Working Principle

The working principle of GPS-622R is based on the principles of radio-frequency (RF) wave propagation. The receiver uses an antenna to capture RF signals of a given frequency range within its operational bandwidth. The signals are then amplified and filtered before being processed by the receiver. The received signal is then mixed with an internally generated signal of a known frequency. As a result, a difference frequency is produced which is proportional to the wavelength of the input signal. This difference frequency is then demodulated and reduced to a level that can be detected and measured by an analogue-to-digital converter. The resulting digital signals are then processed by the receiver for further analysis.

Conclusion

GPS-622R receiver is a type of RF Receivers used for a variety of applications such as communications, navigation, remote sensing, radar and remote measurement.
