Plot legend:
- Epoch summary (EPO):
- Usable: ratio of epochs with four satellites with dual-frequency observations at least (expected 100%)
- Exists: ratio of existing epochs (expected 100%)
- xEpCod: ratio of missing epochs due to single-freq. pseudo-range observations (expected 100%)
- xEpPha: ratio of missing epochs due to single-freq. carrier phase observations (expected 100%)
- Observation and satellite statistics (OBS):
- SAT: observed satellites (expected GPS:30, GLO:24)
- OBS: existing observations (expected 4 at least)
- HDR: reported observations (expected 4 at least
- Individual observation ratios (RAT):
- ZERO: Have/expected ratio for zero-elevation mask (expected 100%)
- USER: Have/expected ratio for 15dg-elevation mask (expected 100%)
- ELEV: Availability of elevations (expected 100%)
- Data interruptions, slips, gaps and pieces (SLP):
- Jumps: Detected clock jumps (0 expected)
- Gaps: Detected data gaps (0 expected)
- Piece: Detected data small pieces (0 expected)
- Slips: Detected phase cycle slips (0 expected)
- csAll: All phase interuptions including cycle slips (0 expected)
- csEpo: Phase interruptions due to missing epoch (0 expected)
- csSat: Phase interruptions due to missing satellite (0 expected)
- csSig: Phase interruptions due to missing signal (0 expected)
- Dual-frequency observations (DUA) for indidivual satellites (expected 100%):
- Mean multipath and noise (MPT) characteristics for individual code observations (lower better):
- Mean signal-to-noise ratio (SNR) characteristics for individual phase observations (lower better):
- Daily NEU coordinate repeatability (REP) from standard positioning (15 min sampling)
using a stand-alone GNSS solution and supported with global navigation messages
(yellow: problematic epochs)
- Daily coordinate residuals (CRD) time-series from a stand-alone GNSS standard positioning
(yellow: problematic epochs, black: too large outliers)
