The radar detector such as that used to exist has been banned since January 1, 2004. These are radar detectors that capture the signals from the cameras and promptly report an operating speed or red light control. Not long after the ban on these detectors has designed a new type of radar detector. These radar detectors work based on GPS. The technology of these these legal radar detectors improves and they can even warn of mobile traps. The radar detector that existed is hardly used for the year 2004. The penalties for the possession of such a radar detector do not lie. There even drive some cars of police around which are fitted with equipment which can detect a radar detector from the old school when it is used in a passing car. After January 1, 2004 there is a new generation of radar detectors designed to operate on the basis of GPS. Initially warned that radar detectors for fixed speed traps but today there are devices on the market even warn of mobile speed. How do these radar detectors and they are really legal everywhere?
Rotate around the earth at an altitude of approximately 20,200 kilometers a large number of satellites. Every 24 hours they lay off orbiting the Earth. These satellites all transmit a radio signal. A GPS receiver receives the signals transmitted by these satellites. A GPS receiver can in response to the signals that it receives to determine very accurately where the device is exactly situated. Use is made of the position of the satellites, and one combination of the distances from multiple satellites to the receiver. Besides the positioning also possible to calculate precisely how fast the GPS receiver, so the hard drive the car at the time.
GPS is very accurate but the place that indicates the receiver can vary from 1 to 25 meters from the exact spot where the recipient is located.
The best known application of GPS is the navigation system that many road users present in the car, on the engine or on the bicycle down. Even hikers have instrumentation for. In addition there are more and more mobile phones made by a built-in navigation system.
There are several ways to be alerted when approaching a speed trap. When the speed limit is not exceeded, for example, can only be given a visual warning, so without a sound. If there driving hard when approaching a speed trap there will be in addition to the visual alarm will sound a sound that continues until the speed is reduced to the maximum applicable speed on that road.
There are types of detectors in addition to the database permanent controls also receive real-time data on known mobile controls at that time what the chances of a traffic ticket for speeding reduces again.
After updating the radar detector can be simply placed on the dashboard of the car and the device is ready for use.
One of the manufacturers who offer good quality equipment is Inforad. This manufacturer has little radar detectors of good quality and the updates are always free. The updates include fixed checkpoints and any previously known controls. Because the update via the PC is no supplements added to the database during the trip. Furthermore Inforad a good, inexpensive detectors able to make without too many bells and whistles. They do well what they should do and that is to warn in an audit.
Another supplier of these devices is Quintezz. This manufacturer has, inter alia, a detector that makes use of TMC. This means that the receiver while driving is updated with the latest information about mobile controls.
Stinger also provides a system to warn you of speed traps. The price though which uses Stinger is a bit on the high side but you do have value.
There are several manufacturers who sell radar detectors based on GPS. They are available in many different sizes and with different features. The purchase prices vary widely. An important point to take in deciding which to buy radar detector is also the price for downloading updates.
