Observed/predicted number of observations(over one sliding year) | Delayed Time latency(over one sliding week) |
This percentage corresponds to the ratio number of complete observations with respect to the number of predicted observations for a fixed elevation cut off angle of 3°. It is computed from Rinex3 Daily/30s Anubis quality files for GPS, GLO, GAL, BDS and QZS (when available) constellations since 2020-11-17, and from Rinex2 Daily/30s files for GPS, GLO, GAL, SBAS constellations before this date. | Latencies based on the provision of the Rinex 3.02, 3.03 and 3.04 data every fifteen minutes |
No data available. Day of the year (Day 1 to 365) | No data available. Day of the year (Day J-6 to J-1) |
