Why Geostationary Satellites Cannot Serve the Poles

The answer is because at high (or low) latitudes the satellite is on the hozizon.

This is because the earth is of course round, so seeing the satellite from the ground based satellite dish, lowers as you get further away from the equator.

Therefore you eventually get so far from the equator, that the satellite is on the horizon, or below the horizon.

Therefore the dish doesnt have a direct line of site path to the satellite.

OpenCPI Explained for Non-Technical People

OpenCPI, for non-technical people, is best understood as a way to build and manage modular data-processing assembly lines – especially for radios and sensors – without having to rebuild everything whenever hardware or requirements change. It helps engineers break complex systems into reusable components, connect them into pipelines, and deploy them across different computing environments more reliably. The reason organisations care is not just technical elegance; it’s practical: fewer integration headaches, more reuse, and better adaptability when platforms shift. If you can picture LEGO bricks snapped into a conveyor belt system that can run in different factories, you’ve basically got it. And if you ever hear someone say OpenCPI helps “portability” or “component reuse,” now you’ll know they mean: build once, plug together, and move with less pain.

What D2D Satellite Means for UK Emergency Services and the ESN

In January 2026, the UK Space Agency issued a request for information on behalf of the Home Office’s Emergency Services Mobile Communications Programme. The question it was asking, in essence, was whether direct-to-device satellite technology could help solve a problem that has been building for more than a decade: the Emergency Services Network is still not ready, Airwave is still running, and rural and coastal coverage gaps remain unresolved.

Can D2D Satellite Replace Mobile Coverage in Rural Areas?

It is one of the most searched questions about satellite communications right now. Direct-to-device, or D2D, satellite services are live in the UK, real operators are offering them, and the marketing narrative is compelling: satellite coverage everywhere, on your existing phone, no specialist hardware required. For anyone who has stood in a field in rural Lincolnshire or on a hillside in Scotland watching the no-signal indicator on their phone, the promise sounds significant.
