In daily life, when we use mobile phones, we will encounter the situation that the mobile phone cannot work without signal. This is because the card in the mobile phone cannot receive the signal from the base station, thus interrupting the work. Everyone knows that without a signal, a mobile phone cannot access the Internet, send messages, etc., which is really troublesome. As a GPS tracker for electronic products, a SIM card is also required to receive and upload data to the user.
Since the mobile phone will encounter no signal, then GPS locator will naturally have. Some people say that gps tracker for my car has no signal, what’s wrong? Generally, this can be divided into two cases, one is that there is no signal to receive location information; the other is that there is no signal to upload data information. Let’s talk about these two situations separately：
GPS positioning equipment mainly depends on intercepting satellite signals and calculating satellite trajectory movement data so as to obtain our location information, driving trajectory information and so on. Therefore, device signal reception is also very important.
GPS tracker signal reception has a great relationship with the location of the tracker, the installation of the tracker, and the tracker itself. Poor environmental signals where the tracker is located, improper installation of the tracker, and problems with the signal receiving section of the tracker itself can cause the tracker to receive no signal.
If the GPS signal is strong in the area, you can quickly receive the positioning signal. If the GPS signal is weak, you need to wait for a long time to receive the signal. If there is no signal for a while, you can wait for a while.
When the tracker cannot receive the signal for a long time, then we can consider whether the tracker is installed or the tracker itself has a problem.
The tracker must be installed with the front side up and no metal covering the periphery. If the surrounding of the tracker is covered with a lot of metal materials, the signal reception of the tracker will be interfered, and it may not be able to receive the signal.
In addition, tall and dense buildings (such as in tunnels, between high-rise buildings, underground parking lots, under viaducts, etc.) and weather changes or satellite signal closures may affect the GPS tracker signal reception, resulting in Unable to locate or inaccurate positioning, failure of navigation operation and malfunction of the system, etc.
If it is determined that the positioner is not a problem with the installation, it is likely that the positioner itself is malfunctioning. This device failure may be due to damage to the device’s antenna or a problem with the signal section inside the device. If it is the equipment that causes these problems, it is recommended to contact the merchant directly to repair the equipment. If you bought at SEEWORLD, you can ask our staff.
The second case is that there is no problem with the signal reception, and when there is no signal when uploading data, it will also cause the user to not see the data of the GPS tracker. Because the device uploads data requires a cellular network. Sometimes the cellular network fails, and data cannot be uploaded to the background. Some people think that the GPS tracker is out of signal.
If you see that the GPS device does not have the latest location on the background, you need to first determine whether it is a device reception problem or a problem in the data upload process, and then solve it.
