+28dBi GPS Antenna - improves Signal-to-Noise Ratio in satellite signals reception and position accuracy

As you probably know, the Global Positioning System (GPS) is a satellite-based radio transmission system for locating any position on earth based on triangulation data obtained from three to eight satellites. With multiple measurements, GPS can calculate speed and direction as well as store the path you used to get to where you are so that you can make a return trip.

The system was launched for the U.S. military, and is still used for that purpose. GPS is a very sophisticated system, and can locate objects to within a few feet of their position.

You can easily add GPS to any car by using portable GPS devices from different manufacturers. The major difference between them is really the chipset they use that also affects the price, size, cord (USB2.0) or cordless (Bluetooth), the number of satellite tracking channels and battery power consumption. The Bluetooth GPS receiver showing in the picture is using the latest SiRF III chipset with 20 tracking channels. It is connected to an amplified GPS antenna for improving the signal-to-noise (SNR) Ratio in satellite signals reception and position accuracy driving in the urban area.


    The +28dBi Amplified GPS Antenna:

Most GPS receivers are compatible with MMCX or MCX RF connectors for external antenna termination. You may look up your GPS receiver manual or ask danets for matching details.

    The GPS Devices:

If you are new to GPS navigation, here are some installation tips. You can easily add GPS to any car by buying a GPS receiver from one of several different brands, such as Garmin, NAVMAN, Holux, Global Sat and Magellan. These devices can be portable and are meant not only for cars but for backpacking as well. There are three main types GPS devices: (1) the fully integrated handheld GPS device that includ es the GPS receiver, color display, software packages and maps; (2) the GPS receiver with USB2.0 cable; and (3) the Bluetooth GPS receiver.

The handheld integrated GPS device can run from $400 to $2,000 as a standalone handy solution, whereas GPS receivers cost much less with the flexibility to work your laptop or PDA. The Bluetooth GPS receiver is becoming the most popular one because of its low entry price barrier and it could pair up wirelessly with other Bluetooth computing devices.

    Adding GPS to Laptop and PDA :

If you have purchased a mapping program such as Microsoft Streets and trips, Rand MCNally's StreetFinder, or Delorme Street Atlas USA, you may have noticed that these packages can read the signals from GPS receivers. You can also find ample shareware and freeware in this category. A search on Download.com for the word "GPS" returns many listings for your reference.

For the most part, adding a GPS receiver to your laptop or PDA is as simple as installing the necessary drivers and plugging the device into your computer. Most GPS devices are Bluetooth or USB connected, although earlier models were more often serial port devices. You'll probably find the GPS receiver you purchase comes with one of the software packages mentioned above. When buying devices like these, try to make sure that they conform to the marine standard so that they are broadly compatible.
