GEO, MEO and LEO Satellites
GEO, MEO & LEO Satellite Orbits
What Are the Differences and Which One Is Best?
Satellite networks operate in different orbits around Earth — Geostationary (GEO), Medium Earth Orbit (MEO), and Low Earth Orbit (LEO). Each offers specific benefits depending on the mission, location, and performance requirements. This article provides a clear breakdown of the differences between them.
Comparison of GEO, MEO & LEO
| Orbit Type | Altitude Range | Orbital Period | Average Latency | Use Cases |
|---|---|---|---|---|
| GEO | ~35,786 km | 24 hours | ~600 ms | Broadcast TV, traditional VSAT, weather data |
| MEO | ~2,000–20,000 km | 2–12 hours | ~120–150 ms | Navigation (GNSS), enterprise broadband (O3b) |
| LEO | ~500–2,000 km | 90–120 minutes | ~40–70 ms | OneWeb, Starlink, IoT, mobility, remote work |
GEO (Geostationary Earth Orbit)
GEO satellites appear fixed in the sky and provide constant coverage to a specific region. They’re ideal for stable services like TV broadcasting or fixed VSAT connections. However, latency is relatively high and performance suffers in polar regions.
MEO (Medium Earth Orbit)
MEO satellites orbit faster than GEO and offer lower latency. They’re typically used in high-throughput applications like SES’s O3b and GNSS systems. They offer high capacity but need tracking terminals or larger constellations for continuity.
LEO (Low Earth Orbit)
LEO satellites fly much closer to Earth and offer the lowest latency, ideal for real-time applications like voice, video, and remote monitoring. Dense constellations such as OneWeb and Starlink deliver global coverage, including the poles.
When to Use GEO, MEO, or LEO?
- GEO: Reliable for high-capacity, fixed-location services (e.g. Africa broadcast hubs)
- MEO: Best for latency-sensitive enterprise networks with high performance SLAs
- LEO: Ideal for mobile, maritime, offshore, and low-latency use cases
LCS Capabilities Across All Orbits
At Link Communications Systems (LCS), we support all three orbit types:
- GEO: Ku-band and C-band using iDirect, Newtec, and Skyedge
- MEO: SES O3b and mPOWER for low-latency, high-capacity links
- LEO: OneWeb for SLA-backed enterprise use, Starlink for best-effort deployments
We help clients in energy, education, telemedicine, remote work, and maritime sectors choose the optimal solution for their needs.
Summary:
GEO, MEO, and LEO each serve a unique role in satellite connectivity. Understanding the differences allows organizations to choose the right orbit type for performance, reliability, and cost. LCS provides full-spectrum satellite connectivity with trusted service and global reach.
