Open mapOUR APPROACH
Satellite navigation supports transport, positioning and clock synchronization. Understanding GNSS variations requires comparing observations with their sources, time and coverage.
PROVENANCE
Dates, origin and conditions of use accompany the data. An analysis remains verifiable.
TRANSPARENCY
Coverage varies by region and time period. The absence of data is never presented as an absence of risk.
INTERPRETATION
Degraded navigation quality does not by itself confirm interference. SatellAItes supports exploration and analysis; it is not a certified navigation system.

Satellite positions are calculated from orbital elements. Station measurements come from available public data acquisitions. Modelled geometry and measured observations must be interpreted separately.
Historical playback uses only the archives retained by the service. Available periods vary by source. Weather, solar activity and other contextual events do not establish the cause of a GNSS disturbance.
UTC, TAI and time zones on the map and globe
A discreet clock shows the current UTC date and time in the top-right corner of the map and globe. Its NTP reference is obtained server-side from METAS; network delay is compensated and an estimated precision margin is displayed. Visible milliseconds do not guarantee metrological accuracy to one millisecond.
TAI appears below UTC with its current offset: TAI − UTC = +37 s. It is derived from synchronised UTC and the official offset. UTC and TAI use the same SI second; the 0.9 s limit concerns UT1−UTC, not TAI−UTC.
Open the time-reference group in the layer menu and enable Time Zone. Fine outlines show civil time zones, including oceans, with current local times and GMT±HH:mm offsets. Daylight saving rules and half-hour or quarter-hour offsets are included. Boundaries are simplified for display and remain approximate.
Hover over a zone for a temporary tooltip; click or tap to keep a panel open with its date, local time and GMT offset. Close it with ×, Escape or an outside click. UTC/TAI clock information is also available on hover, click and keyboard: Tab, then Enter or Space.
These clocks show the current time independently of the selected analysis period. When comparing observations, retain the analysis date and UTC interval. Without a valid UTC reference, no substitute local or TAI time is invented; time-zone outlines may remain visible.
