DATA, COVERAGE AND FREQUENCY

GNSS quality cells from aerial observations are presented on a daily basis. A global map does not mean that every region is observed.

Aircraft readings are dependent on provider access, area and receipt. The date of each observation and its freshness remain visible.

Orbits are based on orbital elements; station measurements on available public acquisitions. Geometric simulation, observation and validation remain distinct.

Replay depends on the archives actually kept. The periods available vary depending on the sources; weather, solar activity and context events do not demonstrate causality.
