About GPS and
satellite signals
The Global Positioning System (GPS) is a worldwide
radio navigation system that includes 24 satellites and
their ground stations that monitor the operation of the
satellites. To use GPS, you need a compatible GPS
receiver. Use Bluetooth connectivity to connect to the
GPS receiver. To start using a compatible GPS receiver
with Bluetooth connectivity, select Connectivity >
Bluetooth.
A GPS terminal receives low-power radio signals from
the satellites and measures the travel time of the
signals. From the travel time, the GPS receiver can
calculate its location to the accuracy of metres.
