4.2 Network Synchronization Message Flow
The indoor SPI-2210 uses GPS for the system synchronization. The UCCM of the MMA-S,
which is the GPS reception module, creates the clock with the clock information received
from a GPS and then distributes the clock to each hardware module in the indoor SPI-2210.
