Inmarsat Coverage and Coverage Maps

Inmarsat owns and operates 13 geostationary satellites. They continuously orbit over 22,000 miles above Earth staying in line with the equator. Each satellite fleet utilizes a mix of wide beams and narrow spot beams to ensure overlapping coverage around the globe. At this time (and you can see this on the coverage map visual), the polar regions cannot be reached by way of the current satellite setup. But Inmarsat’s fully funded technology roadmap includes reaching the polar regions within the next few years.

You can read here for an in-depth overview of Inmarsat’s entire network of satellites and how they operate to offer coverage.

Are there any cons of using the Inmarsat service?

Though Inmarsat is one of the top of line choices in remote and portable satellite communication, it is lacking in one main area.

Unlike its competitor Iridium Satellite Network, Inmarsat’s service is unable to reach the polar regions. This is due to the difference in both the number of satellites in operation as well as how and where they operate. Inmarsat utilizes 13 geostationary satellites 22,236 miles above the ground, whereas Iridium maintains 66 satellites that surround earth at a much lower altitude.

So, why does Inmarsat’s network not cover the polar regions?

Geostationary satellites, which is how Inmarsat’s network functions, always remain at the same spot over the earth – directly in line with the equator. Though this type of operation covers almost the globe by way of 13 operational satellites, the poles, unfortunately, are inaccessible. (Though arctic capability integration is in the works as a future enhancement.)

So, if you require pole-to-pole connectivity no matter what, Iridium is your go to. On the other hand, many users won’t require service in these two points of the world and can turn to Inmarsat for reliable communication everywhere else (and at a lower price point).
