Does having all these additional satellites make our location more precise? Or it’s up to dual-frequency?
In: Technology
They can use multiple systems at the same time. More satellites result in a more accurate position, primarily when you move around and object close to you can block the signal from some of the satellites.

You phone doesn’t even use the satellites, except in rarer cases, such as no signal from your mobile network. It only needs to look for the satellite signal when all else fails. Think of the satellites like a backup option.
Most phones actually get location data and the satellite data from the mobile network (the mobile networks sends it directly to the phone), NOT from the satellite itself. Phones and many software are designed to interpret location data from whatever sources are available to them, usually meaning multiple sources and other location data that most certainly are not satellites. But yes, you can program software to get location data from multiple sources and multiple satellites for *potentially* (not guaranteed) improved accuracy.
it depends on the specific device. most modern receivers can use 2-3 systems simultaneously, but not more. especially older ones will choose a single constellation that is ideal for the region (different systems are ideal in different locations)
