989 1489 1489 11 11 159 28 80 23 28 0 3 0 26.0 - - - 31.3 - 34.9 10.7 =GLOSUM 2016-04-09 00:00:00 2880 2478 2478 0 0 940 945 1762 74 487 141 1060 0 3 0 51.3 43.2 - - - - - - =BDSSUM 2016-04-09 00:00:00 2880 2478 1688 789 790 39 41 115 16 25 40 34 0 3 0 39.2 - - - - - 27.2 -

Description of columns in overall summary (extended teqc single-line) is following:

• Hours_ - data length in hours (estimated from total number of epochs and sampling rate)
• Sample - data sampling interval (estimated from elevation histogram)
• MinEle - data minimum elevation angle observed
• #_Expt - number of expected observations above the horizon (carrier phases with maximum observations over GNSS counted)
• #_Have - number of existing observations above the horizon (carrier phases with maximum observations over GNSS counted)
• %Ratio - ratio of existing and expected observations above the horizon (calculated form above values)
• o/slps - number of observations per cycle slip
• woElev - number of observations with available elevation (no satellite position available)
• Expt>10 - number of expected observations above user mask (carrier phases with maximum observations over GNSS counted)
• Have>10 - number of existing observations above user mask (carrier phases with maximum observations over GNSS counted)
• %Rt>10 - ratio of existing and expected observations above user mask (calculated form above values)

Description of columns in GNSS-specific summary is following:

• ExpEp - number of expected epochs (uses pre-defined data interval and sampling or suggests from data if not available)
• HavEp - number of available epochs (really counted epochs)
• UseEp - number of usable epochs (criterion is 4 satellites in the epoch with dual-frequency data in each GNSS constellation)
• xCoEp - number of epochs with less than 4 satellites providing dual-frequency pseudorange observations
• xPhEp - number of epochs with less than 4 satellites providing dual-frequency carrier-phase observations
• xCoSv - number of single-frequency pseudorange data only
• xPhSv - number of single-frequency carrier-phase data only
• csTot - number of total phase cycle-slips or interruptions (in general means request to setup a new initial phase ambiguity
• csEpo - number of interruptions due to missing epoch (counts all previously observed satellite)
• csSat - number of interruptions due to missing satellite at a specific epoch (where it is expected)
• csSig - number of interruptions due to missing signal from the satellite (others are available)
• nSlp - number of identified phase cycle-slips when continuous tracking is available for specific satellite and signal
• nJmp - number of identified receiver clock jumps
• nGap - number of data total gaps (according to the setting int_gap="600" in seconds)
• nPcs - number of small data pieces (according to the setting int_pcs="1800" in seconds)
• mpX - code multipath moving average RMS [cm] for the 1st..8th band, (mean value over all available signals at the 1st..8th band)

High verbosity provides results of statistics of individual observation types of all available GNSS constellations (see listing below). The following columns are available with/without navigation messages:

• nSat - number of observed satellites
• ExpObs - number of expected observations (an estimate)
• obs[%] - existing observations w.r.t. to expected
• nor[%] - existing observations w.r.t. to expected, but normalized with rate of existing satellites vs. total expected in the constellation
• CS_Tot - number of total phase cycle-slips and phase interruptions
• CS_Epo - number of carrier-phase interruptions due to missing epoch (counted for all previously observed satellites and signals)
• CS_Sat - number of carrier-phase interruptions due to temporary unavailable satellites
• CS_Sig - number of carrier-phase interruptions due to temporary unavailable signals
• CSlips - number of identified real phase cycle-slips in a continuous phase tracking

If navigation messages for specific constellations are available (over the whole QC period!), all intervals of individual satellite visibility can be theoretically calculated and expected observations estimated. Histograms of observations available in columns 0[%] and 0-10, 10-20, .., 80-90 elevations are additionally provided. However, these are actually time-consuming procedures and rather tricky if not all relevant navigation messages are available. Thus the features are supported only experimentally with an extra high verbosity via setting sec_sum="9".
