GPS Timing antenna technical requirements

It`s to receive GPS satellite signal some special requirements are as follows:

The main difference between the timing antenna and the ordinary antenna is that the timing antenna should work continuously and reliably for a long time to reduce the influence of the environment. Therefore, the timing antenna and the ordinary antenna are very different in design, and it is necessary to focus on the lightning protection design , Stability design, anti-jamming design.

The timing GPS antenna is a solid, L1 antenna designed for a variety of applications with superior performance. It contains superior multipath mitigation measures. Antenna can withstand severe weather and harsh environments. The timing GPS antenna has a high stability phase center, providing flexible antenna mounting and placement.

Technical Specification for Timed GPS Antenna Installation .

Before the installation of the antenna, the strong requirements in the user first GPS test, after the normal access to confirm the GPS and the antenna without any quality problems, and then upstairs or base station installation, in order to correctly determine whether the installation problem caused by the antenna can not be used normally The

Installation specifications:

1, check the appearance of GPS antenna is normal, the interface is correct.

2, GPS antenna connector requirements with the host and antenna mushroom head plug firmly.

3, GPS antenna and the connection between the host line requires concealed laying, and to ensure that through the site without sharp and can impact objects, do well rodent measures to ensure that the cable is not due to external factors.

4, the installation process is strictly prohibited part of the external pull connector, which can easily lead to the joint line or connector to shrink the phenomenon, affecting the normal use.

5, to ensure that the GPS antenna installed horizontally up and down, and has not been blocked.

6, GPS signal because it can not penetrate the metal and building objects, must be installed in the sky to see the location, and requires broad vision, that is, full view, so as to receive as much as possible satellite data, only received more than 4 satellites Data, GPS module can output valid pulse data.

7, GPS antenna is shielded, too close to high-rise buildings, the antenna location is not installed properly, antenna patch contact bad, external pull, rat bite and other factors will cause normal pulse output problems.
