The GPS speedometer is a measuring device that instantly determines the speed of movement. According to the measurement method, centrifugal, chronometric, vibration, induction, electromagnetic and satellite speedometers are distinguished.
What is this?
GPS-speedometer works on satellite positioning system. The device determines the speed electronically as the distance traveled divided by the travel time. It removes the speed signal, but with a small error. According to the type of indicator, they are analog, pointer, tape, drum and digital. The digital speedometer indicator is a liquid crystal display that displays the speed in numbers.
The main problem with such a device is rapidly changing speed indicators or long delays in readings. All this leads to the fact that the speed data at a certain point in time, for example, during braking and acceleration, are indicated incorrectly. The most popular are analog speedometers. Digital is used in a few models.
Digital GPS speedometer has its pros and cons. On the one hand, this is a modern device with an attractivedesign and small size, on the other hand, the presence of errors, constant jumps in numbers knock the driver down and distract from the road with inaccurate indicators. Despite the classification, absolutely all speedometers have an error in readings. Manufacturers of these technical devices create devices in such a way that their performance tends to increase against the actual speed of movement. It is measured as a percentage.
What do you need?
GPS speedometer for "Android" - a handy program with which you can measure the speed of movement. In order to use it, you need to download the application to your smartphone, run it and find an active connection. This speedometer is ideal for bicycles and cars. It shows the total distance, current speed, has a counter. A significant drawback of the program is a large error. The navigation device has the same capabilities, but is installed on the front of the car.
Features
Speedometer on "Android" without GPS performs the same function as a regular device, but without using an active connection. For example, a GPS navigator with EcoDrive Speedometer is a handy device. It is characterized by maximum accuracy, informs the driver about all the characteristics of the movement. The driving economy indicator is based on the analysis of acceleration, speed, elevation changes. Thanks to him, the driver in real time is able to adjust the style of movement and reduce fuel consumption.
On digital instrumentindicators are shown on the display. This information allows the driver to keep under control the time, distance traveled, altitude, average and maximum speed. In order to switch from one information to another, you just need to touch the screen. All nautical speedometers are compact, lightweight, and have an attractive, ultra-modern design.
Such speedometers are suitable for all types of transport: land, water and air. In addition, electronic devices with a GPS system are used for hiking and sports. The difference between Android programs and physical devices lies in the tolerances and price. Speedometers are expensive, unlike apps downloaded to your smartphone.
Models
GPS-speedometer for cars is a modern device offered by many manufacturers of equipment and electronics.
- Dynamite speedometer model is light and compact, easy to use. The device tracks speed and location. Suitable for any cars and water transport. The device has built-in location systems, so you can use it anywhere in the world. Responds quickly to movement, consumes little energy; liquid crystal screen, waterproof, displays average, current and maximum speed, distance and GPS coordinates. Tracks speed up to 900 km/h. Price - 7350 rubles.
- GPS-speedometer SkyRC Speed Meter - a device that measures speed as accurately as possiblecar, boat, helicopter or plane. In addition, the device records mileage or altitude. Powered by a lithium-ion battery, the battery life is 150 minutes. Light weight, compactness and ease of use are the main advantages of the speedometer. Price - 5490 rubles.
It is easy for a modern driver to find a suitable model of a navigational speedometer if the need arises.
Price
GPS speedometer for cars is not a budget gadget. The cheapest models cost two thousand rubles. The price of more expensive ones is five thousand or more. Such digital gauges are optional if the car is equipped with standard speedometers. Whether or not to equip the dashboard with them is up to the owner.
Reviews
Judging by the reviews, the speedometer with GPS navigation for cars is a useful device. It has a digital speed indicator, a choice of units of measurement, and a flexible analog scale. Many models are equipped with an audible speeding alert, work in the background, and have extended statistics for different periods of time. In addition, the speedometer shows the total time, distance traveled, average and maximum speed, average economy, maximum acceleration and braking, the highest and lowest point of the path. The disadvantages include the high price of functional models, the presence of errors, rapidly changing numbers.
