LEO vs GEO satellite internet: what enterprise sites need to know

Key takeaways

• Distance sets the delay: A geostationary satellite sits so far out that every round trip takes about half a second, regardless of the equipment.
• LEO fits interactive apps: LEO satellite's measured US latency is now low enough for calls, video, and virtual desktops.
• GEO still has its jobs: Geostationary service suits one-way broadcast to many sites and traffic that tolerates delay, with wide coverage from few satellites.
• Check the site first: Sky view, mounting, plan type, weather, and peak-hour capacity decide how well satellite performs at a given address.
• Run satellite as one more link: Satellite works best inside the same SD-WAN and security design as every wired and wireless link.

The lag comes from distance, and mines, farms, and depots outside fiber's reach often have few other options. Low earth orbit constellations now serve businesses alongside the geostationary services remote sites have used for decades. Consumer reviews test home service and skip the questions an IT team asks about app performance, SD-WAN fit, and support.

The choice of LEO vs GEO satellite internet comes down to distance. LEO satellites orbit far closer to Earth, so round trips are short enough for voice, video, and virtual desktops. GEO satellites sit much higher, so each one covers a huge area, and every round trip adds delay that apps can feel.

Teams that get satellite right judge each orbit by what the site needs to run. That lets you choose the orbit and plan type for each site and spot the jobs where GEO still wins.

What LEO and GEO mean

Low Earth orbit (LEO) satellites circle close to Earth. ESA describes LEO as normally below 1,000 km, or as low as 160 km, and counts any orbit under 2,000 km as LEO. A LEO satellite circles Earth in about 90 minutes, and continuous service takes a constellation of many satellites.

LEO satellite uses low Earth orbit, Eutelsat flies 600+ OneWeb satellites in 12 orbital planes at 1,200 km, and Amazon runs its system as Amazon Leo, formerly Project Kuiper. LEO satellite and OneWeb offer low-Earth-orbit satellite internet for business.

Geostationary orbit (GEO) sits 35,786 km above Earth, over the equator. A satellite there circles once a day in step with Earth's rotation and appears fixed over one spot. Geostationary satellite internet relies on that fixed position, with each site's dish pointed at one satellite.

Why orbit height changes latency

Radio signals travel at the speed of light. A request from a site goes up to the satellite, down to a ground station connected to the internet, and back the same way. Every leg covers at least the satellite's altitude, so the orbit sets a floor on satellite internet latency before routing or processing adds anything.

Working from ESA's GEO altitude, the propagation floor for one GEO round trip comes out in three steps:

• Four legs: Site to satellite, satellite to ground station, and the same two legs back add up to at least 4 × 35,786 km, or 143,144 km.
• Signal speed: Radio signals cross about 299,792 km every second.
• Round-trip floor: 143,144 km divided by 299,792 km per second comes to about 477 milliseconds (ms), before any processing or routing.

The same math at LEO's usual ceiling of 1,000 km gives about 13 ms. The ITU's G.114 standard (Table A.1) points the same way, with a planning value of about 260 ms one way through space for a satellite hop at 36,000 km.

Real networks add delay on top of that floor. In Ookla's US Speedtest data for Q1 2026, median latency on LEO satellite was 39 ms, and the two GEO services Ookla measured came in at 674 ms and 750 ms. A gap that size shapes which apps a site can run well.

LEO vs GEO at a glance

LEO vs GEO satellite service differs on the lines that shape a site plan, from the delay users feel to the kit on the roof.

The floor figures count propagation time alone. The measured figures come from US consumer Speedtest results, and business plans and other regions can differ.

What latency means for business apps

A site running email and overnight uploads can live with GEO, and a site running calls or virtual desktops needs a lower-latency path such as LEO. Satellite internet latency still varies by region and load, and jitter, the swing in delay between packets, matters as much as the median.

• Voice and video calls: Calls react to both delay and jitter, and they run well at LEO latencies, while GEO round trips add enough lag that people talk over each other.
• VDI and remote desktop: Every keystroke and mouse move waits on a full round trip, so a remote desktop over GEO feels sluggish while LEO keeps the lag small enough for most work.
• SaaS and web apps: Browser apps tolerate more delay, though chatty apps that make many calls per page slow down because each call pays the round-trip cost.
• VPN tunnels and file transfers: TCP throughput on a single connection falls as round-trip time rises, which slows VPN-tunneled transfers over GEO even when the plan has bandwidth to spare.

Where GEO still fits

Geostationary satellite internet keeps a place in enterprise networks. One GEO satellite sees a huge share of the planet, and ESA notes that three evenly spaced satellites can provide near-global coverage. SES, which operates GEO and MEO fleets, positions GEO for broadcast and backhaul across huge regions.

That reach suits one stream sent to many sites at once, such as digital signage, training video, or software updates, because one satellite reaches every site in its footprint at the same moment. One-way traffic like this barely notices the delay, and telemetry and batch file sync can wait it out because nobody watches them run.

GEO has limits at the edges of the map. Satellites parked over the equator don't work well for far northern or southern locations, and high-latitude sites usually look to LEO. Either orbit can also give a wired site satellite as a backup path, a role with its own design questions.

Where MEO sits between them

ESA places medium earth orbit (MEO) anywhere between LEO and GEO, which puts it in the middle of any MEO vs LEO vs GEO comparison. SES runs its O3b mPOWER system there, citing 150 milliseconds of predictable satellite latency across large regions.

What to check before deploying satellite at a site

Enterprise satellite internet performs only as well as the site and plan behind it. Work through these six checks before ordering satellite internet for remote offices or any site where satellite carries the main load.

• Site survey: The terminal needs a wide, clear view of the sky, and LEO satellite notes that highly obstructed views reduce performance; its app builds an obstruction map that can take up to 12 hours. Include trees and roof equipment that change through the year.
• Mounting and kit: Plan the mount, cable run, and power early. LEO satellite lists a 140° field of view for its Performance kit against 110° for Standard, and Standard needs an extra power supply to work with third-party routers.
• Plan type: Business plans differ from consumer ones on public IP, network priority, and support. LEO satellite's Priority plans include prioritized network access, a public IP, and priority support, and Priority data expires at the end of each billing cycle.
• Weather: Heavy rain weakens higher frequency bands, and ESA describes Ka-band as sensitive to rain. LEO satellite warns that heavy snow covering the dish can interrupt service, so mounting height matters at cold sites.
• Capacity: Ask the provider how service behaves at peak hours in busy areas. For speed context, Ookla found that 44.7% of US LEO satellite Speedtest users met the FCC's 100/20 Mbps broadband benchmark in Q4 2025. Size each site's plan from tested busy-hour speeds.
• Cost: Budget for the terminal and mount, the service tier, and any priority or pooled data, then compare the total with a wired build.

Run the same comparison against fixed wireless where signal is strong, since a nearby cell site can make satellite unnecessary.

Satellite inside a multi-site network

Satellite rarely runs alone in a multi-site network. At sites with no wired access, LEO can serve as the primary link. At sites with fiber or cable, it can share the load with the wired circuit every day. There, an SD-WAN edge steers each application to the best-suited link, and calls and virtual desktops ride the lower-latency path.

Planning access types by site across every location keeps satellite in the role where it performs best. It also puts LEO satellite connectivity for remote sites under the same multi-site connectivity design, routing, and security policies as every wired and wireless link.

Security belongs in the same plan. A satellite site needs the same policies as a branch on fiber, and bringing scattered sites under one SASE design applies those rules wherever traffic enters the network.

Connect the sites the fiber map leaves out

Orbit sets the latency floor, and that floor shapes what a remote site can run.

When it comes to LEO vs GEO satellite internet, LEO's shorter path fits interactive apps, and GEO still fits broadcast and traffic that tolerates delay. Each satellite site still adds a link to plan, monitor, and support the hardest-to-reach locations when something breaks.

FAQs

Is LEO satellite LEO or GEO?

LEO satellite is a LEO system. LEO satellite describes its network as a satellite constellation in low Earth orbit, which is why its measured latency sits far below geostationary services. A LEO satellite terminal follows satellites as they cross the sky, while a GEO dish points at one fixed spot.

Why does GEO satellite internet have high latency?

GEO satellites orbit 35,786 km above the equator, and every request and reply travels four long legs between the site, the satellite, and a ground station. At the speed of light, that path alone takes about 477 ms per round trip. Better equipment can't shorten it, because the delay comes from distance.

Is LEO satellite internet good enough for video calls?

Often, yes. Ookla measured a US median latency of 39 ms on LEO satellite in Q1 2026, low enough for video calls. Results vary by region, time of day, and how many users share the area. A trial at the site shows how calls hold up at busy hours.

What is MEO satellite internet?

MEO satellite internet uses satellites in medium Earth orbit, which ESA places anywhere between LEO and GEO. Sitting higher than LEO gives each satellite a wider footprint, and sitting lower than GEO shortens round trips. SES, which runs the O3b mPOWER MEO system, cites 150 ms of predictable latency across large regions.

Does weather affect LEO satellite internet?

Yes. Heavy rain weakens higher-frequency bands such as Ka-band in any orbit, and LEO's shorter path doesn't remove that effect. Sky obstructions and snow cover also interrupt service. LEO satellite notes that heavy snow covering the dish can cause intermittent or temporary service loss, which makes mounting position matter at cold sites.
