GPS-speedometers: description, characteristics

The GPS speedometer is a measuring device thatinstantly determines the speed of motion. By the method of measurement, centrifugal, chronometric, vibrational, induction, electromagnetic and satellite speedometers are distinguished.

What is it?

The GPS-speedometer works on the satellitepositioning. The device determines the speed electronically as the distance traveled, divided by the time of travel. It removes the speed signal, but with a slight error. By type of indicator, they are analog, arrow, tape, drum and digital. The indicator of the digital speedometer is a liquid crystal display that displays speed in figures.

The main problem of such a device is fastVariable rates or long delays. All this leads to the fact that data about the speed at a certain time, for example, during braking and acceleration, are indicated incorrectly. The most popular are the analog speedometers. Digital is used in a few models.

The digital GPS-speedometer has its pros and cons. On the one hand, this is a modern device with an attractive design and small dimensions, on the other - the presence of errors, constant jumps of figures knock down the driver and distract from the road inaccurate indicators. Despite the classification, absolutely all the speedometers have an error of readings. Manufacturers of these technical devices create devices in such a way that their indicators tend to increase against the actual speed of movement. It is measured in percent.

What is it needed for?

Speedometer GPS for "Android" - a convenient program,with which you can measure the speed of movement. In order to use it, you need to download the application to your smartphone, start and find the active connection. Such a speedometer is ideal for bicycles and cars. It shows the total distance, the current speed, has a counter. A significant shortcoming of the program is a big error. The navigation device has the same capabilities, but is installed on the front panel of the car.

Characteristics

The speedometer on the "Android" without GPS performs the samefunction as a normal device, but without using an active connection. For example, a GPS navigator with an EcoDrive Speedometer is an easy to use device. It is very accurate, informs the driver about all the characteristics of the movement. The indicator of economy of movement is based on the analysis of acceleration, speed, height differences. Thanks to him, the driver in real time is able to adjust the driving style and reduce fuel consumption.

On the digital instrument, the indicators are displayed on thedisplay. This information allows the driver to 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 navigational speedometers are compact, lightweight, have an attractive cutting-edge design.

Such speedometers are suitable for all typestransport: land, water and air. In addition, electronic devices with a GPS-system are used for walking and sports. The difference between the programs on "Android" and physical devices is the permissible errors and price. Speedometers are expensive, unlike the applications downloaded to the smartphone.

Models

GPS-speedometer for cars - a modern device, which offers many manufacturers of technology and electronics.

1. Model of a speedometer from the company Dynamite - Lightweight and compact, easy to use. The device monitors speed and location. Suitable for all cars and water transport. The device has built-in positioning systems, so you can use it anywhere in the world. Quickly responds to movement, consumes little energy; screen liquid crystal, waterproof, displays the average, current and maximum speed, distance and GPS coordinates. Tracks speed up to 900 km / h. The price is 7350 rubles.
2. GPS Speedometer SkyRC Speed ​​Meter - the device that accurately measures the speedcar, boat, helicopter or airplane. In addition, the device records the distance or height. Power is provided 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. The price is 5490 rubles.

It is easy for a modern driver to find a suitable model of a navigation speedometer if such a need arises.

Price

GPS-speedometer for cars does not belong to the budgetgadgets. The cheapest models cost two thousand rubles. The price of more expensive is five thousand and more. Such digital devices are not mandatory if standard speedometers are installed in the machine. Equip them with a dashboard or not - the owner decides.

Reviews

Judging by the reviews, a speedometer with GPS navigation forcars - a useful device. It has a digital speed indicator, a choice of units of measurement, a flexibly adjustable analogue scale. Many models are equipped with an audible alert for speeding, work in the background, have extended statistics for different periods of time. In addition, the speedometer shows the total time, traveled way, average and maximum speed, average economy, maximum acceleration and braking, the highest and lowest way point. The disadvantages include a high price for functional models, the presence of errors, rapidly changing figures.
