Qual é a precisão dos dados mostrados no SatViewer3D?

Os cálculos utilizam o modelo analítico SGP4 e elementos TLE oficiais diários, assegurando precisão na casa de poucos quilômetros.

É possível ver satélites a olho nu?

Sim! No crepúsculo da manhã ou da tarde, satélites como a ISS e o trem Starlink refletem a luz do Sol e cruzam o céu como estrelas velozes.

Posso usar o simulador em aulas e palestras?

Com certeza. O SatViewer3D é livre, gratuito e dispensa qualquer cadastro.

How does SatViewer3D compute real-time satellite positions?

SatViewer3D fetches official TLE (Two-Line Element) orbital sets curated by NORAD and CelesTrak. It computes precise satellite positions and velocities in real-time using the standard SGP4 (Simplified General Perturbations-4) mathematical perturbation model.

Can I track the International Space Station (ISS) in real time?

Yes! You can instantly locate and focus on the ISS via the top presets or sidebar. SatViewer3D displays its ground track, orbital altitude, velocity, and offers an immersive astronaut POV from the ESA Cupola observation deck.

Does SatViewer3D work on mobile and tablet devices?

Yes. The simulator is fully responsive with intuitive multi-touch gestures (two-finger pinch zoom, drag rotation) across iOS Safari, Android Chrome, and modern desktop browsers without requiring app installations.

What is space debris and why is it dangerous?

Space debris consists of defunct satellites, spent rocket stages, and fragments moving at orbital speeds of 7 to 8 km/s. Even millimeter-sized debris can inflict catastrophic damage to operational spacecraft, posing a threat of cascading collisions known as Kessler Syndrome.
