The new services are set to use satellites in low Earth orbit. That only adds a few hundred miles to the distance your data has to travel. The added latency is measurable, but not very high. The problem with existing high-speed satellite internet is that the satellites are all in geosynchronous orbit, which is about 22,000 miles up. For a roundtrip, your data has to go up to the satellite, down to the ground station, then back up to the satellite and back down to you, for a total of almost 100,000 miles, or more than half a second at the speed of light. |
