Parking GPS synchro
Date time synchronisation for parkings via GPS
Correctly synchronised date and time are of crucial importance in time-based parking systems. A GPS receiver synchronises the UTC (Coordinated Universal Time) time. Local time is then calculated from this.
Operation:
The GPS (Global Positioning System) consists of 24 operational satellites that orbit the Earth in six fixed paths, each satellite transmitting its own signal. The system operates 24 hours a day and covers practically the entire globe. Under ideal conditions, from 5 to 10 satellites will be visible at any one time.
Environmental conditions can play a major part in the number of satellites from which data can actually be received, however. Disruptive factors can include: high buildings, steel structures and wooded surroundings, as well as weather conditions such as rain, snow and fog. The internal clock compensates for these effects.
