Advantages of adding GPS to a driver's record

Many modern drive recorders are equipped with GPS. However, some people seem to be unsure of the advantages, so we will explain them here.

Knowing the exact location at the time of an accident

With GPS, the exact location of the accident is recorded. If you are driving a long distance, it may be difficult to recall the exact address where the accident occurred later. In addition, you may not even be aware of the accident at the time of the accident. However, if the location information is recorded by GPS, the exact address can be confirmed later by checking the video recording.

Accurate date and time at the time of the accident, no time correction required

GPS reception allows accurate date and time to be recorded at all times without the need to manually correct the time.

Speed and direction of travel at the time of accident

You can determine how fast you were going and in which direction you were driving at the time of the accident.
This will prove that you were not speeding and will provide a more detailed understanding of the circumstances of the accident.

A more accurate speed can be determined.

This is due to the fact that speedometers installed in vehicles are not always accurate, in fact, they usually have a margin of error.

The standard speedometer on a vehicle uses a sensor to detect the number of rotations of the axle and calculates the speed from that, and thus, for example, a change in the tire diameter due to wear or a change in the friction coefficient due to road conditions can cause an error.
Incidentally, the allowable range for vehicle inspection is 30.9 km/h to 42.55 km/h for actual speed, while the speedometer reads 40 km/h. In other words, an error of about 10 km is normal. This means that an error of about 10 km is normal. (Even in new cars, the on-board meter is often set to produce a higher reading than the actual speed.)

In contrast, GPS-based speed calculations are theoretically more accurate than standard vehicle meters because they are based on the vehicle's location information. In reality, there is a problem with the frequency of satellite reception, etc., so the display will have a slight time lag when speeding up or down rapidly, but when maintaining a constant cruising speed on highways, etc., a more accurate speed display can be expected than a vehicle's speedometer.

For various reasons, some people do not want to use GPS because they do not want to keep track of where they are going.
Unlike a smartphone, there is no Internet connection, so if you format the SD card at the end of the drive, there will be no record of your location.
