The day is fast approaching when Global Positioning SystemsGPS will be as important accessory as an AM/FM/CD player. Not only can your vehicle GPS be an important navigation tool, but it is also a safety device. Many units such as the Garmin Nuvi GPS provide Bluetooth connectivity with your Bluetooth capable cell phone, offering your hands freedom from the cell phone, which is becoming a mandate in many states. Also, Personal Navagation Devices provide traffic advice on delays ahead and offer alternative routes to your destination. Tired of listening to the radio, load your favorite mp3’s on a SD card and listen to them instead. eBooks can also be put on SD cards. Also, never get lost in the woods again with that GPS Handheld . You'll find some of the Best GPS Handheld units here as well as the Best Garmin GPS units. Also, some Garmin Nuvi GPS units are now made to be carried on your person. Global Positioning Systems GPS has found it's way into Radar Laser Detectors . GPS locations are being used in Radar Laser Detectors to notify the vehicle driver of upcoming law enforcement locations. Examples or these type of units are the Beltronics Radar GX65 and The Escort Detector 9500IX . Both of these as well as the Cobra XRS9960G are fine GPS Radar Detectors . They are similar to having a GPS with Radar Detector combination.
Wonder how a Highway Patrol Car’s Radar Laser Gun Works?
Police cars operate by transmitting a signal on a radio frequency and receiving that frequency signal back.Laser Radar transmits light. This is what allows a Radar Laser Detector to work as a receiver for the particular operating frequency of the unit mounted in the police car. It’s the time between the transmission and the reception at the patrol car that determines the speed of the target vehicle. The Laser Radar Detectors are merely receivers for the “Gun” in the police car. If both the patrol car and the target vehicle are moving, there is a measurable change in frequency that occurs that in turn is translated into a shift into miles per hour and thus determines the speed of the targeted vehicle. This frequency shift is called Doppler shift. This doesn't apply to Laser Radar . Laser Radar has to be aimed at a reflective surface on your car like a front lisecne plate or headlight.
Police Radar transmitters operate in 3 different bands, X Band, 10.525 GHZ, K Band, 24.150 GHZ, and Ka Band 33. 4 to 36.0 GHZ. Most units be in used today patrol cars are either the K-band or the Ka-band. X is still use but by a very small number of departments. That’s why it’s still built into the receivers of the Radar Laser Detectors . Police Laser guns are a different device altogether. Laser transmitters have to be used in a stationary position and aimed at a flat surface such as a front license tag or head light in order to reflect the signal back to the gun to determine the speed. The good news for the Laser Detector is that the angle between target and gun can’t be more than 20 degrees or the accuracy could be way off. Also, this is another reason you usually don’t see laser operated from the rear of the target. I’ll also mention here that there are available Radar Jammers , but please check the laws of your state to make sure they’re use is legal. Now new to the Radar Laser Detector category are the new GPS units. These units keep a data base of all fixed camera (red-light and speeder - Photo Radar ). All of the popular brands, such as Escort Radar Detectors , CobraDetector, Beltronics Radar , and WhistlerDetector can all be found right here at BestGPSRadarDetectors.com!
