The differences between external GPS antenna and GPS timing antenna

The differences between External GPS Antenna and GPS timing antenna
For receiving GPS satellite signals,there are special requirements as follows:

The main difference between them : timing antenna should work continuously and reliably for a long time, reducing environmental impact, therefore, timing antenna and ordinary antenna design has a big difference, we must focus on mine design considerations stability design, anti-jamming design.

GPS timing antenna is designed for a variety of applications, we have superior performance, solid L1 antenna. It contains superior multipath weaken measures. Antenna can withstand severe weather and harsh environments.  GPS timing antenna phase center there is a high degree of stability, providing flexible antenna installation and placement.

GPS timing antenna mounting technical specification
Before the formal installation of the antenna, user are required to perform GPS test, the normal pulse signal obtained confirm the GPS and antenna without any quality problems, and then go upstairs or base station installed in order to properly determine whether it is due to the problems caused by the antenna can not be installed Normal use.

Installation specifications:
1, the GPS antenna appearance inspection is normal, the interface is correct.
2, GPS antenna connector and antenna requirements and host mushroom head firmly seated.
3, the connecting line between the GPS antenna and the host requirements lay hidden, and to ensure that there is no sharp line through which parts of the body and severe impact, good rodent control measures to ensure that the cable does not disconnect because of external factors.
4, the installation process is strictly prohibited external pull tab portions, this can easily cause the feeder and connector or connector pins appear string line back out of the phenomenon, affecting the normal use.
5. Make sure the GPS antenna mounted horizontally mushroom head facing upwards, and has not been blocked.
6, GPS signals can not penetrate metal and building because objects must be installed in a position to see the sky, and requires vision, that whole vision, so as to receive the satellite data as much as possible, only received more than 4 satellites data, GPS module can output a valid pulse data.
7, GPS antenna being shielded, too close to the high-rise buildings, install the antenna position is incorrect, poor contact patch antenna, external pull, rat bites and other factors may cause the normal pulse output problems.
