Chapter 3 OEM7 Receiver Operation
CPT7 and CPT7700 Installation and Operation User Manual v12

To receive corrections, 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
on page 16 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 PPP 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
below and
3.3.1 Defining Antenna and Base Antenna
The type of antenna for the receiver and/or the base receiver can be defined using the
THISANTENNATYPE
command and
BASEANTENNATYPE
command respectively.
The Phase Center Variation (PCV) and the Phase Center Offset (PCO) for each can also be specified using
the
THISANTENNAPCV
command and
THISANTENNAPCO
command or the
BASEANTENNAPCV
command and
BASEANTENNAPCO
command.
Refer to the
OEM7 Commands and Logs Reference Manual
for command details.

serialconfig [port] baud [parity[databits[stopbits[handshaking[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
