Geostationary vs LEO Satellite Internet

The two main categories of satellite internet — geostationary and low-earth-orbit — take fundamentally different engineering approaches to connecting you to the internet. Those differences produce dramatically different latency, speed, dish hardware, and pricing, all of which matter when you are deciding which service to choose.

Geostationary Satellite Internet (GEO)

Geostationary satellites orbit Earth at exactly 35,786 km above the equator. At that precise altitude, a satellite's orbital velocity matches Earth's rotational speed, so the satellite appears to hover motionless over the same point on the ground around the clock. This property has two significant practical advantages.

First, a single satellite at GEO altitude has an enormous footprint — it can see roughly one-third of Earth's surface simultaneously, which means just three satellites positioned at equal intervals around the equator can provide near-total global coverage (excluding the polar regions). Second, because the satellite does not move relative to the ground, a user's dish simply points at a fixed spot in the sky. A basic parabolic dish with no moving parts or tracking electronics can maintain a stable connection indefinitely.

The downside of geostationary orbit is unavoidable: physics. Signals must travel roughly 35,786 km from your dish to the satellite, then another 35,786 km from the satellite down to the ground station — a one-way trip of over 71,000 km. At the speed of light, that takes about 238 ms for just those two legs. Add the return path and terrestrial routing, and round-trip latency regularly exceeds 500 ms. For web browsing and streaming, this is tolerable. For gaming, video conferencing, or VoIP, it makes the service genuinely frustrating.

HughesNet and Viasat are the two dominant geostationary consumer satellite providers in the United States. HughesNet's Gen 5 service operates from the EchoStar XIX satellite. Viasat-3, launched in 2023, delivers up to 150–500 Mbps in some beams — the fastest speeds available on GEO — though average customer experience is typically far below that headline figure due to how bandwidth is shared across the beam.

Low-Earth-Orbit Satellite Internet (LEO)

Low-earth-orbit satellites fly at altitudes between roughly 160 km and 2,000 km. Starlink, operated by SpaceX, uses an orbit of approximately 550 km for its main operational shell. At this height, the signal distance from dish to satellite is about 550–700 km depending on the satellite's elevation angle — roughly 65 times shorter than the GEO path. That reduction in distance cuts the round-trip propagation delay from hundreds of milliseconds to just a few milliseconds, which is why Starlink achieves 20–60 ms latency rather than 500–700 ms.

The engineering challenge at LEO is coverage continuity. Because LEO satellites move so rapidly relative to Earth's surface — completing a full orbit in about 90 minutes — a single satellite is only visible from any given location for a few minutes before it disappears below the horizon. Providing uninterrupted service therefore requires a large constellation of satellites so that multiple spacecraft are always within view. Starlink operates approximately 6,000 satellites as of 2025, with a licensed constellation of up to 42,000. Amazon's Project Kuiper aims for 3,236 satellites at similar altitudes.

User dishes for LEO service are correspondingly more sophisticated. Starlink's Gen 3 dish is a flat phased-array panel that electronically steers its beam across a wide arc of sky, tracking each satellite as it rises, flies overhead, and sets — performing a handoff to the next satellite in view approximately every 15 seconds. There are no motors or moving parts; steering is done by controlling the phase of signals across an array of small antenna elements.

Medium-Earth-Orbit (MEO) Briefly

A third category, medium-earth-orbit, occupies the space between roughly 2,000 km and 35,786 km. O3b mPower, operated by SES, uses a constellation of satellites at about 8,062 km altitude. Round-trip latency on MEO sits around 100–150 ms — better than GEO but not as low as LEO. MEO satellite internet is aimed primarily at enterprise customers, shipping companies, and governments rather than residential consumers, and it does not compete directly with Starlink or HughesNet in the consumer market.

Which Should You Choose?

If Starlink is available in your area and you can afford the upfront equipment cost, it is the clear winner on almost every metric that affects day-to-day internet use. Lower latency, faster speeds, no strict monthly data caps on the Residential plan, and a steadily growing coverage footprint make it the superior technology.

GEO services retain relevance in a few specific situations. HughesNet and Viasat are available in some areas before Starlink capacity has been added, and their equipment and monthly costs are sometimes lower. If your primary use is standard-definition or HD streaming and you are not gaming or video conferencing frequently, the higher latency of a GEO service may be tolerable and the lower monthly cost attractive.

The most reliable way to evaluate any satellite service once you have it installed is to run a speed test regularly. Latency, download speed, and upload speed together reveal whether your service is delivering what you are paying for and can highlight congestion issues specific to your area or time of day.
