Chapter 3 OEM7 Receiver Operation
OEM7 Installation and Operation User Manual v1 46
For information on positioning errors and the application of corrections for them, refer to the
application note APN-051 Positioning Modes of Operation, available at www.nova-
tel.com/support/. To receive corrections, a data link between the base station and the rover sta-
tion 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 Customer Support on page12 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
Base Station Configuration below and Rover Station Configuration on the next page.
3.3.1 Base Station Configuration
At the base station, enter the following commands:
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 Figure 15: Basic
Differential Setup on the previous page)
saveconfig (optional)
For example:
RTK Automated Correction Generation
fix position lat lon hgt (enter your own lat, lon, hgt)
generatertkcorrections rtcmv3 com2
RTCM V3
serialconfig com2 9600 N 8 1 N on
interfacemode com2 none rtcmv3 off
fix position lat lon hgt (enter your own lat, lon, hgt)
log com2 rtcm1002 ontime 1 (for L1 only models)
log com2 rtcm1004 ontime 1 (for L1/L2 models)
log com2 rtcm1006 ontime 10
log com2 rtcm1019 ontime 120
saveconfig (optional)
RTCM V3 with GLONASS
serialconfig com2 9600 N 8 1 N on
interfacemode com2 none rtcmv3 off
