Starlink vs Viasat: Real-World Speeds and Value Compared

SkyBeam Editorial TeamSeptember 1, 2026 10 min read

Starlink and Viasat both deliver satellite internet, but they're built on different architectures. Starlink's low Earth orbit constellation offers low latency and high speeds; Viasat's geostationary satellites offer broad coverage with higher latency. Here's how they compare for real-world use.

Key takeaways

Starlink (LEO) has 25–50 ms latency; Viasat (GEO) has 600+ ms.
Starlink is unlimited with deprioritization; Viasat plans often have data thresholds.
Viasat works with a fixed dish; Starlink needs a clear, wide sky view.
Starlink generally wins on speed and latency; Viasat wins on install flexibility.

Architecture and latency

The core difference is orbit. Starlink's LEO satellites at ~550 km give 25–50 ms latency — usable for gaming and video calls. Viasat's geostationary satellites at ~35,000 km give 600+ ms latency, making real-time applications impractical despite adequate download speeds.

Feature	Starlink	Viasat
Orbit	Low Earth orbit	Geostationary
Latency	25–50 ms	600+ ms
Download speed	50–250 Mbps	12–100 Mbps (varies)
Data	Unlimited (deprioritized)	Plans with data thresholds
Dish type	Motorized, tracks satellites	Fixed, points at one satellite

Speed comparison

Starlink generally delivers higher and more consistent speeds, especially on downloads. Viasat's speeds vary more by plan and location, and its higher latency makes even good download speeds feel sluggish for interactive use.

Data policies

Starlink is unlimited with deprioritization during congestion. Viasat plans typically include a data allowance, after which speeds are deprioritized or throttled. For heavy streaming or downloading, Starlink's unlimited model is more predictable.

Coverage and installation

Viasat's geostationary satellites provide broad coverage and work with a fixed dish pointing at one satellite — useful where a wide sky view isn't available. Starlink needs a clear, wide view to track moving satellites, so heavily obstructed sites may suit Viasat better.

Pros

Much lower latency for real-time use
Higher, more consistent download speeds
Unlimited data with no hard caps
Continually expanding and improving constellation

Cons

Needs a clear, wide sky view
Performance depends on obstructions and congestion
Equipment and pricing vary by region
Less suitable for heavily obstructed sites

When Viasat makes sense

Your sky view is too obstructed for Starlink.
You need a fixed-dish install without a wide sky view.
Starlink isn't reliable in your specific location yet.
You're a light data user where Viasat's plan structure fits.

Frequently asked questions

Is Starlink better than Viasat?

For most users with a clear sky view, yes — Starlink has far lower latency (25–50 ms vs 600+ ms), higher speeds, and unlimited data. Viasat may be preferable where Starlink's wide sky-view requirement can't be met or Starlink isn't reliable yet.

Does Viasat have data caps?

Viasat plans typically include a data threshold, after which speeds are deprioritized or throttled during congestion. Starlink is unlimited with deprioritization, which is generally more predictable for heavy users.

Why is Viasat latency so high?

Viasat uses geostationary satellites at ~35,000 km, so signals travel a long distance, producing 600+ ms latency. Starlink's low Earth orbit satellites at ~550 km give 25–50 ms latency — a fundamental architecture difference.
