Hello. I'm starting with a Resolution T, which claims to offer a single-satellite mode. I gather that it's not an amazing receiver, but I'm hoping it will be good enough for a first foray at least. I'm rather hoping that it will do well, though, since it would mean a cheapish way of making a self-contained device with 10MHz/ANT on one end and Ethernet on the other.

About the only way around that is to pre-determine a set of sats and flag the rest as "do not use". With the second approach, various geometric issues can get a bit exciting. Either way good antenna locations and local clocks are needed. Do you have a specific receiver in mind?
