About External GPS Antenna Factory in China--Long Praise

GPS antenna is through reception of satellite signals for locating or navigation terminal.
And you must use the signal reception of the antenna. GPS satellite signal is divided into L1 and L2, the frequency of 1575.42 MHz and 1,228 MHz, respectively, to open the L1 civil signal, the signal for circular polarization. Signal strength is about 166 - DBM, belongs to the weak signal. These characteristics determine the necessity of the GPS signal receiving antenna.
GPS antenna - the classification of the GPS antenna
1.from polarization mode, GPS antenna is divided into vertical polarization and circular polarization. In today's technology, the effect of vertical polarization than circular polarization. So in addition to special circumstances, the GPS antenna will adopt circular polarization and linear polarization.
2. GPS antenna is divided into a built-in antenna from the placement and external antenna. The antenna assembly position is also very important. Early GPS handsets with eversion antenna, the antenna and the whole machine internal basic isolation, almost does not affect the EMI, star effect is very good. Now, with miniaturization trend, with built-in GPS antenna. The antenna must be above all metal components, shell plating and good grounding, away from the EMI interference sources, such as CPU, SDRAM, SD card, crystals, DC/DC. The application of GPS will be more and more common. The car shell, especially the car explosion-proof membrane can produce serious hinder GPS signals. A gps antenna with magnetic is very necessary now.
3. From power supply ,GPS antenna is indiveded into active antenna and passive antenna. External GPS active antenna, for example external vasco GPS antenna is basically belongs to the active antenna. Passive antenna is not including antenna LNA amplifier, only antenna ontology.
