Satellites play a very large role today, perhaps unnoticed or unappreciated, I guess, and they are all what are called geostationary satellites. They do provide service. Today, they provide television, telecommunications, GPS and so on.
A lot of the discussion today is about the low-earth orbit proposals or the systems that are being built. Indeed, they hold a great deal of promise, as they are a substitute for fibre and can provide low latency and high throughput services to individuals who aren't close to the traditional points of presence of telecommunications providers.
