The use of obd gps tracker is now more extensive, and more people use it. At the same time, there are many misunderstandings about obd gps tracker on the market. More and more people believe this kind of misunderstanding, so that they feel that the obd gps tracker they bought is not the same as what they imagined. This kind of misunderstanding that has been formed for a long time, today I will discuss with you one or two.

One: GPS can be positioned anytime, anywhere?

The obd gps tracker does not have signals everywhere, and there are many influencing factors that interfere with the locator to complete satellite signal reception when the signal is insufficient. Predictable such as trees on the street, invisible such as electromagnetic waves, etc., these are the normal signal searches that affect the obd gps tracker.

Even so, there are solutions. For details, please refer to the previous article "Why do GPS positioning and LBS positioning appear at the same time?" ". But even then, there will always be places where neither signal is present. So it is not accurate to say that obd gps tracker can locate anytime, anywhere.

Two: The obd gps tracker signal map shows the signal quality of the device?

When people buy obd gps tracker offline, more and more merchants will explain the signal quality of the device to you based on the number of device information displayed on the computer platform or APP. Indeed, according to this method can be used as a basis for identification, but it is not absolute. What's more, there are still many merchants who will make this signal value look more contagious according to some modified software. Therefore, when purchasing, you should not believe this statement too much, and you must have your own judgment and choose from other aspects.

Three: More and more obd gps trackers that can locate indoors?

As mentioned above, there are many factors that affect the locator signal, and one of them is the skyscrapers that are common in our daily life. Indoors, also in the building. Since such buildings are covered with concrete and metal, the signal cannot pass through. Except the window can receive the signal. Most of the signals that you can see indoors are actually from LBS base stations or Wi-Fi positioning. These three positioning methods have their own advantages and disadvantages, and according to the current technology, it is temporarily impossible to change their original characteristics.

Four: Is there an obd gps tracker without a card?

This is also the biggest rumor. The said card-free locator does not mean that no card is inserted, but the manufacturer has built the card into the device according to the needs. Without the card, the device has no signal, and the signal transmission cannot be completed. And if such a card-free locator fails, the subsequent maintenance is also very troublesome, which greatly affects the experience for users.

Finally, I suggest that you should not only consider a single factor when deciding to buy an obd gps tracker, but remember to prepare your homework in advance. It is best to choose a big brand, and professional sales staff will tell you the suitable model before purchasing, and then the service guarantee will be more comprehensive.

For most electronic products, the working temperature is too high or too low, which will interfere with the daily use of the device. Just like the tablet computer that everyone loves, it is easy to fail to charge when the weather is cold. Electronic products such as magnetic gps locator that basically operate outdoors and must read satellite signals to complete their daily work are also subject to interference from the external environment.

1. The temperature range accepted by the positioner

The working temperature of the positioning device has been mentioned in some articles before, which is generally around -20-70 °C.

Judging from this type of data, many people may feel that it does not matter, and there will be no such extreme temperatures in daily temperatures. It's not actually the case, these temperature categories simply mean that the magnetic gps locator can keep running, but not necessarily at optimal efficiency. In the winter in the north, even -20 degrees is normal, not to mention some special environments, the temperature will only be lower. Plus, in summer, there's no guarantee that every car will be parked in a shaded garage every time. If it is outdoors, then in a closed area like the inside of the car, the temperature is definitely higher than the outside. Not to mention those parked directly under the sun.

2. The optimal temperature for the positioner to operate

In fact, the optimum working temperature for the magnetic gps locator to have the best working efficiency is about 15-35 °C. If the above two weather conditions are encountered, the locator is still installed outside the car, and this type of locator is directly exposed to the car. The external environment is more easily disturbed by the environment.

3. What happens when the temperature is out of range?

Generally speaking, if the operating temperature of the magnetic gps locator exceeds the acceptable range, it will automatically shut down and stop running to protect the parts of the device. There will be no automatic damage to the equipment. For example, people often ask, will the sun exposure locator explode in summer? The explosion of the magnetic gps locator is mostly due to the problem of the wiring. The wiring is not connected correctly, causing the parts of the device to change and conflict. In addition, it is exposed to the high temperature of the sun, which will cause the explosion. If you make sure that your magnetic gps locator is installed correctly, it is difficult to have an explosion in the car. This is the case in low temperature environments.

In general, extreme weather conditions will cause corresponding interference to the daily operation of the magnetic gps locator, not only the temperature, but also the weather. But in weather like this, most of you won't go out. Usually, it is enough to pay attention to the installation environment and method of the magnetic gps locator.

1. Product stability. Consider choosing 4g cat gps tracking with strong anti-electromagnetic interference and stable functions. When the vehicle is fluctuated, the temperature is high, there is electromagnetic interference, and the environment inside the vehicle is relatively poor, it will affect the operation of the GPS.

2. Select operators carefully. It is necessary to consider choosing an operator with a strong and sustainable network, so as to avoid the network coverage area is too small or the company cannot get reliable follow-up services due to bankruptcy.

3. Distinguish module level. GPS modules are divided into two grades, civil grade and industrial grade. Industrial-grade modules have stable functions and are relatively expensive; civilian-grade modules are less adaptable to the environment, but relatively cheap. Customers need to consider the price/performance ratio.

4. Safe energy delivery. The energy consumption of GPS is relatively large, and a special power supply for GPS should be set up to avoid the failure of circuit burnout due to unstable frequency of general power supply in poor environment. The car connecting line has a large amount of current, and the general connecting line is easy to burn. The quality of the connecting line must be good to ensure reliability and safety.

5. The aesthetics of the product. 4g cat gps tracking is generally a concealed installation, but high-end products usually come with a car phone (handle). When purchasing, consider whether the handle is fashionable, whether it is beautiful in shape, and whether it is in harmony with the front bezel and interior color.

In the process of replaying the vehicle trajectory, sometimes we will find that the driving route of the vehicle becomes a straight line. It greatly affects the track management and mileage statistics of the vehicle, and also greatly reduces the experience of using the 4g lte gps tracker.

First of all, it is necessary to determine whether the 4g lte gps tracker has been like this since it was installed, or whether it is normal to use it in the early stage, and suddenly the driving route of the vehicle becomes a straight line at a certain time in the later stage.

If it is the first case, this type must be checked from the installation, especially when the 4g lte gps tracker is in the metal shell or the top of the device is metal, the 4g lte gps tracker will be out of position. The principle It is metal materials that will reflect GPS positioning signals and communication signals.

If it is the second case, you need to check the indicator light of the device. If the indicator light also shows abnormal status, you need to replace the external GPS antenna. If the GPS antenna has been replaced and the problem still exists, you need to check the 4g lte gps The host of the tracker. This work is more complicated, it is best to report the problem to the supplier of 4g lte gps tracker in time, and their technical staff will assist in handling it.

Finally, in the second case, in the actual application scenario, there may still be situations where the GPS signal is unstable. When there are jammers and interference devices near the 4g lte gps tracker, the driving route of the vehicle will also become a straight line. This shows that There may be military-controlled areas, examination rooms, and special workplaces nearby.
