The Importance of Having Multiple Sources for Satellite Tracking

The terrestrial network I think really maintains is the heart of what we do and it will remain so for a very long time. Could you imagine that a satellite could actually replace the terrestrial network at some stage? We need to have the ability to collect from multiple sources, especially when you're collecting radio signals. And it also provides a checksum of sorts on the ADSB data coming either from the terrestrial network or from a space network.
