Configuration Notes
For compatibility with other GNSS receivers and to minimize message size, use the standard form of
RTCA, RTCM, RTCMV3, CMR+ or CMR corrections shown in the base and rover examples above. This
requires using the
INTERFACEMODE
command to dedicate one direction of a serial port to one
message type only. When the
INTERFACEMODE
command is used to change the mode from the
NOVATEL default, the NovAtel format messages can no longer be used.
To mix NovAtel format messages and RTCA, RTCM, RTCMV3 or CMR messages on the same port,
leave the interface mode set to NOVATEL and log out variants of the standard correction messages with
a NovAtel header. ASCII or binary variants can be requested by appending an A or B to the standard
message name. For example, on the base station:
interfacemode com2 novatel novatel
fix position 51.11358042 -114.04358013 1059.4105
log com2 rtcaobs2b ontime 2
At the rover, leave the interface mode default settings (interfacemode com2 novatel novatel). The rover
recognizes the default and uses the corrections it receives with a NovAtel header.
A
The position type is OPERATIONAL.
Higher accuracy corrections are lost. The receiver changes to a lower accuracy solution.
Steadyline operates in Maintain mode while solution accuracy remains within the Operational limit.
B
The solution accuracy exceeds the operational limit. The position type changes to WARNING.
The Steadyline mode changes from Maintain to Transition.
C
The solution accuracy exceeds the warning limit. The position type changes to OUT_OF_BOUNDS.
Steadyline is disabled.

1. Interface mode must be set to NOVATEL for the receiver to issue logs with an A or B
suffix.
2. Using the receiver in NOVATEL mode consumes more CPU bandwidth than using the
native differential messages as shown in
Section 4.3.1, Base Station Configuration on
