SKYOS is a real-time 3D space simulation built around a living sky and real-time orbital experience.
Earth rotates and evolves with real date and time. Day and night, seasons, orbital motion, constellations, solar alignment, and celestial events are designed to create a persistent and immersive space-time environment.
Observe Earth and the sky in real time, explore the Solar System at macro scale, visualize constellations and zodiac layers, and follow orbital activity around Earth. Real-time satellite positions, weather satellite imagery, and space-related visual data are integrated to create a dynamic and evolving simulation.
SKYOS also features cinematic Earth-to-Moon mission flow with transitions from micro to macro scale. Launch from Earth, follow real-time aligned launch windows, and execute orbital transfer phases including TLI, LOI, TEI, and EOI. Orbital paths and transfers are shaped by gravitational influence and can be visualized through dynamic gravity field representation.
The simulation also includes eclipse prediction systems and an early ISS observation/visit layer, allowing players to access basic station views and interior observation points such as the Cupola.
Features:
- Real-time Earth and sky synchronization
- Real-time aligned orbital and celestial systems
- Real-time satellite position visualization
- Weather satellite imagery and captured space data visualization
- Earth-to-Moon mission flow from launch to transfer
- TLI, LOI, TEI, and EOI orbital phases
- Micro to macro scale transitions
- Visualized gravity fields and gravity-driven orbital trajectories
- Dynamic constellations and zodiac layers
- Orbital visualization and satellite tracking
- Eclipse prediction systems
- Early ISS observation and interior viewing
- Cinematic space travel and planetary approach
SKYOS is designed as a prestige real-time space simulator for players who want to observe, explore, and experience a living space environment grounded in real-time motion and orbital perspective.
