We often get asked how many satellites are in orbit, or about their current operational status. Sometimes, the questions are deeper, and users might want to know about the satellite signals, or the services they provide. Adding complexity to the subject is the fact that GNSS satellites are always in flux, often being updated, and – sometimes – failing.

We are happy to provide these answers and references to each of the major global and regional constellations. We encourage you to use this information in tandem with our GNSS Spectrum poster.

If you have any questions, we encourage you to join the Skydel User Forums.
