The plots below show only the last year of the data quality information. The full history of the data quality information can be viewed here
(be patient: it needs time to load).
The monthly skyplots are available here.
The comparison with other stations is available here.
The plots below present the long-term tracking performance of TOIL00EST (Toila, EST).
The numbers are obtained using the G-Nut/Anubis software (versions 2.2.1 (before 2019-03-05), 2.2.4 (from 2019-03-05 to 2019-09-01), 2.3.0 beta (from 2019-09-01 to 2020-09-15) and 2.3 (after 2020-09-15)), developed by the Geodetic observatory Pecný, Czech Republic.
Input files are the daily RINEX 2 and RINEX 3 (if available) observation files.
Only healthy satellites are taken into account (even if tracking unhealthy satellites is still recommended).
For RINEX 2, only and GPS and GLONASS data are considered.
The percentage corresponds, for each constellation tracked by the station, to the ratio of the number of
observations in the daily RINEX file with respect to the number of expected observations:
1 freq. : all observations are counted.
2+ freq.: only observations on at least two frequencies are counted. These are the observations useful for geodetic positioning.
The black horizontal line indicates the elevation cut off angle as set in the station log file. The
purple line is the lowest elevation cut off observed in the RINEX data. Red, green and blue vertical lines indicate respectively a change of antenna, receiver or receiver configuration (including firmware).
These plots display, for each constellation tracked by the station, the number of missing epochs. The TOT (total) value takes all constellations into account.
Red, green and blue vertical lines indicate respectively a change of antenna, receiver or receiver configuration (including firmware).
These plots display the number of observed healthy satellites for each constellation tracked by the station.
Red, green and blue vertical lines indicate respectively a change of antenna, receiver or receiver configuration (including firmware).
These plots display, for each constellation tracked by the station, the maximum of the number of observations counted for each frequency. The TOT (total) value is the sum of all maxima.
Red, green and blue vertical lines indicate respectively a change of antenna, receiver or receiver configuration (including firmware).
These plots display the number of identified phase cycle slips for each constellation tracked by the station.
Red, green and blue vertical lines indicate respectively a change of antenna, receiver or receiver configuration (including firmware).
These plots display the code multipath for each constellation on each frenquency tracked by the station.
Code multipath statistics are calculated for all pseudo-range codes of all GNSS satellites providing dual-frequency carrier-phase observations.
The statistics are represented as the average RMS of code multipath calculated after removing a systematic error from the multipath linear combination.
Red, green and blue vertical lines indicate respectively a change of antenna, receiver or receiver configuration (including firmware).
