Satellite Functionality Breakdown
Satellites serve diverse functions, including:
- Communications: Facilitating global telephony, internet services, and broadcasting.
- Earth Observation: Monitoring environmental changes, weather patterns, and natural disasters.
- Navigation: Providing positioning services through systems like GPS, GLONASS, and Galileo.
- Scientific Research: Conducting space and Earth sciences experiments. - en.wikipedia.org
- Defense and Intelligence: Supporting military operations and surveillance.
Orbital Distribution
Satellites are positioned in various orbital regimes:
- Low Earth Orbit (LEO): Ranging from 160 to 2,000 km above Earth, commonly used for Earth observation and communication satellites like Starlink.
- Medium Earth Orbit (MEO): Between 2,000 and 35,786 km, typically used for navigation satellites.
- Geostationary Orbit (GEO): At approximately 35,786 km, satellites here remain fixed relative to Earth's rotation, ideal for weather and communication satellites.
Orbital Congestion and Debris
The rapid increase in satellite launches has led to concerns about orbital congestion and space debris. Inactive satellites and fragments pose collision risks, prompting discussions on sustainable space operations and debris mitigation strategies - axios.com.
