SatViewer3D의 궤도 데이터는 얼마나 정확한가요?

Space-Track과 CelesTrak에서 매일 갱신되는 공인 TLE 데이터를 SGP4 모델로 실시간 계산하므로 수 킬로미터 이내의 높은 정확도를 제공합니다.

인공위성을 육안으로도 볼 수 있나요?

네! 해질녘이나 일출 전 어스름할 때, ISS나 스타링크 기차는 태양빛을 반사하여 밤하늘을 조용히 가로지르는 밝은 별처럼 선명하게 관측됩니다.

학교 수업이나 연구에 사용할 수 있나요?

언제든 환영합니다. SatViewer3D는 회원가입 없이 무료로 개방된 교육용 오픈 플랫폼입니다.

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.
