•
GBx Mode : The GBX receiver outputs corrected GPS positions using the
built-in DGPS beacon receiver as the source of differential corrections.
•
Gx-E Mode : The GBX receiver outputs corrected GPS positions using an
external source of differential corrections.
•
Bx Mode : The GBX receiver outputs RTCM correction information as
received from a valid radiobeacon broadcast.
