(Summary description)The function of the GPS receiving antenna is to convert the electromagnetic wave energy of the radio signal emitted by the satellite into a current that can be picked up by the receiver electronics. Therefore, the size and shape of the GPS antenna are very important. They determine the ability of the antenna to obtain weak GPS signals and the stability of satellite signal reception.

Common types of GPS locator antennas are built-in and external. Compared with the two, which one is better?

The internal and external antennas are well understood in appearance. The built-in GPS antenna means that the antenna is inside the device, and the device and antenna are integrated; the external GPS antenna means that the locator has an external GPS signal antenna, the device and the antenna are separated, and the locator is composed of the host, signal line, and power line.

So, apart from the difference in appearance, what is the difference in performance between the two?

1. Built-in GPS antenna

Generally speaking, the internal GPS antenna is smaller in appearance than the external one.

Advantages: Simple and convenient to use, no need to connect to the power supply.

Disadvantages: operating radius of 5-10km.

2. External GPS antenna

The working coverage of the external GPS antenna is wider than that of the internal GPS antenna.

Advantages: The operating radius can reach ten kilometers and is stable.

Disadvantages: It consumes electricity, so a built-in power supply is generally required.

Is the car GPS locator antenna built-in or external?

As we all know, the role of car GPS locator is positioning! Therefore, the positioning accuracy of the equipment is very important, so does it mean which type of antenna has a higher positioning accuracy?

That's right, if you just look at positioning accuracy, naturally, whichever position is accurate is better. However, we must know that the positioning accuracy of the car GPS locator is not only determined by the built-in and external antennas. The placement of the equipment, the assembly location and the internal workmanship will all affect the GPS locator’s ability to receive satellite signals. Moreover, whether a locator is good or not is not only determined by the positioning accuracy. The positioning method, alarm function, anti-detection ability, battery storage capacity, workmanship quality, vehicle inspection platform, etc. of the locator also determine the GPS locator. Many factors for good and bad. Therefore, it is the key to choose a big-name GPS manufacturer with quality assurance.
