Access to reliable internet at sea has become indispensable, whether for safety, operations, or simply staying connected. For years, VSAT (Very Small Aperture Terminal) technology has been the benchmark for maritime connectivity. The arrival of Starlink, with its low-Earth orbit (LEO) satellites, is now completely changing the game.
So, which solution is really right for you? Here's the complete comparison.
Understanding the technologies: LEO vs. GEO
The main difference between Starlink and VSAT lies in the orbit of their satellites.
-
VSAT (geostationary orbit – GEO): satellites 36,000 km from Earth, offering broad coverage but high latency.
-
Starlink (low Earth orbit – LEO): satellites approximately 550 km away, offering very low latency and high speeds.
The comparison: Starlink vs. VSAT
Comparison table
| Features | Starlink Maritime | Traditional VSAT |
|---|---|---|
| Download speed | Up to 220 Mbps | 1 to 25 Mbps |
| Latency | 20–40 ms | 600+ ms |
| Coverage | Global (expanding) | Global with shadow zones |
| Hardware | Compact and lightweight antenna | Bulky antenna |
| Installation | Simple, plug-and-play | Requires a technician |
| Hardware cost | From €2,800 | €10,000+ |
| Subscription cost | €239/month | More expensive |
| Reliability | Very good | Sensitive to rain |
Advantages of Starlink for modern navigation
1. Unmatched speed and responsiveness
Starlink enables uses impossible with traditional VSAT: HD video calls, 4K streaming, online gaming, demanding professional tools…
2. Simple and accessible installation
Installation in minutes, flexible plans, ability to pause service.
3. Compact and affordable hardware
Smaller, lighter, and much more affordable antenna than VSAT.
When does VSAT remain relevant?
VSAT remains useful in specific situations:
-
Guaranteed bandwidth (CIR)
-
Custom solutions for commercial fleets
-
Advanced tools: cybersecurity, SLAs, network management
Conclusion: Starlink, the new standard for maritime internet
For the majority of seafarers—both recreational and professional—Starlink represents a major technological leap: faster, more flexible, more accessible.
VSAT remains relevant in a few specific cases, but the future of connectivity at sea is clearly in low Earth orbit.
