Mouse (GNSS)
A mouse for a global navigation satellite system (GNSS) is a simple receiver for position data, for example from the Global Positioning System (GPS, here GPS mouse ) or the GLONASS . It is primarily designed for connection to mobile devices such as PDAs and cell phones .
The receiving device only consists of an electronic assembly that receives data and converts it into a defined data format (usually NMEA format ). The electronics are in a plastic housing - often with a permanent magnet on the back for easy attachment. In contrast to GPS receivers, which are offered for use outdoors, the GNSS mouse does not have a display or other components for interacting with the operator.
The mouse has a cable and plug in various designs (e.g. USB ) for connection to the end device . In the meantime, wireless devices are also available that communicate with the end device via a Bluetooth interface , for example . The mouse is supplied with power either via the terminal device or via a Y-cable from another source (e.g. a cigarette lighter in the car). In the wireless version, the power supply is often provided by rechargeable batteries integrated in the GNSS mouse .
By connecting a mouse, it is possible to use the mobile device as a mobile navigation system - provided the appropriate software is available .
GPS loggers are also often referred to as GPS mice . These are devices that record data independently, but only display rudimentary data. The data is evaluated on a computer after the saved data has been transferred there.
