    Free app, showing your current GPS speed, coordinates and some other features.

    DSpeed digital Speedometer app is a free software for Android devices with built-in GPS receiver. It acts as a digital speed gauge, showing the velocity of the vehicle you are in.

    Some features of the speed app include:
    GPS Coordinates
    -Shows you your current GPS position - Longitude, Latitude and Altitude.

    Speed Information
    -Speed in MPH (miles per hour)
    -Maximum Speed
    -Current coordinates

    GPS Speed
    -Your current speed and your maximum velocity, according to the sattelites.

    HUD mode
    -A mirror view of the digits, allowing you to put your phone on the dash of the vehicle, so that the readings of your speed in miles per hour can be reflected from the windshield at night.

    A speedometer or a speed meter is a gauge that measures and displays the instantaneous speed of a land vehicle. Now universally fitted to motor vehicles, they started to be available as options in the 1900s, and as standard equipment from about 1910 onwards. Speedometers for other vehicles have specific names and use other means of sensing speed. For a boat, this is a pit log. For an aircraft, this is an airspeed indicator.

    The speedometer was invented by the Croatian Josip Belušić in 1888, and was originally called a velocimeter.

    GPS devices are positional speedometers, based on how far the receiver has moved since the last measurement. Its speed calculations are not subject to the same sources of error as the vehicle's speedometer (wheel size, transmission/drive ratios). Instead, the GPS's positional accuracy, and therefore the accuracy of its calculated speed, is dependent on the satellite signal quality at the time. Speed calculations will be more accurate at higher speeds, when the ratio of positional error to positional change is lower. The GPS software may also use a moving average calculation to reduce error. Some GPS devices do not take into account the vertical position of the car so will under report the speed by the road's gradient.

    As mentioned in the satnav article, GPS data has been used to overturn a speeding ticket; the GPS logs showed the defendant traveling below the speed limit when they were ticketed. That the data came from a GPS device was likely less important than the fact that it was logged; logs from the vehicle's speedometer could likely have been used instead, had they existed.
