GPS/GNSS
GPS/GNSS RT4 Geo models use an integrated GPS/GNSS receiver with an internal
antenna to provide posion informaon. Use Maps to see your locaon
and ensure that the receiver is working. Open the Start menu and select
Maps.
u-blox NEO-M8T GNSS Receiver
The u-blox NEO-M8T with an external antenna port is available as an
upgrade opon for GPS/GNSS in RT4 Geo models. The NEO-M8T can collect
data for post processing. When connected to an external GNSS antenna,
the GPS/GNSS receiver will automacally detect and use the external
antenna. Otherwise, the GNSS receiver will use the internal GNSS antenna.
GPS/GNSS Support
Integrated GPS/GNSS Support in Windows
The Windows operang system provides built-in support for GPS/GNSS
devices. As part of that support, the Windows Sensor and Locaon
plaorm provides a standard way for GPS/GNSS informaon to be made
available to applicaons that have been designed using the Windows
Sensor and Locaon applicaon programming interfaces (APIs).
Legacy Support
In addion to the Sensor and Locaon APIs, legacy applicaons that
require access to a serial port can access NMEA data through a serial COM
port interface. The name of the COM port can be found by using Device
Manager and looking under Ports (COM & LPT) for “u-blox Virtual COM
port (COMx) where “x” is the port number allocated on your device.
