Features
Quick Fact
|
Feature |
Low Earth Orbit (LEO) |
Sun Synchronous Orbit (SSO) |
|
Altitude |
160–2,000 km; LEO is the broad orbital regime. |
500 – 800 km; specialised orbit within LEO, critical for Earth observation satellites |
|
Inclination |
Variable (depends on mission) |
Near polar, 97°–99° (98° typical) |
|
Coverage |
Small footprint; requires constellations for global coverage |
Passes the same area at the same local solar time daily |
|
Applications |
Communication constellations (e.g., Starlink), ISS and general Earth observation |
Remote sensing, cartography, weather and environmental monitoring |
|
Energy Requirement |
Lower; easier to reach |
Higher, precise altitude + inclination needed |
