Hmm…I guess some have network selection menus, but do those that don’t, e.g. Wahoo Bolt, which claims to use 5 networks, switch automatically between the GNSS options? I’d assume it picks which system to use based on the number of satellites visible, and would not expect that any use two different systems at the same time; how would they rectify the signal data (i.e. decide which system is correct)? My guess would be that chipset, processing speed and capacity, and power usage would be factors determining whether a computer limits satellite search to only a couple networks, or automatically searches for the most robust network from among all those it can use.
I know this is a little OT, but this is also an extra geeky GPS question!
