Five Misunderstandings About Car GPS
Misunderstanding NO. 1: privacy violatedMany worried that if they use a GPS device, their car could easily be tracked by government and their privacy are violated. A little common sense of how GPS devices receive signals would disperse the misconception. As Wikipedia says about it,ň€ś (GPS) uses a constellation of between 24 and 32 medium Earth orbit satellites that transmit precise radiowave signals, which allow GPS receivers to determine their current location, the time, and their velocity.ň€ť Although some commercial grade GPS devices send out signals about your whereabouts, consumer car GPS devices sold on the market only receive signals sent from satellites. Government has no interference with the car GPS signals and would not have any idea about our whereabouts.
Misunderstanding NO.2: weather influence
It is true that such fierce weather conditions as thunderstorm, lighting, or hurricane would have influence on the signal receiving of car GPS devices, just as TV and radio signals would be unstable under such fierce weather. However, cloudy and rainy days would do no harm to the performance of your car GPS device. The same GPS technology is used in aviation system, and airplanes can still get through clouds. Itň€™s the same case with car GPS system.
