Friday, June 10, 2016

It is not easy to get the best radar detector, for example, if you want to buy a Valentine One V1, apart from reading its detailed information in many Valentine One V1 reviews or comparisons between it and the others, it is essential to get knowledge about radar guns. It seems rather easy to say but in reality, you will know how hard it is. In the previous part, we have explained to you the radar gun which is also the traditional type to find out the over-speed vehicles. To be continued, this part will show you how it works. 

The principle of operation of radar guns

A speed gun is just basically a receiver - transmitter radio. That generator it makes oscillating electric current makes the high voltage at a low moment in a certain frequency. Since then it generates an electromagnetic energy and currents fluctuate when that energy is released into areas like the electromagnetic waves. Such a transmitter amplifier also raises an antenna as well as an electromagnetic energy to widen it out into the atmosphere. What the receiver is used to record the signals emitted from the transmitter above. It recorded the electromagnetic wave antenna with a signal and then converted into an electric current.
Radar can also be used to calculate the speed level of a vehicle due to a principle named the Doppler shift. The basic principle is that the device will send microwave signal (s), when the signal having your car it will come back to the device. In cases your vehicle moves the signal which has sent out and now then it returns to the gun to help measure the Doppler to understand whether or not your car is driven at a high speed. Like sound waves, radio ones have a certain frequency as well as oscillations counted in a time unit. When the radar guns as well as the car all stands still, the signal received on the similar frequency as the original one. Feedback signals when facing an obstacle will be returned with the same exactly the same signal.
In order to calculate that with high correctness, the signal is sent out to be power enough so that when it hits your car, it can be reflected back to the gun. A radar detector is designed to alert the speed gun police are near you. A radar signal can catch it as soon as we are not strong enough to return to the gun, which can be time enough for you to reduce speed to avoid getting the small round holes on the driving license.

GPS is a system consisting of satellites flying in orbit, collecting global information and processed by the control station on the ground. GPS satellites circling the earth two times a day in a very transmit signal and precise orbit information to the receiving device. The GPS receiver receives that information and using trigonometric calculations, calculate the exact position of the user.
Importantly, the GPS receiver makes comparison the time a transmitted signal through a satellite and the time to get them. The misconception about time that the device how far the satellite in the way. Now, with distance calculations from some more satellites, the device is able to determine the position of users and the position has been located, the computer software will continue to compare with the corresponding coordinates on the map from providers such as Google, Yahoo, Microsoft, BlackBerry, ... and then locate the user's position on a map that displays numbers and information on the screen.


Thus, on the way to work, all GPS navigation devices have to work the same way, however - says the key to the strength / weakness of a GPS is accurate as well as space it supports.

To choose a good car GPS, it is recommended to consult many car GPS Reviews as they will help you get more useful information.
