Satellite Flag Pro

Predictions for satellite passes, Iridium flares, and local sunrise and sunset

Satellite Flag provides precise offline predictions for Iridium flares, ISS passes, brightest satellite passes, and local sunrise and sunset times.

Predictions are calculated for your current location using orbital information supplied by NORAD. Ideal for offline working in the field.

Current features include :

- brightest satellites pass predictions

- Iridium flare predictions

- ISS pass predictions

- real-time orbital information

- real-time ground-tracking

- local sunrise and sunset information

- responsive sky map using device orientation*

Please note that many of the first-generation Iridium satellites are now being de-orbited. Since their attitudes are no longer tightly managed some flare predictions may be less reliable.

* available for devices with a compatible magnetometer sensor
