About this map & FAQ

Satellite coverage map & live direct-to-cell tracker

GroundOrbit’s live coverage map shows real-time satellite ground tracks and positions for AST SpaceMobile, Starlink, Lynk and OneWeb over a global mobile-network speed heatmap. Tap anywhere for a 0–100 Connectivity Reliability Score that fuses mobile (LTE/5G) and satellite direct-to-cell availability — so you can see where, and when, you’ll have a connection, ground to orbit.

Frequently asked questions

Is there a live satellite coverage map?

Yes. This map shows real-time satellite ground tracks and positions for direct-to-cell constellations (AST SpaceMobile, Starlink, Lynk, OneWeb), computed live with SGP4 from public orbital data — no stale snapshots.

How do I check when a Starlink or AST SpaceMobile satellite is overhead?

Search or tap your location on the map, or open the Satellite API. It computes upcoming direct-to-cell passes — start time, peak elevation and duration — so you can see exactly when a satellite will be over you.

Does the map show mobile network coverage too?

Yes. A global mobile-network speed heatmap (from Ookla Open Data) sits under the satellites, so you can compare terrestrial LTE/5G quality and satellite direct-to-cell availability in one view.

What is the Connectivity Reliability Score?

Tap anywhere and GroundOrbit returns a single 0–100 score that fuses mobile (LTE/5G) and satellite direct-to-cell availability at that location, with a grade, confidence and an explainable breakdown.

Can I check connectivity along a route?

Yes — Route mode lets you drop start, via and destination pins; it scores connectivity along the great-circle path and highlights the weakest stretch and worst coverage gap.
