While Amazon has revealed few technical specifics so far, FCC filings indicate Kuiper will utilize Ka-band frequencies for increased throughput. Its LEO satellites whizzing 550 km above Earth will minimize latency compared to traditional satellite internet constellations.

Amazon expects to invest over $10 billion into Kuiper. And as one of the world‘s most customer-obsessed companies, they aim to make satellite internet affordable, reliable and user-friendly on a global scale.

But can the new kid on the block compete with established experts like Inmarsat?

What is Inmarsat?

While Amazon is just getting its rockets ready for liftoff, Inmarsat has been pioneering satellite communications since 1979. This British company focuses on global mobile connectivity solutions for maritime, aviation and government users.

Let‘s get to know this satellite veteran:

  • Originally created to provide maritime safety services
  • Currently operates 13 satellites in geostationary orbit 35,000 km up
  • Primarily uses L-band and Ka-band frequencies
  • Experience supporting critical operations and IoT
  • Network of value-added partners to deliver specialized solutions
  • Trusted provider for governments and global enterprises
  • Committed to ongoing investments in new satellites

Inmarsat may not be a household name like Amazon, but it‘s been powering vital communications worldwide for over 40 years!

In that time, Inmarsat has built an extensive ground station network and cultivated key partnerships in industries like maritime and aviation. It knows how to tailor satellite offerings to the needs of international corporations, aid agencies and the public sector.

While Inmarsat also offers broadband services like BGAN, it focuses more on guaranteed reliability and mobile connectivity than raw speed. But decades of experience brings trust and expertise new players will struggle to match.

Now that we‘ve gotten familiar with both these satellite internet services, let‘s see how they stack up!

Comparing Kuiper and Inmarsat Head-to-Head

Amazon Kuiper Inmarsat
Founding Year 2019 1979
Headquarters Seattle, USA London, UK
Orbit Type LEO GEO
# of Satellites 3,236 planned 13 currently
Max Speed Up to 1 Gbps Up to 400 Mbps

With their different histories and technological approaches, you might think one is clearly superior. But which service "wins" really depends on your specific needs! Let‘s break it down.

Low Earth Orbit vs. Geostationary Orbit

One massive difference is Kuiper‘s use of low Earth orbit (LEO) satellites versus Inmarsat‘s geostationary orbit (GEO) satellites.

LEO satellites orbit around 550 km up and complete a lap around Earth in just 90-120 minutes! Because they‘re closer, transmitting signals to the ground takes less time. This really minimizes latency.

But LEO satellites zoom by fast. So to have continuous coverage, you need many satellites working together as a "constellation." SpaceX‘s Starlink uses over 2,000 satellites alone!

GEO satellites are positioned at an altitude of 35,786 km directly over the equator. At this high vantage point, they exactly match Earth‘s rotation, remaining parked above one spot.

Just 3-4 well-placed GEO satellites can see 1/3 of the world! But the much farther distance leads to higher latency of 500-600 ms versus 20-40 ms for LEO.

So in summary:

  • LEO = Lower latency, needs many satellites
  • GEO = Higher latency, only a few satellites needed

For consumer internet, LEO clearly wins on responsiveness. But GEO works well for coverage over high traffic areas like shipping lanes.

Speed and Performance

Amazon is marketing Kuiper as a high-speed broadband service capable of 400 Mbps and up. While actual speeds remain to be tested, Kuiper‘s use of Ka-band frequencies, bleeding-edge satellites and proximity to Earth give it an edge.

Inmarsat‘s GEO satellites employ L-band and Ka-band for reliability and mobility applications. The BGAN service offers max speeds around 400 Kbps – useful for web browsing but not streaming HD video.

However, Inmarsat knows latency and jitter matter more than raw bandwidth for uses like navigation and critical communications. Not every customer needs or wants to download movies from space!

But there‘s no question Kuiper aims to provide fiber-like speeds that far exceed most existing satellite internet providers.

Intended Users and Use Cases

One area where the services clearly differentiate is their target customer base:

Amazon Kuiper will market direct to everyday residential users who just want simple, affordable high-speed internet without cable or fiber access. Think rural households, isolated communities.

Inmarsat focuses on industries like maritime, aviation, government and global enterprises. Users that value mobile connectivity and reliability over lightning fast Netflix.

Let‘s look at some example use cases:
