GPS-Антенна top2 для TR 641-644 top2, Sel171 top2 RC, Lu121-122top2

GPS receivers enable global positioning. As every satellite
continually transmits UTC time (Greenwich Mean Time) via an
atomic clock, it can be received worldwide.
The top2 RC GPS antenna receives position and time signals
from GPS satellites and passes them on to time switches. The
exact local time is calculated in the time switch according to
the set time zone.
