Global positioning system (GPS) technology is mainly used to locate a specific object anywhere globally, and it is found in all smart electronic devices, in transport vehicles, and anywhere you have internet access.
However, this technology has diversified to offer other services such as speedometers.
Few people know the GPS Speedometer, don’t know where to buy it, or don’t know how does a GPS speedometer work.
If you are interested in acquiring one and want to know more information, this is the right article for you, keep reading!
GPS Speedometer and Regular Speedometer
Every vehicle has a speedometer on the dashboard or above the steering wheel in the case of a motorcycle.
Also, it has the function of measuring the speed in KM/H or MPH at which the vehicle is traveling.
How Does a Car Speedometer Work?
Turning the wheels produces an electrical voltage proportional to the vehicle’s speed, and this could turn a needle on the speedometer.
In the case of being electronic, the computer will process this electrical voltage and show it on the board as speed.
How Does a GPS Speedometer Work?
If we know that speed is the difference in the position of an object in a given time, GPS technology can provide the exact place of the vehicle, and the integrated circuit of the GPS Speedometer performs the calculations based on the time.
A GPS Speedometer also measures how fast a vehicle travels, but it can be much more precise because it does not depend on magnets or a system that can suffer wear and tear.
If you are looking for an economical GPS car speedometer that will still work perfectly, consider this one found on Amazon. It features a hassle-free plug and play operation, powered via the included cigarette lighter USB cable.
Things You Should Know About The GPS Speedometer
Unlike conventional speedometers, this one is not affected by a harmful change of wheels, by the wear of the magnets, or by damages caused by accidents.
However, we must remember that the satellites are 20,000 km high and that we need to know some things such as:
- The speed measurements could be delayed or altered when passing through a tunnel or through clouds and forests that interfere with the GPS connection with the satellite.
- When there are steep climbs or many slopes, the reading can be affected because the Satellite may not calculate correctly, taking into account the slope of the elevation.
- These speedometers do not have the service of providing the vehicle’s real-time location, but some models do allow it with a history of routes taken included.
Knowing the speed at which you are traveling could save many people’s lives by riding a bus at high speed or estimating the arrival time at a specific destination.
However, it is recommended to use the GPS Speedometer in conjunction with a traditional vehicle speedometer since this will allow accurate information on the speed to be obtained and not depend on the absence of dense clouds on the road.
