shut off device in the positioning often have a certain error, this is a normal thing, under normal circumstances, most of the locator positioning error will be within 25 meters. However, the positioning error of some positioners is relatively large, and the positioning error of the positioners has even exceeded the positioning error of the normal positioners.

So, why is the positioning deviation of some shut off devices so large?

First, GPS signals lead to deviation

The signal problem is the main reason that causes the positioning deviation of the locator.

When the location signal of the shut off device is poor, the locator may cause network delay, causing the locator to not accurately locate the location of the vehicle, making the positioning offset the actual location.

Some positioners have two positioning modes: GPS positioning and LBS positioning. When the GPS signal of the locator is weak, the locator will automatically switch to LBS positioning. However, the accuracy of LBS positioning also depends on the density of the base station where the locator is located.

If the location of the locator base station is relatively rare, and the distance between the base station and the base station is far, it may also lead to a relatively large deviation of the positioning of the locator.

2. Deviation caused by human causes

Under the interference of human factors, it will also cause certain deviations to the shut off device:

1. Long-term stay of the vehicle leads to delayed position update: when the vehicle stays in the same location for a long time (≧5 days) and moves again, there will be a delay of about 3 minutes for the re-update of the vehicle's position information, resulting in the location information still displayed in the same place after the vehicle has run far away;

2. Wireless devices upload location information at a fixed time, not in real time: The positioning mode of GPS wireless devices is to upload location information at a set point in time, rather than the real-time positioning mode of wired devices. For example, if the positioning time of a wireless device is 12:00 noon every day, then the location information before 12:00 noon every day is the location information at 12:00 the previous day, 12:00 is the current vehicle location information, and then until 12:00 the next day, the vehicle location information displayed on the platform is the location information uploaded at 12:00. If this results in inaccurate positioning, you can adjust the wireless device upload information frequency or use the wired device to obtain real-time positioning function.

Again, it is important to choose a good quality locator product and it is related to your experience.
