Frequently asked questions
Is GLONASS a device brand?
No. It is a satellite navigation system, just like GPS. A device saying GLONASS is not better on its own.
Does it add anything in Latin America?
Practically nothing over a GPS-only device. It counts at high latitudes and in its home market.
Which devices speak this protocol?
The SL Mini, SL Pro and Mayak, from GLONASSsoft.
