Precise GPS coordinate application
The precision you need when collecting location data depends on the GPS jammers you're dealing with. When collecting location information using a device's location services, location information can be determined from a variety of sources, such as GPS, cellular, Wi-Fi, or Bluetooth networks. The accuracy of these sources varies, so the device's location service is not always reliable. Professional-grade or high-accuracy GPS receivers are often the best choice for those performing data acquisition that requires greater accuracy and reliable quality control.
High-precision GPS receivers use information from GPS satellites to accurately calculate geographic location. The accuracy of these receivers ranges from sub-meter to centimeter levels, depending on their ability to track and process satellite signals. GPS satellite signals are transmitted on different frequencies. The more frequencies a GPS receiver uses, the more signals it will receive, and the more accurate it will be.
