GPS speedometer is a measuring device that instantly determines the speed of movement. According to the measurement method, centrifugal, chronometric, vibrational, induction, electromagnetic and satellite speedometers are distinguished.
What is it?
GPS speedometer works by satellite positioning system . The device determines the speed electronically as the distance traveled, divided by the travel time. It takes a signal of speed of movement, but with a small error. By the type of indicator, they are analog, arrow, tape, drum and digital. The digital speedometer indicator is a liquid crystal display that displays the speed in numbers.
The main problem of 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 are 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 size, on the other hand, the presence of errors, constant jumps in numbers knock the driver and distract from the road with inaccurate indicators. Despite the classification, absolutely all speedometers have an error of 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 is it needed for?
GPS speedometer for Android is a convenient program with which you can measure the speed of movement. In order to use it, you need to download the application on your smartphone, start and find the 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 panel of the car.
Specifications
The 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 an econometric EcoDrive Speedometer is a convenient device. It is characterized by maximum accuracy, informs the driver about all the characteristics of the movement. The indicator of economy of movement is based on the analysis of acceleration, speed, elevation. Thanks to him, the driver in real time is able to adjust the style of movement and reduce fuel consumption.
On the digital instrument, indicators are shown on the display. This information allows the driver to control the time, distance traveled, altitude, average and maximum speeds. In order to switch from one information to another, you just need to touch the screen. All navigation speedometers are compact, lightweight, have an attractive ultramodern 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 is in the margin of error and price. Speedometers are expensive, unlike applications downloaded to a smartphone.
Models
GPS speedometer for cars is a modern device that is offered by many manufacturers of equipment and electronics.
- Dynamite's speedometer model is lightweight and compact, easy to use. The device tracks speed and location. Suitable for any 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; LCD screen, waterproof, displays average, current and maximum speeds, distances and GPS coordinates. Tracks speeds of up to 900 km / h. Price - 7350 rubles.
- GPS-speedometer SkyRC Speed Meter - a device that accurately measures the speed of a car, boat, helicopter or aircraft. In addition, the device records mileage or altitude. Power is supplied using a lithium-ion battery, 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 is not a budget gadget. The cheapest models cost two thousand rubles. The price of the more expensive is five thousand and higher. Such digital instruments are not necessary if standard speedometers are installed in the machine. Equip them with the dashboard or not - the owner decides.
Reviews
Judging by the reviews, a speedometer with GPS navigation for cars is a useful device. It has a digital speed indicator, a choice of units of measure, and a flexibly customizable analog scale. Many models are equipped with sound alerts about speeding, work in the background, and have advanced statistics for different periods of time. In addition, the speedometer shows the total time traveled, average and maximum speed, average economy, maximum acceleration and deceleration, the highest and lowest point of the path. The disadvantages include the high price of functional models, the presence of errors, rapidly changing numbers.
