GPS Option (WR-G3E-GPS)
|
This hardware/software option consists of an integrated GPS receiver and antenna (with USB interface) and application mapping software with a high-resolution world map licensed by NASA. When combined with the G33EM receiver, this option provides a continuous position display, superimposed on a zoomable high-resolution map of the world. Logging course co-ordinates into a ".csv" file is also provided, with user-definable logging intervals. |
