Based on mass of the satellite:
Type | Mass |
Large | > 1000 kg |
Medium | 500–1000 kg |
Mini | 100–500 kg |
Micro | 10–100 kg |
Nano | 1–10 kg |
Pico | < 1 kg |
By Orbit Altitude:
Orbit Type | Altitude Range |
Low Earth Orbit (LEO) | 200–2000 km |
Medium Earth Orbit (MEO) | 2000–35786 km |
Geostationary Orbit (GEO) | 35786 km (fixed over equator) |
By Application different types of satellites:
