Explanation:
- Each GPS satellite consist of the multiple atomic clocks that contribute to the precise time and data to the GPS in the signal forms and this data is decoded by the serves of the GPS satellite and shows an effective synchronization and each receiver and precise time is accurate and has a variety of activity around the world.

It allows people to spread their brands globally as they can be able to monitor them more easily through communication. It is also easier for traders to exchange and collaberate. Much business chances are provided hense increasing the trading over the world.
Hope it helps!
