GPS system consists of antenna, LNA, SAW filter, RF front-end GPS and GPS Module including crystal oscillators Fox, Fox RTC crystal frequency of 32.768 KHz with, and PIC (low dropout) regulator.

Antenna: – energy is transferred to signals from the transmitter in space with the distribution and efficiency required. It also measures the exact address.

Low noise amplifier (LNA): – A special type of electronic amplifier that amplifies the weak received signal by the antenna and to reduce noise in the received signal as well. They are often placed near the antenna to minimize losses occurring in the line of feeding coaxial cable, because it's loss at microwave frequencies.

Filter surface acoustic wave (SAW): – received SAW filters amplified signal of low noise amplifier and fed to the GPS RF Front-End. These electromechanical devices in which electrical signals are converted into a mechanical wave in a device constructed of a piezoelectric crystal or ceramic.

GPS RF Front-End: – Front RF is a generic term that is in a receiver that sits between the antenna and the intermediate frequency (IF) stage.

GPS Module: – Includes Fox crystal oscillators, crystal often RTC 32.768 KHz and a PIC (low dropout) regulator.

Few FOX series are used as a TCXO in GPS application as FOX923GP, FOX914 and FOX312BE series because of sine production cut, the stability of 0.5 ppm and 1.8 to 3.3 voltages.

FOX series are used as an RTC crystal, applying GPS as FX255, FX145 and FX135 series due to the long-term stability and frequency of 32.768 KHz.

Fox's products are used in GPS product applications are RoHS Compliant.
