Block Diagram of GPS Active Antenna
GPS (Global Positioning System) is a satellite-based navigation system. In an unobstructed clear
view of the sky, GPS works anywhere in the world, and 24 hours a day.
GPS is developed and operated by the government of United States. Under the policy of the
government, the degradation in accuracy shall occur without prior warnings, and sometimes
satellites don’t transmit signal due to adjustment, test, and orbital revision.
Also, please note:
1. Products such as motors, computer, and RF devices, which emit high levels of magnetic field
and interference, that may cause the performance of the GPS unit to drop.
2. The optimal position during automobile applications is on the roof top of the vehicles. If the
GPS antenna unit is to be placed inside the car, be certain to avoid coverage by metal objects for
optimal performance
