For information on positioning errors and the application of corrections for them, refer to the application

. To receive
corrections with a base/rover setup, a data link between the base station and the rover station is
required. The base and rover stations can both be NovAtel receivers, however NovAtel receivers will
work with some other brands. Contact Customer Support for further details (refer to
for details).
The data link should support a rate of at least 19200 bits per second, but a rate of 115200 bits per
second, with less than 4.0 s latency, is recommended. Unlike the base/rover concept, SBAS and L-Band
corrections can be applied directly to a single receiver.
When the base and rover are set up, configure them as shown in the configuration examples in
Sections
and
4.3.1
Base Station Configuration
At the base station, enter the following commands:
serialconfig [port] baud [parity[databits[stopbits[handshak-
ing[break]]]]]
interfacemode port rx_type tx_type [responses]
fix position latitude longitude height
(
enter your own lat, long and hgt values)
log port message [trigger [period]]
(port = COM2 / refer to
above)
saveconfig
(optional)
