About GPS and GNSS

The VM9424 uses a vehicle GPS (Global Positioning System)-based
navigation device which utilizes digital map data to guide you from your
selected location A to location B, using location information obtained from a
Global Navigation Satellite System (GNSS).
A GNSS consists of a set of satellites that transmit high-frequency radio
signals containing time, direction, and distance data that can be picked up by a
receiver, allowing users to pinpoint their precise locations anywhere around
the globe. Navigation Satellite Receivers (GPS devices) use this transmitted
information to calculate an exact location on the earth. Every point on Earth
can be identified by latitude and longitude. The receiver uses the information
sent by at least three satellites and determines the coordinates of the receiving
device.
By comparing the time the signals were transmitted from the satellites and the
time they were recorded, the receiver calculates how far away each satellite is.
The distance of the receiver from three or more satellites reflects its position
on the surface of the planet. Using these distance measurements, the receiver
might also be able to calculate speed, bearing, trip time, distance to
destination, altitude, etc. The GPS position may be displayed as a point on a
digital map (at least hree satellites' signals must be received) and as the GPS
device moves the corresponding trace is displayed as well.
Please keep in mind that although the radio signals of navigation satellites will
pass through clouds, glass, plastic, and other lightweight materials, satellite-
navigation receivers will not work underground or in some enclosed spaces.
